Don't...there's no replacement for displacement.

Sorry...I probably shouldn't have.

Skip it for now--in our industrial setting it involves charging every break and lunch and topping off overnight.
For this to work it needs a breakthrough in battery technology--or staying within rowing distace of the dock-YMMV.

Try to keep it small scale and you won't have to spend million$ and years, before getting ready to splash it.

Wow, those are awesome!! Any details you can share? I recently just bought a Pro Boat Sonicwake 36 and a Pro Boat 36" Miss Geico boat.

Boats take a lot of energy to move through the water. Unless you are going very short distances, battery power is not practical. Would need more information to give any guidance.

This one has been on my projects list for a while also. The Electric Cig never even floated to best of my knowledge. Waste of a perfectly good hull IMO.

A lot of this topic depends on range expected, at what speeds. Couple year back I started speaking with an EV racer about possible options. His specialty is going zero to 180mph in less than a quarter mile. As where the Buckeye Bullet team focuses on reaching a 340mph top speed over a much longer distance. One setup uses a bunch of stacked batteries [weight] and fairly common 400bhp [motor] to slowly wind up to speed. The other design uses a 1000bhp / 2000lbft stepper motor, wired up to a very small fast discharge rate battery pack that's fully drained in under eight seconds.

So if you wish to build a 140mph single "motor' electric shootout boat, hit me up I have hardware lined up to borrow for a proof of concept run. Or it should cost around a 100k to purchase all the components to rig a 30' boat. If ya wish to do a performance hull to cover a 100 mile range at over 50mph, probably gonna need to add a couple more of those fat stacks just in batteries... My goal of covering 35 miles or so at equivalent of combustion engines, in say off shore racing environment, is not quite ready for prime time...

My thought would be a very light cat hull,,, or hydro foils. A Swedish friend showed me one let me see if I can find it.

EDIT: Found it. not very fast 50 mile range.

Where did the electric 38 Cigarette end up?
