Thanks for the info. This is very useful. If 32 works for your 6.2, my 31 fin should be OK for 6.0. I will do some testing to see if I can get it working, otherwise I'll try another brand. Also good to know that 38 is also working for the s-type 104. I've heard today in the shop that this should be big enough to handle a 7,5 (rule of thumb is multiplying the sail size by five, so 7,5 x 5 = 37,5 cm.
