    I am looking for assistance in designing a ski boat for disable (wheelchair) slalom waterskiers.

    The problem
    Current centre mount ski boat whilst have a small wake at able body ski speeds it is too big for wheelchair skiers.

    The idea
    Could a light weight v nose aluminum punt with centre mount ski boat be the answer.

    The fixed paramaters
    For competition the following is required.
    Centre mount motor
    Centre mount ski pole
    Boat length 6-6.5m
    Must be able to track straight whilst withstanding lateral load of skier.
    Min skiing speed 39k(22mph), max skiing speed 58k(36mph)

    Thank you

    I would find a hull that flattens at the rear and consider putting a full lengh trim tab across the transom to flatten the prop wave. Something that sticks out about 6" and can be adjusted upward when not pulling a skier.
