Good morning Grid Connections listeners and welcome back to Grid Connections podcast, the
official podcast of Grid Connections Consulting, where we discuss all things from clean

energy to electric vehicles and the power grid connecting all of them together.

In today's episode, we take to the water with David Tyler, managing director of North
America Artemis Technologies, a pioneering company bringing high speed electric hydrofoil

ferries and commercial vessels to more people.

Spun out of the America's Cup racing world, Artemis is leveraging cutting edge aerospace
and EV tech to transform maritime transit with quieter, faster, zero-emission

alternatives.

We dive into how these e-foiler vessels drastically reduce energy use, eliminate diesel
fumes,

and bring new life to urban waterways and cities like San Francisco, New York, and beyond.

From real world deployments and reliability engineering to fast charging maritime
infrastructure and the potential for smarter, more frequent ferry service.

This conversation is packed with insight for anyone interested in the future of
sustainable transportation.

definitely great to be here.

Artemis Technologies is a leader in the electric foiling commercial vessels and we're
actually a spinoff from the Artemis Racing America's Cup Challenge.

We were competing in high performance racing, sailing these amazing catamaran, sort of
going four times the speed of the wind, 60 mile an hour, and a huge jump in terms of

efficiency and technology within high performance racing.

And so we founded Artemis Technologies back in 2017, ready to bring that technology from
high performance racing into the commercial maritime segment.

That's awesome.

I guess for those who might not be familiar, let's even peel it back a little bit.

What is the America's Cup?

Just in case people listening are not familiar.

Yeah, I guess the America's Cup is kind of like the blue ribbon event of inshore yacht
racing.

guess it's kind of a lot of people say it's the Formula One oh of yacht racing.

So generally it kind of competes every three to four years, travels around the world.

And it's really a technology challenge, very much like Formula One motor racing.

Each time there's America's Cup, there's a new design rule.

And basically that sets the parameters of the competition.

And then there'll be a number of entries from different countries across the globe
competing to win this title.

And so that's traditionally a really famous, really impressive.

mean, you're totally right.

I think a great analogy is kind of formula one for the sailing world and for what you guys
are doing.

What, what can, like, how did it come from that to the foil and every, mean, there's a lot
of different, really cool technologies in your product.

So, um, I guess let's kind of break down what makes not only is it electric craft,
obviously, but like, what is the different technologies that makes it really stand out

from like traditional.

I think for a lot of people, especially from the North America side, uh I live in the
Northwest.

So taking like a ferry is nothing like unused, like going to the islands and stuff.

But there might be a lot of listeners who aren't as familiar with how that kind of plays
into and how important electrification.

And then also some of other technology that you're putting into it that really makes it
even more efficient as having such a big impact on this product.

Yeah, we have, as you say, we have this e-foiler technology, which is like a really
combination of a number of different subsystems.

And the fun that the kind of game changing technology within that is hydrofoiling.

For those who don't know what that is, a hydrofoil is basically a wing under the water.

So it's very much like an airplane.

So as a boat starts to accelerate, creates lift, pops a boat out of the water.

And by flying up other ways, we're reducing the friction or reducing the drag.

And that's really important when you're looking at electrification, because it means for a
given volume of energy storage or battery, size of battery on board a boat, we can go

significantly further and faster.

So what we did as a company was really take those efficiency gains created through
development of foils in that high performance racing segment and bring them in commercial

maritime.

Because uh as you're very aware, people

have concerns about range anxiety around electric vehicles.

But that's even worse with boats.

Water is 800 times denser than air.

So simply putting in batteries in a standard vessel, like thinking about, I'm here in New
York, and I see ferries running around.

Putting batteries in those boats, they're significantly impacted in terms of the range
that they can deliver and the speed of operation.

So fundamentally,

electrification in that basic form doesn't really work for high speed boats.

And so what we've done is brought that hydrofoiling technology to effectively increase the
range and operation of electrification of high speed vessels.

And so for, guess I really want to talk about what's interesting about how you're
obviously leveraging the hydrofoil technology, but how is Artemis like really helping with

improved commuting and what, what does that kind of, for people who maybe take a ferry and
especially I'd love to see more of these in the Northwest because the ferries here,

they're pretty big, they're pretty slow.

They're very noisy and they're very smelly.

So I think there's a lot of really cool things.

I'm excited with what your technology has to offer.

Yeah, there's lots of benefits and maybe I'll talk a bit more about the other tech.

So we have the foiling by flying above the waves really reduces the kind of effects of
seasickness and the accelerations that people might feel.

So it means it's a far more comfortable and enjoyable ride when you're on board.

The eFoiler system also has an electric propulsion unit, which is kind of integrated into
the foil under the water.

So the boats are a lot quieter.

And because it's completely electric, there's no diesel fumes.

There's that vibration from the noisy diesel engines that you're used to.

And also the boats can operate at higher speeds, particularly in sea states.

So it means that your high speed or your ferry commute in the morning could be
significantly faster and quieter and more enjoyable.

