Heya! I have some experience with this sort of thing - the liquid level sensor corroded because of the DC voltage applied, which caused the corrosion. There are some techniques to mitigate this: you can either apply the voltage for a brief time for the measurement once every number of seconds to extend lifetime or apply alternating polarities with each measurement to reverse the electrochemical effects. Either way, and I say this with the utmost respect, you need to up your waterproofing game. It sorta hurts to see so many of your projects scuttled by water ingress when your waterproofing amounts to just silicone, which sorta sucks for this. I recommend you check out waterproof cable glands with PE tubing to carry conductors and some more design considerations for things like acrylic windows like labyrinth seals and compression of silicone/other seals POST-cure. Love your stuff, hate to see it fail due to the world's greatest chemical :)

From my experience with RC boats, once it's on there, it's not coming off until you remove it manually. At this scale, every bit of weed is the equivalent of 10 feet of rope to a full size boat. I've actually ripped a rudder off just from vegetation that got somehow looped around it and wound up by the prop.

I’m always left speechless at just how creative and technically skilled this guy is. He’s always building the coolest stuff!

Other people making autonomous ships and sailing along yours, competing for efficiency, range, who gets to the finish first, etc I would be down and I'm sure others would be too

I have to say. This is one of my favourite KZread channels. I really enjoyed the last boat rides. Such a relaxed vibe! 10/10

nice bit of aquatic R&D there! Float switch for the bilge pump might work better?

I love how much time you put in to recording your voice-over. Extremely concise.

Those low slow-mo shots look epic! It is an amazingly small boat for wakeboarding behind and it seems like a very utilitarian boat overall.

For these autonomous boat projects, I wonder how a paddle wheel might fair. There would definitely be a large loss of efficiency compared to a prop, but with hopefully less trouble from seaweed you might see an overall performance boost. Seaweed could still get caught but would be more likely to fall free since the point of rotation is outside the water, and a comb could be made to grab hanging seaweed as the paddle left the water if rotation is fast enough. No clue if the overall performance would be better or worse but might be worth at least investigating. Also, would be interesting to combine such an old propulsion method with the modern aspects of being electrically/solar driven and autonomous.

@michiganengineer8621

I'd go with a side wheel design myself in this case. Driving two (or more) side paddle wheels would be less complicated than a stern-wheel (unless you mount the electric motor outside the hull). Differential steering would make a lot of sense for a "small" autonomous rather than hull penetrations for the rudders.

4:49 Andromeda Strain scene where the surgeon cuts the country doc's deceased body and sand pours away. 7:16 you could add two extra flotation tanks to the left and right of the motor directly on the transom. Basically you take some foam blocks, cover them in fiberglass (making sure they fit the shape of the transom) and you screw them in place. FIY you should over drill all the holes you've made and fill them with resin. Water will get inside the foam layer and you'll trash the boat if you skip this step. edit 3: to make it clear, the resin is in there to create a barrier between the foam and the screw.

In yachting you have propcutters for if you get a line caught in the prop. Maybe a possibility for the seaweed?

I love watching autonomous projects. My favourite one was the banana slug because I really liked the single hull design.

I love your autonomous boat videos so much! They're by far my favorite. Can't wait to see what you try to fix the seaweed problem!

okay so there seems to be some confusion on what "plaining" is , it is not when the stern wash separates from the transom , it is when the boat lifts onto the surface of the water or ever so slightly below it , the boat will give a very distinctive feeling when it does this , the front will go from pointing upwards to leveling off once the boat has reached enough speed to overcome the drag of the water against the hull , plaining doesnt usually happen until around 12mph

Did you add flyback diodes accross the relay? Even if the uC can handle the voltage and current needed to activate the relay, an inductive load like that will produce a large flyback voltage when you shut it off, all that stored magnetic energy needs to go somewhere and if you dont give it a path like a diode it will just keep upping the voltage until it shorts something out.

Super fun - I took a lot of inspiration from your videos and made my own boat. Currently changing my own from inav with a standard analog vtx to ardupilot with openipc as the video control link.

Thanks for the video, always enjoy watching!

