Looking to go faster as always. A bit of forward thinking. Im 105kg. Intermediate skills. Ive got an old board lying around SPEED World Cup Slalom 270 x 54wide. Looks about 105 - 110 litre. Mastrack measures 135cm from tail.

Flat into V underside.Rails are more like chines, square n sharp. Would this ol thing be suitable as a speed board for my 105kg? Im guessing 6.5-7.5m sails. Pointer fins around 30- 40cm.
Whatcha reckon?
