surfboard fins

[silly_steph22]

Hello. I am currently undertaking a school project on surfboard fins. I am aiming to design a new fin, with a developed fitting to the surfboard.
For part of my market research, I am interested to know if anyone has any ideas about the design of a new fin.
I am looking at strengths and weaknesses of existing products too, so if you have any of these regarding the type of fin you use, or would like to use, I would be grateful for this information too.
I hope to specifically analyse 4 main fins. The 9.5" Turbo Tunnel. The 9" O'fishl Proteck short board Centre Fin, The rubber flex fins, and the super flex fins. So if anyone has used these fins, please could you let me know about how they are in general?
Thank you very much for your time
Steph

id look in to the way a fin is fixed to the board more than concentrating on actual fin design...try lookin through the archives at www.swaylocks.com (dont ask daft questions over there they dont like it ) good luck !
