RE: windsurfing e.t.c
As well, if you need bit bigger sails the sort depends on what discipline you do. But go Severne. The Sizes you would probably need that are bigger than 3.6 is a 4.0m and if you want a 4.5. I'm 60kg and normally the biggest sail i use is 4.5 but sometimes sneak out on a 5.0m when it's really light. Smallest is 3.0m.
