Looking at trying to maximise my TOW on Moreton Bay.

So what would plane earlier under my 75kg?
- an IMCO style race board
- a formula board
- a SUP with mast track

Which one would work best with a 7.5 freeride sail?

Would the long race board make a better board for general bashing around the bay in lighter breezes than the formula? (my impression is that it would)

How much better would these be than my current 115 litre freeride (Exo Scross) at getting planing sooner? (I think I can get going in about 13 kts with the 7.5 maybe slightly less)

Would my 7.5 freeride sail pull my arms out at sub-planing speeds on a long board?
