    Going slower for less power mostly works to stop energy use simply making waves.

    so there is a limit below which gouing slower does little.

    At SL 1 (the sq rt of the working lw )l the wave making and skin friction resistance are about equal.

    Going slower than SL 1 will reduce power required , but the gains are not very large.

    Great Job Eric!
    Its nice that somebody makes his dream real!

    Here is my fuelsave power trimaran:
    LWL: 9,9 m
    BWL: 5,8 m
    Trailerable beam: 2,55 m
    Bare weight: 1000 kg
    Berths 4+1
    Engine: 40 HP inboard diesel

    The design (still working on) is less futuristic, but provides more space in the dimensions. Two separate cabins, toilet, saloon. Trailerable without permission.
    The main hull can be used for sailing trimaran too. (One mould needed).
    Beam length ratio is 1/10.
