For efficient hulls, look to high performance human-powered craft. For example, some of the same people behind human powered flight had a project for a human powered hydrofoil. I believe it was called the flying fish. I first read of it in Scientific American.

I've recently started looking into this again for one of my next boat builds, not least because of my realisation that it could be a nearly perfect solution to high performance, long range, long duration electric watercraft. And with pedals in the mix, getting stranded without a charge is much less of an issue. -- Ron On June 29, 2019 9:18:49 p.m. CST, Lawrence Rhodes via EV <ev@lists.evdl.org> wrote: >I am not sure if your hull was designed to plane but if you force 10 >mph you are wasting energy.
