I bet a dis-masted sailboat with a small cabin and a centerboard keel would be PERFECT for your next boat project. Displacement hull, WAY more freeboard for mounting solar panels, a cabin to sleep in and get away from the sun and waves...I think sailboats are a legit use-case for solar propulsion, so it would probably interest sailing nerds too.

[@Morphior]

Oh, absolutely. That’d be sick. I have been thinking about doing exactly that, just not with a dismasted sailboat because I love sailing. But most sailboats that aren’t tiny have a motor anyway, and having that be electric would be sick. But it’d be pretty expensive - boats aren’t cheap and all the electronics and motors and stuff probably aren’t either.

[@neovo903]

Only issue would be sourcing an electric motor large / powerful enough for such a large boat (in comparison)

[@Savanna_WCUE]

Keep the mast and have solar sails. Solar panels that you can raise up and rotate to catch rays and wind

[@neovo903]

And that you'd likely be using higher voltages and requiring HV cables and electronics. I'm not sure how much equipment would carry over to that project.

[@silenterection]

So much work and you could just use sails 😂

[@fonkbadonk5370]

What totally blows my mind is, that we're at a point where you can PRINT large parts of a solar dinky, live on it for days, have it auto-pilot really well, have a video editing station on board, and being able to make fly-by and overhead footage ALL BY YOURSELF, and all this time be reasonably comfy. And it's completely sun-driven to boot. Just crazy.

I definitely thing a more efficient hull would add some serious range, and you've still got the columbia river trip you didn't finish this time :-)

[@TharzZzDunN]

Exactly why I suggested a trimaran hull, he was bounced around pretty bad in the wake and waves. Some decent shade for the batteries would help as well.

[@akumabito2008]

The solar panel frame seems a little delicate. Maybe you could wrap a pool noodle around it? If it catches a wave, it should have ample buouyancy to glide over the top, preventing 'scooping damage'.

I agree, if he increased the Iyy it would make it less suspectable to damage from bending in the y axis as well.

Create a low cover for the front of the boat that would keep your electronics out of the sun without blocking the solar panels yet allow wind to pass underneath. This would greatly help with overheating. Maybe even one for the back as well. Use light aluminum frame with cloth streched to keep rigidity. Leave the middle areas open for seating and such.

[@badsamaritan8223]

I feel like a trimaran is the ideal design for a solar boat. You've got large flat space between the outer pontoons and the center hull, and the pontoons keep the solar panels supported properly. The narrow hulls allow the boat to move through the water with little resistance, and they keep the boat super stable.

[@RhynoD2]

I wonder how difficult it would be to automate the speed based on the fullness of the batteries: eg, once the batteries are fully, increase speed to match what the solar panels are providing, and then decrease speed as the sun starts to go down. And theoretically, you could have a servo drop anchor when the batteries drop to a set point so you could go to sleep and let the boat just keep cruising until the batteries go down. Probably not a good idea for safety but it's a neat idea.

[@faustinpippin9208]

really easy, you could even make this "analog"

[@mattmarzula]

No. It is not a good idea. It's never a good idea to let anything make the decisions for travel on water, ground, or in the air. Short of space travel, you want your decisions to be deliberate with a man in the loop. It would also be a useless addition. The energy you would route to the motors would be better served charging batteries. Speed is less a necessity than stamina. Also, a cloud or shadow would halt the motor and then it would spin up with full sun. This would cause more wear and tear to the working parts from constant declaration and acceleration as opposed to a steady speed.

[@haphazard1342]

The only issue is efficiency. Motor current increases faster than boat speed. This is fine if all of your energy is "excess", but the efficiency is better is low speeds. Also, the power generation follows a curve. I expect that the most efficient approach is somewhat different. You want maximum charging to take place during maximum solar collection, because that energy can then power you overnight while running as a lower and more efficient speed. Basically, the most efficient approach will have the batteries drained down to almost zero right at the start of the day, just as there is enough sun to completely power the motors.

[@haphazard1342]

Basically, for every day you want your total generation (in this case, idealized total generation for his 1000W system in Seattle in July is probably around 4.5kW) to equal your total consumption. If he runs for 16h/day, and loses 0.5kW to inefficiency, then that gives 250W for motors during running conditions.

