Exclusive Tour of SOLAR Powered 80’ Catamaran - Cruise for FREE! Sunreef 80 Eco Power
Вставка
- Опубліковано 20 чер 2024
- The Sunreef 80 Eco Power, theoretically, has unlimited cruising range and it embraces solar panel technology in a way that no production boat builder has before.
In this in-depth tour and review, Jack Haines, shows you around this extraordinary Sunreef power catamaran and explains how its fascinating drive and energy recuperation systems work.
With 200 square metres of solar panels on board, including some glassed into the topsides of the hulls, and nearly a Megawatt of battery capacity on board, in peak conditions the 80 Eco Power has theoretical unlimited range. It doesn’t have traditional combustion engines but a pair of generators that work as range extenders to charge the batteries and/or run the motors when needed.
True to form with Sunreef, the yacht is completely bespoke so customers can specify the exact layout, cololurscheme and materials of their choosing. The standard four-cabin arrangement is a popular choice but you can sacrifice a guest cabin to grant the owner’s cabin an entire hull.
It’s no surprise on a boat that 80ft long and 40ft wide that the outdoor spaces are immense but having direct access to the foredeck hot tub from the saloon and the sheer size of the flybridge really do stand out.
Yes, there’s a lot of very clever technology here but the 80 Sunreef Eco Power is also a fantastic boat to live on board.
Let us know what you think of the Sunreed 80 Eco Power in the comments below.

Nothing better than watching you in 'enthusiast' mode, Jack. Fascinating vessel, toured with both yours and the team's usual aplomb. I'm still waiting to be disappointed. May be a long wait. Cheers mate
Nothing better? Have you been on the internet before?
Thank you very much for the video. It’s nice to see that yacht. The one in surmountable issue that I have with sunroof is that as nice as some of the interiors are and a spacious as they are, they refuse to give up the fiberglass hull. Every Sunreef Yachts, regardless of how careful they say they are with their infusion process is still a fiberglass yacht with all that. And the bigger they get the far more expensive they get and now we’re asked to spend an insanely huge amount of money for a fiberglass boat. Come on Sunreef, charge a bit more and make it out of aluminum. It’s not a good investment.
Sunreef is a very cool catamaran, it's the king among all catamarans, I got to enjoy this beautiful creation through your channel, I'm also a skipper from Georgia, it's nice to watch these wonders from UA-cam. At least here I am enjoying my dream yacht. I hope I will get a chance to caress my dream yacht in my life, thanks
Many thanks 🙏
The interior is amazing. I love the light colors. Obviously it's in 'charter spec' and is that taupe and white color scheme, but its done very well in here. Very Scandinavian design. 4 cabins though seems kind of odd for a yacht of this size, but given the ga,,ey down design and the crew cabins, it makes sense. Still, with charter spec you would think they would have pushed for 5 cabins or done a cabin with 4 bunk beds in a staggered configuration maybe.
Great boat, Fernando Alonso has a 60ft version on order. Worry would be that solar panels degrade over time and therefore power would drop, that said it's still a great boat but I think that hydrogen engines are the future.
That is a great boat. This will be the future for sure.
Great ship and video!
can see this being very well sold, eco and range, plus get space
Wonderful yacht.
Thank you for doing this review.
When I win the lotto I’m gunna get me one of these!!!! 🥰
HOLY-CRAP!!! 😲😲👍👍 I Could Definitely Live On Board That SOLAR-BEAST For The Rest Of My Life!!! Ifin I Only Had Some $$$-Money... 🤑🤑😜🤣😁😎
I do like this, and the Silent series. I think they be a big player in the future of power yachts, but I think hybrids will also be a big thing as a lot of people will want the security of a fail safe system.
