    If Delftship states a resistance force of 700lbs at 10 knots, can that be converted to Hp?

    Is Delftship resistance calculation accurate for a long thin hull?

    Power can be calculated. It will be the rate of work done, not the engine power rating needed.

    Power = Force x Speed x Units conversion factor

    Maybe. Kaper might be, but only if your hull is about the same length and shape as a kayak.
