Default Calculating fin size

Hi

I'm trying to work out which fin(s) I should be using with my 2008 Futura 144. I'm around 92kg in weight, and on a good day, and early intermediate standard.

The board came with a 50cm fin, but when really powered up on a 6.5 Tushingham I find the nose waves around a lot - I've not had the same problem with a 7.5 or 8.5 sail, so I'm guessing I have too much lift

I looked up the fin size calculator on Boards and that suggests a 38 cm fin ... but that seems to be out of the expected fin range for the board.

I checked your tuning page - which says fin size is important but doesn't say how to calculate it ..

Could you suggest how I go about calculating the right size?

David
