ski boat for disable skiers

[waterskier]

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
