In response to the question about semi-displacement hulls you may be interested in the following report on the Wye Island Electric Boat Marathon. They vary from displacement to planing. See https://www.proptalk.com/2017-wye-island-challenge-electric-boat-marathon/

But I might be wrong there, no experience.But what about a semi-displacement hull? Anyone with experience with that? Do you go thru a big power range to get onto a plane then taper off, but still rather high power to stay on plane?