Great video beautiful Catamaran! Love them, I am going to wait a little while until they can get the safety features for the batteries a little bit better, I'd make them into a capsule that can be injected from the boat itself! So if they start a fire, the protection would be fire canisters hitting them first then they would be disconnected and ejected from the boat itself , sure you be without battery but have either a back up system that thrust you forward while the batteries get ejected and the boat safety away from them burning your boat up. Just a thought for the future of designs to come! :) Your welcome need anymore ideas let me know. :)
Fabulous
Not my sort of thing but superb video. 👍❤️🇬🇧
So that 150 range, I assume that is just pure battery storage capacity we are talking about here? Obviously, it chargés during, so it could technically be unlimited depending on your location. Except nights, unless the fuel tanks for the generators are up to it..... How large capasity of fuel does the generators hold?
Correct, the 150nm range is electric only. The generators can be called upon to extend the range when needed.
As a charter vessel this is a great and economic set up. 150 nm is ample for Caribbean 3 day marina to bay and back again.
My kinda boat ❤❤❤
990kw?! Wow. I’d love a review video of the power generation, peak input and output. These will explode in popularity once they got proper sub 20ft beam models out
Can you send one to St Augustine, please. I’ll look forward to it. 😅. Beautiful Cat.
It is a very looking boat.
How long do the photovaltaic pannels last before one has to replace them? Waiting for the Hydrogen Cell powered Boat to come out or "LENR" Cold Fusion actually
Combining the solar with hydrogen should be very doable and I believe they might already doing it. You should be able to make your own hydrogen during the day to sustain energy needs through the night.
So how much can the range extender add with full tanks of fuel?
It’s the future. Imagine 90 pct of the time with no engines or generators on. Heaven.
The % of time the generator is on is irrelevant. What matters is how much fuel is burned. And while it's small, much of its solar is unusable at any time. For example, if you're moored both sides are likely blocked. If you're not, one or both sides of solar panels won't be getting direct sun (if you're facing into or away, both sides won't get direct sun) . It is smart to have a generator that operates intermittently and only at max efficiency to charge a battery bank vs running directly off the generator, for sure. But this isn't nearly as eco as it's being marketed as.
And every ship while moored is already as eco as whatever the shore power is. If that's sustainably generated, then the ship is sustainably operating.
@@zachansen8293 Of if you have a Solar yacht wouldn't you make a point to moor where you get the most sun?
Is there a smaller version of this boat? I don't have enough friends for this.
I believe their eco line starts at 60ft
Seems like it should come with a sail or a hybrid diesel setup. Do people in SF and the Puget Sound boat in non-summer months?
Let's do some maths:
200m^2 of solar, so 40kw per hour (200w per metre @20% efficiency, it won't be anywhere near that!).
990kWh/40=25 hours to charge.
Given you get 5-8 usable hours per day, you're looking at amount a week to charge. Guess that's why they switch on the diesel generator(s) when everyone is sleeping.🤫
That's about a million euros on batteries alone (ballpark figure). It's impressive, but a lot of it is marketing w#nk.
Funfact: They use the same motors as Silent Yachts.
QUESTION: Did they tell you how much she weights? An important figure that's oddly absent.
990kWh is a lot and you won't consume all of that energy in one go. The yacht will be at anchor 90% of the time therefore energy consumption is kept to a minimum (the biggest draw will be from air conditioning) and the battery bank and solar panels will be sufficient to handle the house loads without turning on the generator (40kWp at 20% efficiency = 8kWh x 10hrs of sunlight is 80kWh of energy). In addition, diesel generators are on hand and these can be programmed to automatically turn on when the battery level falls to 75% or 50% but never at 0%. This way the yacht will always have power any time of the day. In case the yacht sails, the 180kW motors do consume a lot of power thus the limited range of 100NM on battery power alone but all the crew have to do is switch on the gensets and the yacht can continue sailing while the batteries are getting charged. Once fully charged the gensets can be turned off and the yacht sails again on battery power alone and the cycle just repeats.
I would say the EXACT opposite. MAke sure the generators are OFF when everyone wants to sleep. If you don't have enough battery at 6pm for the overnight hotel load you run the Generator early. Whole point is you can sleep without the constant hum and vibe of a generator.