So far, how is the industry in your conversations really embracing this?

know hydrofoils in some ways have been around or they're really big for some products
previously in the maritime space, but that plus electrification, I'm curious to see or

hear more about what you're seeing from the market.

It's certainly been a journey.

We've been doing this now for seven years.

I think my answer to that question five years ago would be very different to now.

I would say that we're kind of taking a big leap forward because we're combining
electrification with hydrofoiling.

think five years ago, I think maritime was, I'd say it's probably quite an old fashioned
industry.

Probably

quite skeptical of new innovations, complete opposite, I'd say, to the automotive sector
or even aerospace, where they're always trying to push the boundary.

They want the newest technology and they don't want to fall behind.

Whereas the kind of approach within maritime and, you know, a public ferry operator or a
pilot boat operator, they're like, oh, not me.

I don't want to be first.

You know, they want to see it, make sure it's working, it's reliable.

And so trying to talk to customers about this novel technology when we first started was
quite tough.

I always like to talk about a good friend now who's based in Belfast Harbour where the
company is based in the UK.

They've run pilot boats and they were really kind of sceptical of the technology and what
we were doing.

And it was only once we launched the first vessel three years ago that they were kind of
like, oh wow, I get it now.

That's absolutely incredible.

It's going to completely change the way we do our operations.

And I think that's a bit of a journey that we've been on.

We've launched over 10 vessels an hour, we've been on the water for over three years and a
critical thing for getting the market to embrace the technology is really taking it to the

market.

So we're in the middle of a North American tour, taking our boats around the US and now
Canada, to Miami, New York, San Francisco, Seattle, these places where there are big ferry

networks and people really do rely on those vessels to get to work for Lifeline services.

and just really to live their everyday lives.

I think once seeing the videos is one thing, but actually getting them on board, just, you
know, they're completely blown away by it.

Yeah.

And I think that was one of the reasons I was really excited to talk to you and your team
is there's been so many different prototypes, whether that be automotive or even electric

maritime.

And so it's really cool to see a company that actually has a product that's brought to
market.

You already have some out there now kind of expanding that, but let's kind of, guess, uh,
I think there's, we're also really curious about like the infrastructure to charge these

and how that works, but let's, let's just start kind of with, the products that you're,

team is offering and how you see kind of the hydrofoil and electrification technology kind
of expand from what you offer today and then what you're looking to hopefully expand

longer term.

So we've really developed these e-Fuller boats for operations that need to move people or
goods fast.

it's high speed passenger ferry services in places like San Francisco, New York, London
that are getting people to work.

It's pilot boats that operate in ports and harbors that need to get pilots out to big
ships so they can safely navigate them back into port.

It's crew trans-sub vessel operating.

offshore wind farms and providing crew services out to offshore energy platforms.

They're kind of the critical target markets for us.

We really wanted to develop a technology that could really support society and support
those operations needed for us all to either to live in our cities or to get the jobs done

and or to create the energy that we're going to need as a society.

I think there's kind of a lot of exciting additional benefits of the tech.

So one of the things is because we're flying above the water,

We produce very limited wake or kind of water wash when we're operating at high speed.

So that means that we can avoid local speed restrictions or we can operate at high speed
in places that weren't possible before.

So that really opens up the opportunity for new services.

The boats as well, because they're very quiet as well, it means that where ferry services
maybe weren't able to operate in locations or weren't able to start early in the morning,

they can today because it's completely game changing.

But also because we're using so much less energy, because of the drag and the efficiency
is so much better, it really changes the economics of high speed operation too.

So it makes certain ferry operations that weren't um economically viable before viable
today.

Yeah, let's go and pack a little bit.

uh obviously the speed component is what really plays into kind of some of that.

But I would imagine obviously for a traditional vessel, the diesel and all these other
things just cause the expenses to skyrocket and possibly maintenance for kind of a vehicle

that's probably under kind of stress like that.

Can you talk a little bit about that?

And then like, what kind of speeds are we talking about for these boats compared to maybe
traditional ferries?

The boats operate between 25 knots and 35 knots, which I would say is quite typical.

But I think the challenge with high-speed ferry services, the power curve for a fast ferry
is basically exponential when you go from 25 knots here up to

sort of 35 knots, so it becomes very expensive to operate at those high speeds.

And that's part of the reason why a lot of the ferries don't do that, just because
economics don't work.

But the big benefit of our technology is once we kind of take off and we have kind of a
very flat energy demand as we sort of get up to those 35 knot speeds.

So it means that, yeah, we basically, using our technology operator will be able to
increase the speed of their operations.

And that can be a real game changer because even here in New York, I'm based in the
Brooklyn Navy Yard.

If you miss your ferry, sometimes you have to wait 40, 45 minutes, an hour for the next
one.

But if we could be going almost 30 % faster, providing more services to people, will
really start to, you know, will really start to come a real alternative to using the buses

or the subways because people know that if they miss one, they haven't got to wait too
long to the next opportunity to travel on the ferry.

Yeah, I think that's a great call out.