When thinking about boats hulls that work under low displacement you should look into a rowboat with a “shallop” or “double shallop”design. They have sweeping lines that come down to a V shaped bottom. They work amazing at low speeds and are commonly used as sailing dhingys. I’ve seen them be incredibly stable even at low speeds like 2 or 3 knots. An electric motor on one would work amazingly as they do so well at low speeds

the drag of the water really helps with the 3d printed parts when in rotation because they are being compressed instead of stretched by the g forces from spinning

I love the “Place where the aircraft carriers are”. Better known as Bremerton and Port Orchard the body of water is the Sinclair Inlet. I love sailing in that area but where the 3 channels meet the winds get all sorts of confused and it makes for an interesting sail.

For alternative propulsion, you can combine both wind and water : For wind, there is the classic sail, but there is also the amazing Kite, which could make a great project, a self launching and recovering Kite, in fact, you could even generate electricity with Kite. There are the : *Pulled by wind then retrieve through gliding. *Pulled by wind then retrieve through flag position. *Figure eight. *Spin on itself. Ways of making electricity from a Kite, all pull the craft while unwinding the cables if it has enough resistance and both the figure eight and spin method allow to still get propulsion during retrieval, but they are harder to control, while the gliding method (mostly with a self/neutral stabilized sail) is the easiest to control with simple electronic. As for the water propulsion, you can combine multiple types, but some are almost seaweed proof, like the FIN'X or the more typical undulating fin solution, which isn't that hard to make with as it work with a single crackshaft, as here you only need to control longitudinal thrust, unlike all those submersibles. One thing I thought about would be to make a Trimaran hull design, but with the side hull on hinges with a simple breaking/locking mechanism, they would use the wave movements to generate electricity, the same way a "sea snake generator" do works, except it would serve both as a "suspension" to absorb waves impacts and generator. A full bridge rectifier would allow any movement direction to always produce the same polarity, with a simple angle limiter and dampener, it could probably work well. As for the water problem, you could have two hulls, one inside the other, the pump intake and water detector (which could be homemade in 316 stainless steel or other corrosion resistant conductors as a series of close enough "pins" to detect non-salt water's conductivity) and a water pump type which can run dry, such as a peristaltic one which are not that hard to homemade, since the mechanism isn't touching the water, any small particles won't cause issues inside it, with a timer that enable it for multiple seconds after the water detector is triggered, so the movements of the boat won't make it "miss" the water. And waterproof the electronic with a simple hot glue gun so only the wires and possibly radiators (as it may overheat inside that) are going through it, same for the "inner" hull, which can be totally sealed off using a lead that contain the same hot glue (so you don't have to engineer a perfect fit lit with joints), bonus if you include a "hatch" with all the connectors for recharging batteries or connecting microcontrollers.

I truly enjoy the combination of science and adventure that your episodes display, thanks ☮️

Your videos are always a treat. Wish to some day to be able to design the same kind of stuff.

I wonder if there are any propeller designs that are designed to minimize string tagling or trapping weeds. These designs are probably not energy efficient, but at least you won't have to worry about the propeller getting stuck.

I suggest to move the fuel tank forward of the console for better balance. Even mounted under your forward wooden bench would help loads with the stern water problems. Amazing work as always, keep it up!

I'm hesitant to get too close cuz it's an autonomous boat, I feel like i just need to let it do its thing. You know, keep my distance. "I don't want to be a helicopter parent" 😂😂😂

Those water sensors corrode because powering them makes them act like a battery. They last much longer if you only switch the power on for a moment every now and then. The other way to detect water is to run the pump and measure how much power it draws. It takes more power to pump water than air.

here before rctestflight creates a yacht in a couple of years, fully autonomous and solar-powered, it becomes known as the "drone hub" for all local pizza deliveries

Very cool project, and a good attempt! For a more robust liquid level sensor, and something that isn't susceptible to corrosion, perhaps a switch connected to a small float would be better? Like in a toilet tank, but with an electronic switch on the end of the float.

To stop the sensor corrosion you need sacrificial anodes. Wooden boats with electrical systems on board need them so that the nails holding the boat together don't corrode away and allow the boat to fall apart. If you're not familiar with this concept, you've got some research to do. #boat #zincs #electrolysis #corrosion

Honestly, your manned boat content is my favorite. All the videos are great but I can't wait to see what you do next with the boat or a new one

On racing sailboats there is occaisionally an option for a weed-cutter keel or a rudder. Basically a knife edge that cuts through seaweed. A couple razor blades upstream of your prop will get the job done. I think I've even seen it on rc sailboats.

