That boat hull, hmmm.

you have too much weight aloft and that wing sail isn't doing you any favors, a junk rig should work better for you. In your application you should only need a single line for raising the sail and a geared servo to rotate the mast, you could eliminate the line if you keep the sail up and treat it like a wing sail.

Your boat production skills are getting better and better, nowadays your boats look very decent, and smooth

It needs a wind vane at the top of the sail to track the direction of the wind, as well as a sensor to track the angle of the sail, so it can automatically set the sail at the right angle for optimal lift/drag.

This is why you shouldn’t Chose pink color for 3d designing 😂

You should make a recovery boat for when test boats fail

Jesus you scared me at the beginning, thought I was on the wrong “website” for a second

Sailor here. a couple of suggestions for making the boat go upwind better. First, use a higher aspect centerboard and lose the lead keel. You dont need the righting moment if you have amas (trimaran configuration) and the deeper draft will keep the boat from being blown sideways. Second, Id move the sail backwards a bit. the idea is you want the center of effort of the sail to be as close to the CoG as possible. With the rig as far forward as it is, you have whats called "lee helm" which is fighting the rudder servo. Ill bet you were having to hold the rudder HARD away from the wind. Dragging the rudder stalls it and of course slows you down. If the CoE and the CoG are at least close to the same spot, the boat will be a lot more balanced and will go upwind much better. You could probably get close to being able to sail at 45 deg either side of the wind.

Interesting hull shape, especially from the bottom view.

FINALLY the crossover I've been waiting for! I'm a professional rigger so if you have any questions about rig design or anything sailing related let me know!

Nobody in the comments caught what you did at the beginning. You drew me in with that 3D model.

I see what you were going for with that boat hull at :28. Nice😂

Couple of points about going upwind efficiently:

seeing 21 tango coming in was nostalgic. When I was a kid I spent probably ever other weekend at Seattle Seaplanes since my dad was flying there :,) Not sure if he's still around but the owner Jim used to do all the work that he was allowed to on the planes himself.

OnShape is the bomb!!! It's also great that Kiri:Moto is free and now I can create toolpaths for my CNC with STLs in the same place.

i really admire you man, i remember the old RCSuperPower days, i subbed when you made that rc cargo plane, and 12 years later you are still putting out bangers while having a full time job, idk how you do it but keep doing it

I race sailboats competitively in college, and I've been looking forward to this ever since you built your first autonomous boat! I can't wait to see how it goes 😊

Genuinely my favourite youtube channel right now. Seeing all the different projects that you've done on this channel makes me want to try creating things like this too