So it's not just really the speed of the ferry itself, but it's actually kind of helps
with the frequency and kind of the traveling.

If you're trying to plan to use one of these, I guess the next question would be like, I
know with some of the larger kind of slower traditional electric ferries, they pretty much

just, they have this really unique charging pad that kind of just comes up against the
side of the wall and more or less kind of wirelessly charges.

It depends on the model, but for some of them, that's how it charges.

when it comes into the port for people to get on and off.

then by the time it's loaded, it's charged again to go.

So I think we'd be kind of curious to learn a bit more about how charging works for an
Artemis vessel and what that looks like for an operator to kind of implement if they maybe

don't have something in place today.

Yeah, we are really leveraging technology from the EV space.

the batteries, we developed our own battery and we're using cells from an automotive
supplier.

And we're also leveraging the technologies developed for electric vehicle charging.

So on the F12 range, there's two options.

You can do a fast DC charge with a CCS2 connector, or you can do a slow AC charge as well.

And then with the bigger F24 or the bigger 150 passenger ferry platform,

going to be utilizing the MCS standard connector.

It will be able to charge up to 2.9 megawatts.

So for both vessel platforms, it is a case of using one liquid cooled cable and being able
to charge the vessel from flat to full in an hour.

wild.

And I guess how what right now is the range of a vessel because I mean, I'm sure you say
it takes an hour to fully charge it.

But a lot of the time you probably don't need to fully charge it just taking advantage of
when it's right there in the port.

Yeah, exactly.

It depends on your timetable and your duty cycle and how you're using the boat.

We have a range on the smaller boat of around 40 to 50 nautical miles, kind of high speed,
foiling speed.

So generally, the most efficient operation is around 25 knots for that platform.

But if you're going six knots, you can go almost double that distance going slowly.

And then with the EF24 platform,

we're able to get a bit more range out of that boat because of the size of the vessel, a
big Academy round.

And so we're able to foil for around 17 nautical miles at 25 knots.

So that means that you can go for two hours foiling continuously pretty fast.

And that's great for operations like commuter ferry services because generally they have
to get through that busy rush hour period in the morning.

during the day, they're generally quieter, so there's opportunities to do longer charges.

So when we model operations for customers, generally you're kind of, you know, you're
delivering a service, you're intermittently charging when you're embarking and

disembarking customers, so you can keep the battery topped up, and then you're using a
longer charging window in the middle of the day to make sure you're fully charged by the

time that busy rush hour period comes in the afternoon, early evening.

Yeah, I think there's some really interesting things that kind of unlocked with this
product and there's a lot of other products you're looking to bring to market.

So I'd love to talk about those too, but uh I guess to start since we've been talking
about specifically kind of the ferry model, like what are some like waterways or other

potential markets that you think maybe have been underutilized that now leveraging this
technology and this product at some of the operational costs that this really unlocks.

I think there's been a general movement to utilize waterways in a better way.

know, San Francisco is particularly hard to talk about that because we are based there,
that's where we're really developing this America's Cup technology.

I was based in

based in downtown San Francisco and I used to commute on the ferry over to Alameda where
we had our America's Cup base.

Where the geography makes sense, like in San Francisco, they're really looking to try and
build that ferry network to try and connect new communities.

As San Francisco is getting busier busier, new residential communities are getting built
outside the city.

There's a lot of traffic obviously going down to San Jose and Silicon Valley.

And really the kind of road and rail networks are oversubscribed and the cost of putting
in a new rail service or putting in a new bridge there is astronomical.

And so the fastest and cheapest way to add capacity is to put on new ferry services.

And that's something that San Francisco Bay ferry or WETA have really seen and that's
their vision over the next few years is actually to try and expand and find more

opportunities and a better ferry service for these people.

And I think they...

public announced only last week that the ridership has bounced back after Covid.

They've got increased ridership, the biggest ridership they've ever had.

uh Bigger than the pre-Covid peak.

I think people like taking the ferry, they like being on the water.

You can get your laptop out, you can have a coffee, you can sit down, you can relax.

And it's a really enjoyable experience.

We talk about the ferry factor.

And it's not going to work for everyone, you need to, it needs to make for you in terms of
where you live or where you work.

But it can be part of the solution when cities are looking to try and decongest their
roads and rail networks for the right cities like San Francisco and New York.

It really does make a difference.

Yeah, I used to go to New York quite a bit for work, but then also lived in the Bay Area
for a little bit.

And uh driving the 101 is definitely something that I dreaded.

And so what I think is really cool is personally, I'm actually working to get my pilot's
license.

And so I think when people talk about like new transportation opportunities in the Bay, I
think the thing that's come up a lot are like EVTOLs.

And personally, I think those are really cool.

Okay.

And I think especially for what you're talking about, like when you're, you have a fairy
like this, especially if you're trying to go from like the East Bay or Southeast Bay and

with the speeds you're talking about this to me, I think there's definitely an argument
for like Evie tolls in certain areas for like point to point.