[@ionstorm66]

​@@mattmarzulathe boat already drives 90% of the time on autopilot. It's already controlling the throttle to keep speed constant. Ramping the throttle up and down to keep charging the batteries due to variable solar power isn't a huge jump.

[@AncientEgyptArchitecture]

In terms of hull efficiency you may want to consider a small catamaran, say 16-20 foot, and put a rigid roof on it to mount the solar panels and keep you and the gizmos cool. Further propulsion efficiencies might be gained from putting a printed duct/cowl around your props and using a prop form optimized for that.

[@murraymadness4674]

Exactly what I would suggest and planned to build, I have a Pacific Cat 19, very efficient. I would also suggesting he build a rim-driven prop, which is what I wanted to do. I was hoping he would do at least one boat chanty song like his other video on a solar powered kayak.

[@glumpfi]

This is one of the most satisfying and relaxing videos of the year, thanks for sharing your trip :) The fact that your boat has an autopilot makes it even more satisfying to watch! Maybe for the next trip you could add a solar roof, so you have more protection from rain and sun. You could also lift up the side solar panels to roof level, so they don't hit the water and can be used as side walls in heavy rain

[@dandahermitseals5582]

And by raising the CG you make the boat unstable. Keep a low CG. I'm a 60 year designer and builder of boats and light aircraft. Dandahermit

[@dandahermitseals5582]

Could have tilted the panels to form an a frame shelter. Dandahermit

[@glumpfi]

@@dandahermitseals5582 That's an important point, didn't think of that. But i'm not sure if the destabilisation is so much worse than being exposed to sunlight and rain. The used panels are flexible and lightweight, maybe it would be possible to compensate the weight with weights on bottom?

[@ke2delight]

If you had a roof system to protect yourself from the elements you could add another 3-4 solar panels and have unlimited energy even if you go faster. Just sayin…

[@joegerkrep7727]

That would destabilize his small boat way too much

[@acidtalons]

[@DaleStLouis-xb5mx]

The flat ribbon of water is due to a subtle current. Currents are strange on dam-bounded lakes where you wouldn't expect. The old river channel is deeper, and that's just one thing that can cause subtle currents to do strange things. So, the wind is blowing just hard enough to kick up small waves, everywhere except where the current is already moving at that speed. OR, opposite, sometimes the wind blows the the other way, lightly, and it only scrapes up waves where the current is against it. I used to fish for bottom feeding catfish and knowing where the old channel was, helped locate them sometimes.

Fun video! Whilst I don't think there's much to be gotten out of toroidal props, I think your power absorption issue is related to the arrangement of your blades. I would suggest having another go with your design improvements but using angularly displaced blade pairs to reduce pressure/interference drag, and reducing that 9 degrees on the joining wall as that is acting like a large paddle.

Pontoons are stable, but they tend to be pretty drag heavy. Some of them come with ready made "walls" and roof which could mount solar panels. You could do a decent clip with enough panels and large enough engines and large enough battery. The battery weight would probably be the killer. If you don't mind not pulling a water-skier the whole time, you can set up something that mostly runs on panels and save some battery weight.

[@fatsolutions]

Brilliant work mate, living for 72 hours in such a small boat is an epic mission in itself but building all of the power systems yourself is next level.

You should do the math for your speed and RPM range to find the optimal pitch angle for your props - my suspicion is that it's way, way finer (ie, smaller bite) than anything you've been using. Compare the boat speed to an e-foil's speed, reducing pitch proportionally should get you in the ballpark. PS the freeze dried chicken coconut curry will blow your mind

[@MrSweetHart6976]

We definitely need to see more videos like this 👍 But I would make your boat more into a "house boat" and keep testing new prop designs to develop the most efficient prop. Plus maybe adding a small wind generator might not create too much drag to make it worth it?

Yes it's very likely only the rear part of your shaft-casing. There was likely a large periodic separation bubble before that caused the vibrations. Making the rear end come together over a larger distance (think truck vs sedan) decreases the chance for separation and thereby periodic flow patterns. It should also increase efficiency a bit. Although the motor shaft probably doesn't contribute too much to the overall drag.