That is correct. The crew can run the gensets for an hour or two from 8-10pm then run the hotel loads off the batteries during the night@@redwolfexr
@@ganzonfamilyyou have the wrong Interpretation of kWp and efficiency. A 40kWp solar system gives you at best irradiance 40kW of power so after 10h you have 400kWh. The 20% efficiency are included before. because if you have for example 1000W/sqm irradience on a 2sqm solar panel then it is a 400Wp panel in case of 20% efficiency.
@@OJack0815In that case, it's all the better. If the panels can generate 40KWp, continual sun exposure would be enough to power the hotel loads and the rest can be used to keep the batteries topped up during the day.
That George Town fellow seems to have a lot of boats?
😂
Any model of this size of this brand is of the highest interest. The quality is also remarcable.
does it have regen? like when you harvest the energy from your propulsion. if so i might work harder to get one in the dear future
Whats the range extender, a pack of D cell batteries, how is 150nm limitless
Not to my taste, personally, but great walkthrough Jack and crew!
Same yacht, but a hydroplane. When I'm conquering nature, I don't want to feel ocean waves.
Мечта !!!!
stupendo
Without diesel support you are a sitting duck in Bad weather and a approaching storm, fact☝️
Great tour, nice boat, questionable power train.
I WANT TWO. ONE AS A BACK UP...
That’s a Good Idea….👍
I think these kind of boats will be awesome in about a decade cuz right now currently solar panels only capture 20 to 25% / efficiency. So in another decade or so when solar panels are actually up to 50% efficiency. With a wind turbine for nite time & cloudy,dark days.
How many crew can live onboard during travel
The "electric/solar power" hasn't matured enough to actually replace ICE. So give me a 68/70 Supreme (the best catamaran design, short of a front master cabin like the Aquila 44) with diesels.
What happens when the solar panels hit their end of life? Is the yacht scrapped or does it need to go through a total refit to replace all of those panels? I can't imagine having to have to replace panels embedded in the hull.
My thoughts exactly.
I'd be more concerned about the batteries. If the solar panels completely stopped working (they don't, they just slowly lose efficiency) you still have a diesel electric boat. You can still charge up on shore power, too. But without the batteries, this thing basically doesn't work.
Solar panels are "Solid State" -- they don't really have end-of-life like most electronics. The usual "life" given for panels is when they drop 10% of production and after that they tend to produce that 90% of rated capacity forever.
(hazing and temperature expansion) In real terms they should last 40+ years.
Fernando Alonso ownes one!
Massive beam but might cost in berthing. Solar is great when it can provide meaningful movement but rather than spots of cells, why not make the sides all solar cells from top to bottom and end to end which is both more power and aesthetically nicer as a single color. Same with the other placements, don't do a conventional design and mosaic cells in where they fit but think the entire roof as one continuous panel with no gaps and sharp edges. I would add telescopic roof sections that could be extended for more power, like setting sails. Overhang that provides shade isn't aesthetically unpleasing. A good looking solar cell can have an aesthetic techy look akin to carbon fiber weave and become a nice design element rather than an intrusion. I think the concept has very significant potential. Since most of the time is spent not moving, excess power could be used to create hydrogen that could be run in combustion engines. Basically make endless fuel. With more sophisticated systems it could be made into liquid hydrocarbon fuel for easier storage of large volumes but that's technically much more demanding.
And AI autopilot so it can sail without human supervision makes modest speed travel very civilized and work well.
✨✨👏🏻👏🏻
Thanks Jack! Good luck to this "eco-power" owner..I reckon it's definitely going to be challenge marketing..and selling to others.
These range extenders you mentioned, are they power generators, like a normal diesel generators but without the diesel powered engines? How do that work, or are they top secret?
they are diesel generators. the manufacturer well knows all solar is not reliable.
Yes (diesel is a dirty word🤫).
To the zombiefied state indoctrinated big time and the truth is vilified! VW XL 1 production diesel hybrid at over 244 mpg most owners get over 280 mpg, and that isn't even factoring in bio diesel; thanks to Diesel Gate they stopped production. The best EV can get only 155 mpgE* and that calculation is a bold face lie multiple ways! The real elephant in the room is CO2 reduction equates to less fuel for plants thus less plants thus less O2 and less life. All organics are carbon based. We are currently in the Quaternary ice age in fact...avg temp in Antarctica is -55C... What are the odds they delete my comments...100 to 1?
