My question is, what is the most efficient hull
shape for low speed use. Around 5 knots.
I am aiming for a sub 6m length. As little draught as possible.
For use on very protected waters only. No wave handling is really needed.
Total weight around 1000KG. Ideally a multi-hull for wide tramp decks.
The idea is to use electric propulsion
and a crab claw
sail for downwind work. Plus a backup outboard
shared with the dinghy!
I have done a lot of reading into hull
efficiencies with different shapes but not a lot seems to deal with low speeds.
So, does anyone know what hull shape is most efficient at low speeds? I know any skinny long hull is pretty good, but there seems to be a lot of opinion on entry and exit shapes etc.