Great project and mission. I even enjoy your battle with water proofing/leaks/humidity attacking your electronics. All good fun :)

Just a heads up, going slow and close to seal covered bouys, can be risky. A friend lost his boat when a 250kg bull that couldn't get space on the bouy, took the easy option and jumped on his boat flipping and sinking it. That also left them swimming out of a white shark feeding area in a panic

I love watching your videos for years, you are so fun and creative :-)

Looking forward to the next video and seeing what you come up with for the propulsion system! For the bilge pumps, big boats use float switches. Maybe there's a commercially available product but otherwise it shouldn't bee too difficult to build your own, especially with your creativity and prototyping/construction possibilities with the 3D printers. With one of those switches, only a float needs to be in contact with the water and the electronics can be kept high up. Salt water and electronics is a nightmare. Good luck!

For water level you should definitely use a ToF sensor. The Gagguino project uses one to monitor water tank height over I2C.

Fellow Seattlite here. Love watching your project adventures.

I think prop fouling could be detected if you have current feedback from your motor drives. I love watching all the engineering that goes into these boats!

I used to manage a fleet of 20 Whalers for a youth camp. We had one hull like yours. It was my favorite as the wet well could be plugged and it kept the main area dry. I had one staff take that boat out after work to go fishing and he tossed the builge pump overboard and filled the wet well with sea water to keep bait fish alive. Creative but not the best for the motor that was being washed with the overflow.

I love this channel. Please never stop uploading

You all mark my words, I will make a rc boat that will go across the UK Thanks for the inspiration

“You should snort some of that and see what happens.” is the sort of things true friends say to each other.

You cruised right past Keyport Naval Base! You should look that place up, while they mostly work on maintaining torpedo stockpiles, there is a development squadron that launched 30ft autonomous submarines that - like your boat - robotically navigate around Puget Sound! The model I used see there was the LTV-38, which was a large-displacement unmanned undersea vehicle (LDUUV)

All those slow motion shots are *chef's kiss*

For constant water level detection without corrosion you want a capacitive soil moisture sensor, they work with arduino. I think they might work pretty well even once coated with salt. I use it for my automated watering system, in the bottom of my pots I have the sensors, and when they dry out below a certain percentage it tells the arduino to send more water through.

Oregon welded fishing boats use something called a stomp great over the jet pump intake. I wonder if you could 3-D print a similar device actuated by a servo? Great video thank you for sharing

We need a music video edit of those slow motion shots! I haven't seen one of these built but a reciprocating fin like a fish tail with all rotational elements above the water line would be immune to seaweed. Its either going to have to be that, a bigger underwater prop and beefier motor, or an air prop above the water in my opinion. The fish tail system shouldn't be too hard to make a prototype for but it would probably take a lot of iteration to get it working. I love your channel!

I think for the full size autonomous electric trip next time, a catamaran is the way to go. Allows you to take tohe boat own to its pontoons and put it on a normal trailer. Water tight pontoons give you a mix of engine/battery room, and dry secure storage, netted center basically gives you a hammock/trampoline to lay in as you cruise. You could use a tent for shade and bug proof sleeping that is easily taken down during day. exterior edges give you raised areas for solar panel connection. Honestly if i didn't live in the desert I'd want to make it myself.

you could totally use a water jet if you had a large enough intake grate with a fine enough mesh, it would completely negate anything except a conveniently sized sheet getting sucked up to the intake. Im sure it would FUN to build though.

If you want a better water level sensor, you can make an RC oscillator circuit out of a comparator. For the capacitor, use a circuit board with two parallel traces routed alongside one another, but leave the traces covered in solder mask rather than exposed. The longer the traces the better. You can snake them around the board to use the full surface area, too. You'll still want to coat the circuit board (especially the edges) in a thin layer of epoxy, as FR4 will wick up the salt water, but with that design you avoid exposing the copper directly to the saltwater.

Since seaweed most probably would cause higher amp draw, an automated motor reverse function for a few seconds could be enough to clear the propellers. Some propellers are also more weed protected than others. They are seen on Minn Kota trolling motors for instance.
