This is the Stealth 40 (?) built in Thailand. I considered this boat as a personal build but unfortunately, the hulls are too narrow for an inboard diesel running (WVO) and tankage for extended cruising. She's an awesome boat, thanks for doing this build and pushing the limits of what is possible. I do disagree with Mr. McGettigan that Hydrogen will save the day for marine applications. The cost to manufacture "Green" hydrogen is approx 7x the cost of generating renewable electricity. Hydrogen atoms are so small that it is nearly impossible to store them onboard in quantity safely. Good hydrogen efficiency requires an electric drivetrain and batteries, so additional added complexity and weight. We will soon see a 50% improvement in energy density for Lithium battery technology (per Elon) so I believe boat design will need to work within those parameters in the near term. Great video, thank you!
direct injection of hydrogen and Oxygen (HHO) into the engine is much cheaper and allows for near 100% fuel burn, in diesel this would equate to double the range efficiency. Could also be used in Gasoline engines, like toyota or Mazda Hydrogen injected engines. Hydrogen stored as water then split just before injection is easy. Done several of my personal vehicles. just have to adjust O2 sensors to allow the most efficient burn. Fuel cells sound cool, but simple combustion still works great. Start generators on fuel then as they create the HHO they use far less diesel.
@@makeb-leafproductions2403 Can you modify a common rail diesel to use an HHO system? What are the power input costs associated with splitting to H? You are claiming from first-hand experience that you DOUBLE the efficiency of a diesel engine? A 2mpg diesel boat suddenly gets 4 mpg?
@@jon2016 did it with my dodge ram cummins, just build the hho maker (many youtube videos), barely any power draw, feed through bubbler then into intake. The O2 sensors on most modern engines will be the issue, as it will detect too much o2 and increase fuel. better to use older none computerized engines. the HHO simply burns everything more efficiently, I'm not running it all on HHO, just making the fuel waste out the tail pipe far less. imagine burning all of your fuel. however Mazda had a gasoline engine that could run on hydrogen, toyota engine too that is on the current test ship "energy observer"
@@jon2016 The ship called energy observer has toyota engines that run on Hydrogen it makes from solar and some wind. these engines are generators and whole boat has electric propulsion. batteries are too heavy, compared to hydrogen, so they just make it to fill a couple tanks onboard. Hydrogen can also replace propane stove gas. So it can save on that as well. hydrogen becomes the storage medium for all that solar and wind.
Not a fan of electric for boats but well done for a clever approach. Still if you want to go far or fast diesel is your friend. You can’t beat energy density. Imagine the same vessel with a couple of 75hp common rail diesels. Go for miles at a few litres per hour each
@morri03 How big? How fast, What range, - and why added complexity of "common rail injection"? and the noise /vibration of heavy diesels? I had a pair of Kubota 3 cylinder diesels (could run using filtered coconut oil) I de-rated to 10hp (noise and vibration) and giving 6 knots and burning 1 litre/nautical mile, both engines running to drive the propellers at 1000rpm. (pushing my catamaran 40ft and weighing a bit more than 4000kg)
Set your speed right and manage your energy and a solar boat will run forever. You can run out of diesel but not light. Don't forget that hand in hand with energy density goes efficiency. A diesel might only be 33% efficient in converting chemical energy to propeller thrust so actually 67% of that higher energy density you refer to is wasted as heat.
@@marviwilson1853 maybe watch the video. The owner explains that isn’t possible. Let’s do some quick math. The boat draws 10kW/h at 8 knots so it’s flat at 36M. The 2kW solar panels might be 1kW average (the 2 is the max on a sunny day at noon) so it’s a 10 hour wait effort you can go another 8M and be flat again. That’s why it has 2 diesel generators. You are right about efficiency but it doesn’t matter when a kg of diesel has a 100x more energy than a kg of battery.
@@morri03 My thinking was that you cruise at 3-4Kts and draw maybe 1.5Kw. You also fit 100KwHr batteries and have a 5Kw array. Now you have continuous 4Kt cruising. Re-cycled 2nd use EV batteries make that a cheap option. Your 100x energy density number is way to high. 1 Kg of diesel contains 45.6 Mega Joules of energy. Lithium ion batteries store about 0.875 Mega Joules per Kg. A difference of 52 times. If we take a diesel engine as being only 32% efficient then that diesel energy density drops to 14.59 Mega Joules per Kg so now only 17 times more. Diesel energy density is fixed but as we all know battery technology is in full development. 1.6 Mega Joule per Kg batteries are already being tested. Now we are down to a factor of 8 different. Take into account that you can "refuel" your batteries from sunshine while at sea, (you can't do that with diesel) and the practical numbers become even more convincing. Then off course there is "the future" and who knows what advances in electrical energy storage that will bring. At present diesel is only any good at blasting around the sea at highly inefficient speeds. Of use to many off course.
I have a need to regularly travel significant distances around the islands of the SW Pacific Ocean. I envisage a vessel of some 48ft LOA and a beam overall near 24 ft, riding on lulls of some waterline beam of 3 ft or finer, and about 3ft clearance to the underside of the bridge-deck for "wave clearance". All in "displacement mode" and hopefully achieving near 300 nautical miles range in 12 hours. Now things become very difficult to explain (zero point energy) and further out to - "levitation and higher velocities around twice that of sound". I am aware of detailed drawings of several historical craft that achieve that and more. I would appreciate any assistance in materials (and weight penalty / strength) I have already built a vessel using Balsa cored glassed panels (Duflex) and was poisoned (by exposure I presume to epoxy hardener at the mixing stage) and I am now sensitive to those chemicals. I am aware of construction processes that utilise 3-D printing at a molecular precision device in a low gravity environment of almost any base material. Private discussion (text) would be appreciated and assistance in drawings and appropriate scantlings for aluminium hulls.
Tesla Battery storage is getting way more efficient and cost-effective that's a fact for those who want to do their homework, If you are getting battery storage from anywhere else other than tesla you are getting it from the Wrong Battery storage Dealer and wasting your Money Before any haters try and say otherwise Do some homework First!
They have low watt flexible panels, partially covered, and not fully covering the roof. No wonder they can’t get enough power to continuously run on. Bad install. His hydrogen and lithium take is wrong as well. This guy is an amateur.

A mast , not a big one , to support one or two sails as backup will make it more efficient ; I think . Otherwise this is a very nice boat . 😊👍👍👍🙂
Hybrid propulsion will become the standard on new boats but they will have much larger gensets. Most boaters go less than 20Nm to their local spot.
max range in a day?
I want it! What’s the price? I guess it’s the only one built
i like it!!!

Thanks man, complete novice here, survived a death bed now I want a Coastal hugger for the rough south African summers to fish the rest of my days.
Tesla are mainly buying cells from CATL and BYD now apart from the 4680. But agree energy density and < cost are improving.
@@greenmatt1981 CATL just hit 500wh/kg. Still, there's a long way to go to match the 30x energy density of diesel to lithium.
