I will reply to this a second time, sorry if you receive this twice.
I don't want to be rude, but what you are asking is like, is my 5.2 require a 430 or a 400cm mast. Well depend of the shape, brand etc. So, yes, you are right in the range of if but better look with the fin company you want to purchase.
If you take a look at my friend's company proposition, for that specs, you are looking for a 38cm hahalua fin, so yes 38cm seems in the range. However, with other compagny, maybe longer? cheers mate.

I'm after a weed fin but don't know what size to get. I'm 96kg (today), to be used on a 259cm x 70cm x 135L board and main sail is a 7.5 for up to 20knots on mainly flat water. Guessing 38cm or 36cm? Suggestions?
If you've got one for sale to suit a Power Box please give me an hoy. Thanks.
(Edit: I use a 42 Caveman Freeride on this board which works very well if that helps in what size I may need.)
