RE: Drake fins, cheap but not chearful
Geo, you got me right, I did mean the Curtis designs when I wrote "Drakes"; sorry for the confusion.
Like you, I have difficulties finding out a reason why SB continue to supply the iSonics with that Deboichet Design fin, when they have a better design. Perhaps it has to do with the fact that both Tiesda and the late Per are lightweight sailors, who do not load the fin very much, and they cannot test the limitations of that fin?
In any case, I have a sailing buddy who is a better sailor than me, and he can make about any piece of windsurfing equipment work (he loves using discarded or old gear, and make it work well); he even uses a 34 cm square fin from the HyperSonic 105! Yet, he has tried, but will not use the Deboichet Design supplied with his Sonic 95 any longer.
