Hi Mark,
Good list. Things most of us (should) think of but might put off. Bubbles? I think it's important to include sailing performance as part of an EP conversion.
Most of the new electric cars you see are designed with weight reducing and aerodynamic tech. Not including Neil Young's Lincoln Continental (LincVolt) :-)!
I'm starting to think the towed generator and a folding propulsion prop might be a good compromise - rather than maxing out a prop for regen/propulsion. That said I like the simplicity of using the prop that's already in the water.
Have you been getting out on your electric kayak? I enjoyed tooling around in it at the Bay Area electric boat get together.