They are just diesel generators. But the nice thing is that if you have a large battery bank, you can run the generator only at its most efficient speed until the batteries are charged, then turn them off. You don't waste fuel running tiny loads directly off the generator.
Correct, they’re generators.
Surely the OG of free energy for boats is called a 'sail'?
Like your review. Slow down on the edit!!! :)
Roger that 🫡
Does this mean that the future of Yacht charter is much more affordable? Fuel costs are marginal here.
What is the selling price dude?
🍾
I know nothing about boats, but when I see 100-150nm range, I'm puzzled. Where is that limited range feasible?
In Florida and Puget Sound most boats do with sub 200 range. You usually do sub 100 between marinas, often a lot less. The cool part here is you can anchor and just recharge and chill. A dual hull on anchor of this size is comfortable. I can see these boats become very popular for charter in the Caribbean - most of your costs are fuel.
Ha! I'm friends with the owners and I've been on Sol. Amazing, Amazing boat, and the owners are equally amazing people. True heroes of the environment!
It's a good looking boat, but I would have to play around with the layout.(We really do need to get rid of the efficiency cap on publicly available solar panels. Oil companies aren't the boss of other business, why should we allow them to lobby for laws suppressing them? Gates's new yacht has on board hydrogen production power & that just needs to be made available for everyone, everywhere, right now.💅🙄)
Two 360kw electric motors? No wonder it only gets 100 nm at 6 -10 knots range at best! It must have some sizable diesel generators! Yes one in each hull.
Where is the mechanical room ?????
The efficiency of the panels mounted on the hulls is suspect.
What’s the efficiency of the solar panels after 5 minutes underway collecting salt spray? I call BS.
Price is very important, give us a hint next time.
I'm surprised that no one has designed a dynamo that uses the drive shaft rotation to recharge the batteries.
An ocean doesn't float downhill 😂
@@dagg497 You're thinking of Hydro power bro, a Dynamo is totally different.
So, a multi million dollar gin palace that has a range of 100nm at 6 knots. And this is the future. And it's environmental impact is?
Ever since Silent Yachts proved the concept there have been multiple others copying them years later with exactly the same product: Solar powered catamaran yachts.
HOW MUCH?
9m
150 nautical miles on a full charge is not very far.
It needs a mast and a sail to give it range and speed. When you can store the same amount of energy kg for kg in a battery the world will be a different place.
batteries don't need the same energy density as gas because they are much more efficient at converting back to electricity than a combustion engine. But it's still way less even after conversion % applied.
They do offer a sailing version. Plenty of buyers don’t want the hassle of running a sailing boat and the compromises on deck space.
If only there was a way of harnessing nature to power a boat…..
Generators are engines.
My Ford super duty has a diesel "range extender" under the hood also.🤦
I wonder how this boat performs in difficult weather. The setup and interior seems to me more on the „sitting in the harbour“-side.
934HP 150 NM range and at 8.5 million? Hell no! Anyone try electrolysis to really extend the range on a gas engine? Or what about a zero point engine powered yacht?
Abroad in japans brother
Silent yacht is far better🤗
lol
then why are they going bankrupt?
its a beautiful boat but the dishonesty of the marketing must be called out. "no engines, only electric motors and 'range extenders'". this utter kaku and perfectly illustrates the falsity of this "green" agenda. the so-called "range extenders" are generators, i.e. diesel fired engines. and they are not there to "simply" or "only" anything. they are there because the builders damn well know that 100 percent solar is unreliable. the diesel generators, in contrast, are very reliable. this sort of nonsense has to be stopped and if YachtBuyer wants to maintain its integrity it must be honest about these facts and not gloss them over with the manufacturers marketing schemes.
This is the first review I've seen Jack do
that seems to have abandoned his
informal, unabashed, no holds bared
treatment, in a walk-through/review.
