I have a fanatic FSW stubby on order. A 105l. It comes as a thruster with a 20cm centre fin. They say it can be ridden as a single fin.

the fanatic blast 100l has a 34 cm fin. This is fanatic's free ride or "free carve" board.

i am interested to know, if I put a 34cm free ride fin in a FSW will it behave like a free ride board?

why? I hear you ask. Sometimes I want to put my 6.5m sail up and get planning in light winds. The focus being to blast around. I am fully prepared to sacrifice manoeuvrability.
