Recently bought a 121L Fanatic Slalom Board and i am at a loss as to what size fin i should be using for it.
I'm normally on a 80L slalom board with a 27cm Speed Weed in shallow water going for speeds.
The board came with a 51cm slalom fin but it feels really draggy and anything smaller spins out really easily. Im looking at sailing in Port Phillip Bay so water depth won't be an issue like it normally is for me.

Board is a tuttle box.
I'm looking at sailing on a 6.0m or 6.7m (maybe getting something in the 7.0-7.5m range later) in 12-20 knots of wind. Control across chop/swell and getting upwind is important.
Board is 75cm wide, 232cm long and 121L
I weigh 75kg


What size/type of fin would work with this board?

Cheers, Moose.

I'd be looking for a 32-40cm.

Try asking some of the other locals - they may have something you can try out... then you will know what feels comfortable.

Hi that fin is actually a 51 cut down to 49, I was using it in light wind with the 8.5. For stronger winds and 7.5 sail I used a talon 46, which also is a bit too big. With your sails I would use something around 40-42. The Falcon spins out easily in chop, keep the mast track middle or a bit more forward