Eerily reminiscent of a yacht broker
'review' .
Invitations to film onboard are rare and not handed out to wrench throwers. Jack does a fantastic job of framing his criticism very carefully. or will bless accurate comments with a like. Acid mouths like Esysman hardly get onto vessels of this size.
@@wildcountry.
Strawman reply, to the OP I assume.
Who is 'Esysman'.
Do you think anyone will see your
comment as addressing the OP
contextually?
Yeah, to completely run the boat on solar energy alone, meaning generate enough energy for not only the operation of the boat but, enough excess energy to charge a battery for use at night, the solar array would need to be 3 to 4 times that of the boat’s total footprint. I wouldn’t call it a “green agenda” though, as the technology already exists where land based solar farms installed in appropriately sunny locations provide more than sufficient energy generation to both the grid as well as to battery farms that collect excess energy generated from the solar panels for use at night, providing reliable and truly round the clock solar generated electricity. Tesla Energy is doing this and there are already installations like this around the world in Hawaii and Australia. This is just a company trying to capitalize on the increased interest in moving towards more green, renewable and environmentally friendly ways of generating electricity and as a company that designs and builds some of the most polluting things on the planet, they can claim that they are seriously moving towards green renewable technologies for their boats when, in reality, the technology isn’t yet sufficiently developed nor advanced enough to fully power a ship of this size with only photovoltaic solar panels. I will give them one thing, with their range extenders, it is technically more efficient to burn fuel to generate electricity and use that electricity to power an electric motor for driving a propeller, than it is to burn that same fuel to power a mechanical drivetrain. Yeah, it is definitely still a fuel burning engine but, it is technically a more efficient way of extracting energy from a fossil fuel. All misleading marketing aside, at least they are doing something to build a cleaner running Yacht.
@@bikersoncalli actually think @wildcountry at least has a point. I imagine a part of the agreement for being allowed to film on the Yacht was that the power generation and propulsion systems were to be addressed in a certain way as to sufficiently explain their functioning and to perhaps do so in a more generous manner and portraying things in a good light, choosing to omit some of the downsides or impracticalities of this sort of solar electric / diesel generator hybrid drive. Is that necessarily a bad thing, possibly, as it could come off as a bit dishonest as to leave out certain information that highlights the limitations of the technology could potentially lessen viewer trust in this outlet.
🥲 SIMPLY BEAUTIFUL YACHT
W😳W FLAWLESS CREATION👙🍾👙🥂👙🥃
"It has no engines....and a range extender". A range extender is a generator which is an engine. It's not a direct propulsion engine but it's sucking down fossil fuels. Hiding it behind a different name is disingenuous. It turns fossil fuel into propulsion for any reasonably long trip.
It's still a cool boat, but greenwashing it like this just makes the whole thing feel bad. Just be honest about it and that we're in a cool transitionary time in boat building and it's cool. But this video wasn't cool.
l love fossil fuel power, but I think you're right about
the 'disingenuous' aspect coming out of the builder.

Are you restricted to
grunts and nods?
And how does your false-narrative
justify a lie?
@@bikersoncall If you want you can live on a boat like that for years and not use any diesel. Its totally OPTIONAL to use fuel.
You just have to adapt your life to the BOAT DESIGN and not try to force the boat into the role of a cruiser yacht.
I watched someone on a Silent Yacht charter and they did all this motoring around so had to run the generator a lot. If you only travel 20-60 miles a day instead you will never ever run out of solar.
That is what all the naysayers in the comments are totally ignoring. It is designed for a VERY SPECIFIC niche. If you force it to perform "like" a normal non-solar yacht then you are gonna need to burn fuel like one.
If you adapt to living in a 100 mile radius in a floating condo and use "free" mooring bouys you can live totally free of electric, fuel and slip fees. That was its target, and you would not need a crew for that either. That is why the smaller Silents are so popular - they have low hotel loads compared to their total power production.
The greenwashing is that people who KNOW they want a high speed long range cruising yacht and buy this instead.