But as far as like a commuter thing, the idea of like hundreds of these Evie tolls kind of
going in the air in the morning and then the other way in the afternoon, I just don't

think it's like,

realistically the most practical.

But I think that was part of the reason that I was so interested to talk to your company
too was not only do you have a real product that you're actually kind of already

developing and getting out in the real world, but it actually makes sense from that kind
of commuter argument that I think has been one of the bigger proponents for like the EVTOL

space.

And you can actually do this at scale.

And there's just a lot more flexibility without having to come up with all the additional.

Yep.

effective way to increase sustainable public transit

Yeah, definitely.

And I think when we're talking to public transit agencies in particular, they're looking
at a suite of public transport nodes.

And EVTOLs are certainly part of that conversation.

But I think you struck the nail on the head there.

It's just in terms of the cost of infrastructure, the availability of land to actually
have these helipads or EVTOL pads as well.

and landing sites, that's one challenge.

So from a CAPEX cost perspective, I think our product really is exciting for people
because particularly when comparing to traditional fast ferries that are around today, the

technology is a bit more expensive to buy, but you're saving so much on fuel because we're
using anywhere between 70 and 90 % less energy.

So if you're talking about the ferries in San Francisco or New York.

we're saving seven figures a year of fuel generally.

So means that the payback can be within a few years.

And because the total cost of ownership is so much less, we're actually talking to
operators about expanding their services and expanding their fleets, but also looking to

try and, you know, some of these bigger ferries, they're quite busy in the morning, but
then they're actually quite empty during the day.

and you're carrying that cost of having that big vessel all the way through the day, which
is incredibly expensive.

the cost per passenger mile for those midday trips is kind of, know, it's kind of
astronomical really.

It doesn't really make any sense.

But by having a fleet of 150 passenger ferries, having those available to you during those
busy rush hour periods and then being able to take them out of service during those

quieter moments can really change the game in terms of cost.

And that's cost of the tax pay which obviously benefits everyone.

Yeah.

And I think with the other interesting things too, I know we haven't really discussed this
at all is given what you're talking about, about the scale, the cost of operations and

that flexibility to me, there's actually also kind of like a decent kind of software
logistics play with this too, where you could start kind of leveraging more live data.

Like, okay, I'm just going to throw something out like Oakland to, uh, San Francisco in
the mornings really busy, but then

Okay.

could be doing San Francisco to, don't know, somewhere, somewhere else.

And is that something your team's also kind of looking at of like how to kind of, I think
that's what's been really interesting.

The automotive space is, has there been a lot of hype?

Yes.

you

when right now we could actually be putting it to work over here for X, Y, Um, is that
something that Artemis is also kind of exploring and looking at?

Yeah, it's in conjunction with operators because they have their different opportunities
and challenges locally.

as an example, the ferry could be used to provide commuter services in the morning, but
then provide whale watching during the day and actually act as a tourism vessel.

And then you're utilizing that asset the whole time.

So I'd that's kind of one example of what you're alluding to.

So it's kind of like a follow on from, you know, we shouldn't be, we shouldn't be
operating this big boat with 10 people on it.

It's just costing a fortune.

Let's go smaller.

Let's provide more frequent service.

So instead of getting 600 people to come and park their cars all at once and cause chaos
in the car park, why don't we have, you know, 350 passenger ferries and leave every 15

minutes rather than every hour.

And that's just going to speed up everyone's travel time.

and reduce the costs significantly.

So we're having to talk with these kind public transit agencies to maybe rethink their
models.

But also we have to talk to them about the way they procure their vessels and their
technology as well.

Because I think traditionally there would be a tender for a boat and it's kind of, know,
there'd be probably a price battle on delivering a passenger ferry because really the

technology.

You know, you couldn't really tell much difference between a lot of the ferries that are
available in the market.

But there's a difference with our proposal because we're a little bit more expensive, but
then you've got to look at the potential OPEC savings over the lifetime.

So you really need to look at the whole big picture approach.

And that's an education piece which we're doing at the moment.

For sure.

I guess that brings up a question I have is with the hydrofoil and this is my ignorance, I
guess on the product specifically, is that fixed or is that something that actually goes

down?

the reason I'm going to ask this is does that impact the slips in certain spaces that the
ferries can go into?

Yeah, on the EF12, on the smaller boat, the draft is 2.2 meters, about 7 foot.

So generally that boat can get into almost every marina, I'd say.

2.5 meters is typical.

And so there is the option of a trastical system on that boat.

But generally, we try and advise customers not to have it because it's another mechanic.

They're always complaining about service and maintenance, access to parts.

costs over the lifetime.

So what we wanted to do was try and create a product that was rock solid and really easy
to service and maintain.

So on our standard EF12 with the fixed system, we just have the drive unit, which is
integrated into like a nacelle right next to the propeller.

So there's no drive shaft going on the vertical structure of the foil.

It's just the cable going up the vertical into the power electronics and then obviously
into the batteries.

So we wanted to get as many of the mechanical systems out of that boat as we could.

