Re: [Electric Boats] New member, developing electric outboard

Absolutely would love to see it on a cruising power cat even. My dream is a solar power cat and the only way I see it having enough solar space is in a power catamaran.

My company just finished the engineering prototype of our 20 kW (continuous) outboard motor. This isn't a conversion; it's a new development, with no seawater loop, and a very small upper unit (far smaller than any gas outboard). It runs at 1500 RPM with a large custom prop, so its efficiency is high, and it provides the propulsion of a 35 HP gas outboard.

The battery packs weigh just under 100 lbs and contain 6 kWh each of li-ion batteries. These packs can be combined (working in parallel) to reach higher battery capacity for longer range.

One question I have for this group is: what hull do you think would best show the capabilities of this system, and the benefit of clean, quiet power? We're currently using a hull that rowing coaches normally use, but that's not mainstream.

Thanks.
