Hmmmm interesting thanks for your video :)

[@fossilfool]

Thx, we're doing another electrifcation vid in 2 days

[@Flyonwaterslow]

The best project ever 😛😛♥️

[@fossilfool]

Thanks!

You are awesome dude!!! :)

great video! thanks for leaving the melt down in it! you can in fact arc weld with a couple of car batteries and jumper leads! so that could certainly have been what you were doing there! I reckon you need a fairing on the back of the motor, like a nose cone on a propeller plane, but the nose is backwards on your boat. The basis for that prop came from a petrol outboard right? your motor is a lot wider than the outboard gearbox would have been. It might be worth considering a larger prop with fewer blades. higher aspect ratio is less drag right? I tried a 12x4 model airplane prop (diameter x pitch, in inches) on my electric outboard... and it worked a lot better than the stock one! I understand that correct prop sizing is essential to efficient operation, and RC plane props come in a wide range of sizes and pitches. (much easier to try different sizes than with an outboard prop) I'm not an expert on planing, but that didn't really look like planing to me. It should feel like "taking off" it takes more energy to get up on the plane, but once you are up you should be able to ease back the throttle and stay planing.

Thx Dominic. That prop came from Maytech and it has an unusual motor spline. I may try to increase the size and you're not the first to recommend model airplane props.

So cool! You trailed off there around 36:00. The sound is an indication of... strength?

[@fossilfool]

Thx Jeff, yeah it’s an indication of stiffness / resistance to flex. If you grab a chunk of 2x4 and hit it on the narrow side it makes a higher tone than hitting it on the wide side. The object is more resistant to flex in that vector.

Sure would be scary to lose the motor in the breaking waves :) I sail on a lake so i only use the electric motor to dock and undock. Or when the wind cuts out. Have you given your boat also a shot at stern sculling (in conditions where usual rowing would be a no-go)? Definitely get a big kill switch though. That stuff will end in tears otherwise.

[@fossilfool]

Work now resumes on the project with a focus on waterproofing the cubby and installing some kind of physical reachable kill switch. Stern sculling was terrible, unfortunately. I made a mount for the oar but couldn't get anything to happen. Regular rowing is very effective. Thx for watching!

i wonder if a toroidal prop might convert power to thrust..... 3d printer?

[@fossilfool]

Was thinking of trying to replicate the Sharrow prop in carbon. I think it would need a very strong 3D printer to handle the stresses. Thx for watching.

[@lightprint348]

@@fossilfool I wonder if a porus 3d print then impregnater with resin might work. regardless very interesting DIY space.

[@celil111]

hello, are there any plans of your boat avaliable?

[@fossilfool]

There are plans for the hull available. It's a scaled up First Mate by Ross Lillistone. duckworks.com/first-mate/ This boat was designed to be built in plywood not translucent G10. About the G10 choice and other custom mods like the outboard and the bike-towing system, my KZbin channel is the closest thing to plans.