And then on the bigger ferry there, you the bigger boat, you want to be able to operate in
bigger sea states.

that has a draft of around three meters.

So in the majority of places, again, New York, San Francisco, there isn't really an issue
with that draft.

But in places maybe in the Caribbean where there are draft challenges, then there is the
option to have a retractable system.

No, that's great.

guess, uh are there any other examples, kind like what you were just talking about, of the
motor placement, that how your team's kind of designed for really trying to make the boat

as simple and kind of as reliable as possible that you can share with us?

of what we've done in terms of the development of it.

Well, think that the main one really is that having a submerged drive unit so you don't
have to have that drive shaft.

That's really the critical one.

I think in terms of the general benefits of electrification versus a nice combustion
engine.

we're kind of getting all of those benefits in terms of service and maintenance, number of
hours.

um

I kind of, yeah, leveraging those kind of huge jumps and technology games within that
space over the last sort of 20 years.

So the battery technology, the drive unit technology, we're kind of building on that
experience.

And yeah, it's,

I was just kind of speaking of the battery technology.

mean, is that what's really unlocked a lot of this?

mean, is this with the advances we've seen, is this something that wouldn't have been
possible five to 10 years ago?

Or is it that because I think it's really interesting because I get a lot of questions,
especially the automotive side about the battery technology.

And as the battery technology has increased in density, energy density, yes, that's
unlocked more and more capability.

but for the longest time, there's actually still been a pretty large opportunity for
electrification.

And I think it's really interesting talking about how your team has taken advantage of the
battery density, but more importantly, paired that with hydrofoils to really get that

gain, like higher efficiency and make it a much more usable product.

I mean, is that, do you see the battery being still a pretty big limiting factor or was it
really once the hydrofoil was,

just kind of from day one in the design, the batteries weren't really as big of an issue
as maybe it traditionally has been for maritime products.

Yeah, think the big jump in efficiency and reduction in drag from the foils is the really
game-changing part of this technology.

I think we're always trying to improve the energy density of the battery.

So we have a technology roadmap to integrate

new cell technology, new cell chemistry as it comes to market because we can deliver
certain routes today, as I said, 40, 50 miles, 70 miles on the bigger ferry, but in the

future we'd like to be able to serve as 100, 150 miles.

And so that's only really going to come as battery technology really starts to improve.

In the last couple of years, we've seen attempts in increase, I'd say, in energy density.

So there's been some incremental

improvements over time and I think they're going to keep coming and we'll look to
integrate that latest technology into the solution but the fundamental is that the foiling

has kind of been a game changer for electrification of high-speed boats and even in the
future as batteries become more energy dense you know what operators are looking at today

you know they have the infrastructure availability for doing one boat, two boats, three
boats, a small pilot

When you're in New York and you've got a fleet of 38 vessels and you start looking at the
kind of infrastructure required, you're always going to want to have the most efficient

solution possible.

So even if, you know, in the future, say in 10 years time, you still be able to do, you'll
able to do some of those longer routes in New York with batteries alone.

One, you're going to have to have a significantly higher requirement for charging power to
deliver that.

But also you're going to have far higher cost of replacement batteries over the lifetime.

So even in that case, you want to have that foiling solution because it does drive down
your initial capex cost, but also your replacement batteries costs by tens of millions on

those.

No, that's a great point.

um I guess kind of going off of this, and this may be my ignorance in the uh maritime
versus like aviation and automotive worlds.

What is kind of like uh the limiting sea conditions or water conditions for a hydrofoil?

Like obviously when it comes to aviation, like if you're flying a little Cessna, if you
got more than a 15 knot crosswind or something like that, you're not going to, you really

don't want to that thing out.

And I'm kind of curious with hydrofoil technology.

I've seen it be used in some pretty wild water conditions, but I am just kind of curious
if how that plays into this for probably most faring situations.

It's not, but like if you're going maybe from France to England someday and you're going
across the channel, you might get into more serious or like you and the North Sea, more

serious uh sea conditions that might be an issue for hydrophils.

I'm just curious about that.

Yeah, I mean we've engineered our foils for offshore operations.

what I'd say is kind of not every hydrofoil is designed at the same level of operation.

But for us, initially we developed our first system to meet the workboat code, the
maritime and coast guard agency workboat code in the UK.

And so that first vessel Pioneer at Belfast was launched three years ago.

That boat had

workboat cat, I think it's cat two it's called, but basically it can operate up to 60
miles offshore.

And so we wanted to really utilize the benefits of foiling for those offshore conditions
because that's where it can be a game changer because the energy consumption of our ferry

in flat water versus a conventional craft at high speed is about 70 % efficient.

But as soon as you go into one meter wave,

actually become 80 % more efficient.

And as that sea state gets worse, the kind of efficiency differential compared to a
standard boat just increases and increases.

So going offshore or going in waves for electric boats, yeah, it's a bad scenario.

It's a bad equation for them.

And on the EF12 boat, it's really a question of both.

