Bic 46cm Trim Box Fin
This is the stock fin that came with the first generation of Bic Techno 293 windsurfing boards, that had a trim box fin box. The newer models of Techno 293 have a deep tuttle fin box (which has the fin held in with 2 screws through the top of the board). This also makes a good medium to large size fin for any of the older Bic Techno boards that have a trim box. Made by Select fins, this fin has a slightly swept back tip to keep the board controllable in chop and easy to jibe.