@@redwolfexr
Good points. As a Niche boat
that does make perfect sense,
using it in a manor not mentioned
in this review. The op was still
accurate imv, given the content
of the review. Those with a budget
for this yacht (my guess) are
not going to buy this as a
'boon-dock' live aboard,
I think 'they buy this' as a
novelty item, a beautiful one
at that.
Buying this yacht probably
means the owner already
has a Citation , more
than one vacation villa,
as well as a 10k+ sq ft
home base.
Hydrogen is king for boats as they can produce their own fuel with electricity from the solar panels. 150 miles is only good for day trips.
Do you draw much when you speak all that obsequious flattery?
Range extenders?. Isn't that a engine that uses fuel. 150 miles isn't enough so you have to burn fuel lol
The range is laughable 😂
Falls right in line with biden's economic plan, build back better, greener, good luck with that.
The maintenance on this boat alone would cost you a small fortune. Solar panel replacement from damages, not to mention the batteries required and the replacement cost of such.
6kts ?
🤣
I was expecting this boat having unlimited range then i realised solar is garbage
Thank you for featuring another solar powered electric boat. Things are necessarily changing in the world and yachts with enormous fossil fuel consumption are just not the way to go forward in a future of this world.
GREAT!!! Better watch it now because in 5 years this Cat will look like SH#T as it will be literally falling apart. I started in solar in the 1980's and cannot list in 10 FULL pages all the reasons this will NOT work longer than just a few years without MAJOR investments to FIX this boat CONSTANTLY. REQUIREMENT; more money than brains!!!
The only thing these solar panels are good for when you are docked or on anchor. WHICH IS AMAZING BY ITSELF. Stop trying to lie to people that such a boat can run on solar. The energy you can get from solar is just about enough to keep the air conditioning on. These "solar" boats run on diesel.
Lovely yacht if you are just island hopping say in the Bahamas but useless for anything long haul. In addition to that the batteries will cost a fortune to replace as will the solar panels that degrade over time. Solar powered yachts are not the way forward with current technology.
80' boat with 100+ nm range.. who would buy this piece of junk? can't even imagine how long it will take to be fully recharged.
What is a normal NR for a yacht this size?
@@nonyabusiness9747 on a cartamaran this size anywhere from 1500-3000 nm.
Let's do some maths:
200m^2 of solar, so 40kw per hour (200w per metre @20% efficiency, it won't be anywhere near that!).
990kWh/40=25 hours.
Yeah, that will take a while to charge given you get 5-8 usable hours per day. That's why they switch on the diesel generator(s) when everyone is sleeping.🤫
Oddly, there's no mention of the weight, even on their website (2400 to 6000 litres of fuel). Merely listing the engine power doesn't give an indication of range/ performance.🤔
Funfact: They use the same motors as Silent Yachts.
It has diesel generators (cleverly called "range extenders" so you don't say "diesel") so it can do whatever.
Its another great day for rich people. Thumbs down. Do not recommend channel.
There is no such thing as a free lunch. This is a toy. Its only good for coastal cruising. N9 serious sailor would use this vessel for a LA to Australia cruise. It won't make it.
A virtue signaling gin palace ..
I agree , but don't get the
'gin palace' part. shrugs..
Lovely boat, stupid idea, if you want to spend a fortune and be this limited good for you, go virtue signal to your hearts content, maybe one day the tech will allow for this, that day isn't now, not even close, i doubt electric power is the future for boating, i'd imagine more likely it'll be hydrogen.
That boat would be great if you are island hopping or not in a hurry. You travel a few hours, then stop and charge. It is more of a house boat than something for long range travel.
Maybe we will see this electric yacht being towed by a diesel powered boat in the future because it got stuck in the middle of the ocean 😂
Only 150 nm range?
What?
In electric mode, the range extenders (generators) boost range significantly.
@@Yachtbuyer yeah I heard its transatlantic but then again that must be in walking pace.
It is for most yachts! You ain't crossing the Atlantic at high speed.
@@Yachtbuyer Thats true. However crossing that body of water at 10kph lol, you start the journey young and when you are there you are a retired citizen.