I understand it requires more density, but as far as I've understood, that's kind of one
of the misconceptions I think people see with hydrofoils is they see it only a couple feet

out of the water.

And so they assume, it can't really go into like some serious chop or swells.

But because you're getting like those added efficiencies and stuff having to fight the
waves, you can kind of go over them a lot more than I think most people realize.

Yeah, and I think what I'd say is our foiling boat always outperforms a displacement boat
of the same size, no matter what the sea state is, because you're always getting that

stabilization from the foil and the flight control system.

So on the foil itself, we kind of have these flaps or ailerons, very much like on an
aeroplane.

And as long as you've got sort of like...

As long as you've got kind of flow over that foil, then you're able to use those flaps to
stabilize you.

We've been out in the 12-meter boats in four-meter waves.

We've crossed the RSC from Northern Ireland to Scotland and we had a pioneer on our first
run of doing that trip and we had Seahorse, which is basically the exact same hull, same

cabin.

There's videos on YouTube to check out.

And it was pretty big seas up to kind of four meters and everyone was being very ill on
Seahorse and we're having to transfer people onto the foiling boat to get the green out of

their faces and then put them back.

And so whenever, and they want to ask me that question, I just talk about that real life
case study of us actually operating in those conditions.

Would you say like some of the challenge traditionally or kind of the reason hydrofoils
haven't become more common?

Was it just because of like the traditional additional engineering?

mean, talking about kind of the flaps and kind of that management of that.

mean, nowadays that's really not that complex of a system, but I think what, cause I've
always just thought this technology was just so fascinating and the gains you get are so

impressive.

I'm curious if there's anything you can share of what maybe traditionally has been a bit
of the issue is it.

Because I think in a modern era with between the hardware and even like some of the stuff
you can unlock with software for, I mean, we're even seeing this with planes and like

almost leveraging similar to noise canceling technology to get rid of turbulence.

You could do some similar things that are pretty cool going through waves or other kind of
rougher conditions.

Yeah, definitely.

And I think one thing I always see is on LinkedIn is people say, it didn't work in the 80s
or 90s.

Well, that was quite a long time ago.

Technology's quite a long way since the 80s, I have to say.

Just because it didn't work back then.

I that's the case today.

And I think on that point, there were, there's kind of like fixed foils that are surface
piercing.

I don't know if you've ever been to Greece and everything's called the flying dolphins and
they have, kind of this, it's called the Euro foil design, but it had a lot of structure

under the water.

So there are a lot of appendages.

And whilst you've got a benefit in ride comfort, you weren't really getting much benefit
in terms of fuel consumption and efficiency.

And so that product didn't really take off in a big way.

And then you had the jet foil, which was developed by Boeing.

It was operating in the 90s.

The US Navy were using them.

There's still jet foils being operated in, I think, Hong Kong, South Korea today.

And that was a huge jump in terms of technology and innovation back then.

And that boat used submerged foils with controllable appendages.

uh

flight control system.

But the challenge with that boat is that it had a water jet system integrated into the
foil and it used jet fuel.

So you've got some efficiency savings but the cost of the fuel was incredibly high.

Because you had this water jet system the foil wasn't as efficient as it could be.

And so what we've done with our e-foiler system is we have very efficient carbon fiber
foils that have been developed through the America's Cup.

And when you're efficient, they become very unstable.

So you really need the active flight control system to be able to stabilize those foils
when they do become efficient.

I think it's that combination of composite engineering, being able to have control surface
and complex algorithms to be able to control these boats in ways, combined with the

militarization of electric drive train and being able to actually house that in the

and you know next to the propeller itself it means we don't have to this drive shaft going
on the vertical structure as well and I think in the past you know just managing that z

drive system mechanically I think they were breaking down a lot and it was causing a lot
of problems so we've really eradicated that issue with our tech.

No, that's interesting.

mean, kind of speaking to that, I could also see just like the torque.

I mean, one of the big pros of electric motors is the torque you can kind of unleash and
use that however you want.

And if you start putting them into drives, you can design it for that.

But just in my experience, especially the more complex the drive is between the actual
unit you're trying to move down either through the water or down the road, uh it just puts

more and more strain on the mechanical side versus just having more of a direct

saying, mean, do you have to do a pretty serious gear reduction or is it pretty much like
almost a one to one for, uh, the motor to the propeller?

Yeah, we have a gear reduction because of the technology we're utilizing.

don't want the same prop speed as the motor, so we do have to do that.

And that's been part of the development over the, especially in the early phases, is
having a, you know, that.

that EDU or electric drive unit, making sure that as a unit is robust and reliable.

Because we're developing this technology not for people that are going to be using these
boats, you know, every now and again at a weekend or just in the summer months.

These are for commercial operations, for lifeline services, and they need to be able to
be, they need to work in every day in some pretty tough and challenging conditions.

And so that's really been our, that's been our driver in terms of development of our
technology in particular.

would have been quite quick to get a foiling electric boat on the water but that doesn't
you know that's not what that's not what's required.