[@stevenholton438]

You did really great man! Part of boating , you will find, is becoming acquainted with that feeling of being remote and entirely depending on yourself far from anywhere!

[@dr_jaymz]

I put this on as I was going to bed and found the whole thing very relaxing. The whole area is so different to where I live and a unique perspective which seems a bit surreal. The vibration from the blades is similar to that experienced with pusher prop aircraft and wind turbines but in reverse. There is an area in the swept area where of the blade where the oncoming fluid is a different speed or otherwise disturbed. What you did was to try and smooth that out and yes it will only make a difference at the back. This is because the fluid stays laminar when you are squeezing (high pressure) it at the front but when its returning to fill the void (low pressure) it likes to get chaotic. This is fairly intuitive way to think of it. The toroidal props are a bit of a minefield. They are effectively 6 bladed prop with extra drag at the tip, they will never be more efficient because the rear blade is running in the wake of the front blade and the front blade is affected by the rear blade which changes its effective AOA. I wouldn't try to work it out. The less blades the better, you can even have 1 blade and a counterweight. You only need more blades if you struggle to absorb the power at a sensible RPM. 3 seems to be the happy point. I wonder how much better the solar works when tracking the sun?

I was thinking that the solution to the solar panels getting bashed might be simply mounting them higher, which could also afford some shade from the sun in the boat. However, I'd be concerned about them catching wind (i.e. trying to become wings) the higher they get off the water. I'm wondering if it would be possible to take a cue from the ground effect stuff you've done and add some "wings" to which you'd mount the solar arrays, which could also be used to support outriggers (fiberglass & foam construction would make sense) - that combined with a decent canoe hull might result in a more efficient hull design. Don't know, not an expert, just a thought.

This is the first video I've seen from your channel and this was super fascinating! I'd totally enjoy this kind of project! I did wonder if you'd considered making a roof assembly for the panels so you could have shade while also keeping the panels from getting caught in the waves.

Too top-heavy prob

Great video! Regarding the toroidal props: The Sharrow propellers are laid out for ICEs operting in the 2-3000 rpm range for 150+ Horses and god knows what kind of torque ranges. Since you are using electric motors to turn your props, you have a nearly constant, but narrower torque range. You may need to design some sort of planetary gearbox to drive the toroidal props at higher speeds, OR, modify the layout, for lower RPMs and higher AOA in this case with a step-down gearbox.

I really enjoyed that, dude. Thank you for showing us the beauty of the pacific northwest and sharing all the nerdy ins and outs of your boat, its very cool! I also liked the electricity math for the dam, mindblowing what humans can achieve isn't it?

[@ke2delight]

What would happen if you do two attachments for balance like a trimaran? It will be safer and the waves will not be able to tip you over.

Another question, if build a roof for your small boat, with fold up panels and panels in the center, would that make it too top heavy? If not, that would keep the panels well out of the water and provide shade. At night, folding the side panels down would provide some shelter from weather. :D

[@rockyrocker23]

same idea for me with the whole roof being solar with the two folding panels he has hinged to the bottom and can act as a wall on the sunny side, but then its probably impossible to tow at speed without tons of reinforcement

That funny looking structure on the shore looks like an old sawmill.😊

[@mx.notyourbusiness8693]

Really enjoying your boat adventures. I'd love to do something like that! Nice area you live at, too! Love all the cliffs and trees and beaches, it looks wild and largely untouched. Greetings out of my small 1 room apartment in a big city in Germany 😅

I'm glad to see you're starting to take your personal sun exposure a bit more seriously (the neck/face covering, etc). As someone who has already gone through skin cancer I'd been a bit horrified at some of your previous all-day trips - sun lotion can only do so much. In a previous vid you mentioned that you'd discounted a roof style array but that would really help surely? Anyway, stay safe and don't forget to consider yourself when you are optimising your designs.

Question, guys. Now, putting a magnifying glass on solar panels. Will this improve their performance on days when the sun is not bright or if there are some clouds? Will it make their performance better or are they limited to a specific production?

[@retbucket3119]

The magnifying glass would need to be larger than the solar panels to actually catch more light. Although the glass itself might also block some of the light

[@economicurtis]

What if the solar panel lit lights pointed at the solar panels?