You need that robustness, you need that reliability and you also need to meet the
requirements of the maritime regulatory authorities which is not always an easy feat I can

tell you.

Yeah, I guess that brings up couple questions.

um given like the cooling requirements of the motor, because you're dealing with the water
and it's going to be kind of partially submerged anyway, with how you have it designed, I

mean, is that actually giving you a natural amount of cooling for the motor?

And then it kind of keeps what you have to do.

I mean, to me, that actually is a huge advantage in a maritime application for commercial
usage.

Not that even in automotive, they get super hot, but it is something you have to uh

manage and kind of deal with.

And it seems like having all that abundant water that's so much cooler, probably
engineering wise can be something you can really use to your advantage.

Yeah, we do.

do.

um The liquid cooling or surface cooling of that drive unit definitely does help.

And then we actually, can use the water to.

bring water into the heat exchanger to cool the glycol for the battery system as well.

So we're utilising being in the elements of the water.

But that's really a critical thing, managing the temperature not over the motor but of the
batteries, particularly when you're operating in places like the Middle East where they

see very, very high temperatures.

And kind of going back to what you mentioned about like some of the regulatory hurdles uh
and kind of making sure you're meeting those standards.

Is that pretty universal like internationally or are there, have there been kind of unique
challenges?

Maybe you've had to see coming more to the U S side versus Europe or other kind of
international markets.

No, it's not universal.

So in the maritime space, it's basically the flag state sets the requirements.

I think the good thing for us is that we were based in the UK and we were working towards
the maritime and coast guard agencies rules.

And I would say they probably have the probably highest threshold in terms of safety of
operation.

I think the fact that the UK is an island

We've got the North Sea, we've got some pretty challenging...

Yeah, exactly.

I think we have that heritage, obviously, within the Marathon space, both in terms of
engineering and insurance and everything else.

And the Lloyd's Register class society has really been driving things for a very long time
in that regard.

So we were always developing our technology to meet a pretty high safety threshold, which
puts us in good shape when we look to implement our technology in other locations.

including the US.

But the challenge we had is that the rules weren't written for foiling electric boats.

So there were some rules around batteries on boats, but generally the rules were behind
the technology, where the technology was in terms of practice.

And so we've been part of consultative groups from industry to support the regulators in
terms of framing those new rules to make them fit for purpose.

But where there weren't rules like for

rules around the closing control system for the flight control.

We really had to work closely with the class societies because the flag states are kind
of, they don't have the internal expertise.

They're kind of saying, no, we're going to, we're going to assign that approval and sign
off to the class society.

So you need to kind of work with them on it.

And so it's been like a bit of a collaboration working closely with them.

And it has the electrification side been the biggest challenge for those kinds of concerns
or is it just the fact that you're dealing with electrification and foiling that's just a

lot all at once.

think it's a lot all at once, but I think there was things in place around battery
technology and electric drives and things like that.

So um yeah, there's been a wider industry adoption to electrification technology.

The foiling is kind of something on top in addition.

I know we've kind of talked about it more from the business perspective, kind like the
sustainability and efficiency, but I'm kind of curious if there's anything else you can

share.

Obviously a big driver.

A lot of cities have their own kind of sustainability goals and same with countries and
states.

So I'm just kind of curious if there's any advantages.

I mean, obviously there's advantages, but like what has really stood out about Artemis in
that industry to really help these cities can achieve or kind of move forward with a lot

of these sustainability goals they have.

I'm kind of glad you brought it up because I think the whole purpose of what we did this
was to support the decarbonisation of that sector and you going back to our heritage we

were racing in these amazing places Bermuda we were based in Bermuda for a number of years
a couple of years and

We had these polluting sort of chase boats that were chasing around these high performance
cameras.

were, you know, we're spending a fortune on diesel.

They were dropping oil into this beautiful place.

just, you know, you felt guilty from, from doing that.

And that's where we're really, where we've come from.

you know, you can't, you can't, need to develop something that makes sense to the
customer.

Otherwise you can't change anything.

And so.

It's almost like I don't even talk about the environmental aspects of this technology
anymore.

I really need to prove to our customers that it makes business sense for them and that
it's going to be sustainable.

And so that's kind of what I really focus on at the moment.

But yeah, all of these boats are zero emissions in operation.

They're going to have a huge impact in terms of reducing both water and air pollution in
the places where these boats operate.

And it's a big challenge.

No, I mean, that's great.

And yeah, I think a lot of the automotive uh world gets kind of the attention for
decarbonizing.

And obviously there's a lot of benefits for electrification for that space.

But I mean, if you look at the shipping, I mean, especially when you start getting into
large cargo ships and stuff like that, just some of the diesel things.

uh But even then the impact of smaller boats and being able to electrify them and there's
still such a large, even if the batteries aren't where people want them long term, there's

still such a large opportunity.

kind of in the current space for maritime to be electrified.

I guess having said that, I'd be curious.

We've also talked a little bit about what you see the future is, but like, what are some
additional products and kind of like what you see the future of Artemis being moving

forward?

So we just launched our first crew transfer boat.

So this is hot off the press.

I think there's going to be an announcement next week.

So we're demonstrating that CTV up in Aberdeen with customers there.

So that's pretty cool.

So that's decarbonizing of those crew daily crew transfer operations.

So that's really exciting.

And then the first pilot boat is progressing and that will be launched later this year as
well.

So really starting to kind of diversify the portfolio.

of the offer.

And in the future, there's a lot of subsystem technology that could have application
outside of our foiling boats.

So whether it's a propulsion unit or the battery system, the collision avoidance system
that we're developing at the moment as well could support other non-foiling operations in

the future.

Well, I'm kind of curious too, when you, I mean, you go to your website, there's some
really cool, obviously boats you currently have and then kind of some other vessels, but

obviously coming from the America cup background, I've got to imagine there must be
something kind of going around your mind as to what using all this technology, you could

put it into a race boat or what, I mean, what do you see as far as like the racing
opportunities for this technology?

I think we're getting a trickle down benefit from that technology and we have a consulting
business.

we work with a number of the cell GP teams.

Some of them still use our simulator to do training.

We also provide engineering services to other high performance racing teams within that
space.

So from an engineering team and a company perspective, we're still in that area where
we're kind of pushing the boundaries and the limits and developing the

the technology at the sharp end.

And then really we're leveraging that experience and then bringing it into the commercial
segment.

So I think it's always going to be that trickle down.

But I think that development of this technology for our application, I think there's going
to be trickle down to other applications of marine operation.

And hopefully, you know,

you know, bringing driving the cost down of batteries.

So electrification of recreational boats becomes more achievable and feelable in the
future.

That's fair.

guess I do know, I believe it's called E1 where there is the racing electric series and it
does also kind of use a hydrofoil technology with their boats, correct?

Yeah, yeah, does.

it's kind of.

They're really interesting designs because the foil is like pretty far back on the actual
bow.

Yeah, and I think that I would say that I wouldn't say that's the pinnacle of foiling
engineering.

think that's more of a, you know, they have a vessel they have a design and I think
they're creating, they're creating entertainment, right?

So we, we, we had something, you know, when we were racing in the America's Cup, it was,
you know, the best way to control those foiling boats would have been to have a computer

doing it and have an autopilot, but then there'll be no human error.

And so the races will be incredibly boring.

And so think when you're looking at sport and entertainment, you don't want the cleanest,
the best, most advanced solution because then you lose all the interest.

You lose all the excitement because you want those moments of something breaking or a
human error in their maneuver or something like that making the racing exciting.

So I think we've got to be careful that we still keep that within the sport.

No, that's fair.

And that's kind of what I was alluding to.

was kind of curious on your thoughts of that, because there is kind of that balance as to
like looking at your designs.

They're beautiful and really interesting.

But I was curious what and I think that's really true.

We're seeing with a lot of automation that it is turned almost pulled back on the fun,
whether you're talking about that industry or other kind of race series.

So I was just kind of curious.

I mean, if you were to design your ideal racing boat real quickly, I mean, like.

Is there anything that you're seeing with that series that you would do differently that
you could kind of share?

I think our focus is on, it's not something we're really kind of, yeah, it's not something
I guess we're really kind of considered.

I mean, for you, do you find that, do you find the America's Cup is kind like the pinnacle
of racing and much more enjoyable because of how manual it is still?

And even though it is kind of the cutting edge of technology, it's kind of that perfect
balance of, um, bringing new technologies, but also having influence over the destiny of

the outcome.

I think the key thing in America's Cup like it is in Formula One is that there's rule
changes on a frequent basis.

if you get Mercedes dominating F1 for eight years, Lewis Hamilton's amazing, but I
wouldn't say that was the most exciting period of F1, just because one team was so

dominant.

And the thing you see in the America's Cup, think the most exciting races are at the
beginning when everyone's trying to figure out how to use their boat.

And that's when there is that human error.

Whereas when you get down to the end, it's kind of the team that wins a start generally
wins the race because they've learned how to use the boat and probably comes a little bit

less.

You know, there's that excitement in the, the, in the pre-start.

Um, then you kind of lose that, you know, kind of you lose, you lose that excitement
during the actual racing itself.

And my, my advice to like the America's Cup would be to probably have shorter races
because it is all about the start.

That is the most exciting bit.

That is probably the most.

That is where tactics come into play and have more shorter races.

I think that would be better for the viewers at home.

Well, David, I really appreciate your time today.

I think that's probably a great place to end it at.

We'll have information in today's show notes for Artemis Technologies, but is there any
other way you recommend for people to reach out to you or Artemis to learn more about what

your technology can do and kind of help them for any maritime applications they have?

Yeah, you can check out our website.

And then also we have a really good YouTube channel, which has hundreds of videos now
about the technology and the different platforms and some of those cool videos of us

operating in some pretty big seas as well.

So definitely go and check that out.

Great.

We'll make sure to link those, but we'll have to have you again on soon, David, to kind of
see the new boats and technologies that progresses.
