This fin looks fast but will I ever get enough wind to use it?
I guess I will also need a board to use it with!
just looks like a copy of a techtonics goldwing. nothing new there. More of a slalom fin to me
Maybe that it is 10 years ago.I used this outline and worked a cut out at the base
and doubleconcave (diagonal.)Later found I that elliptic outline is faster. They were made all with rake 17°. 3-4 years ago the first rake 30° speedfin.I worked
the fin wider and she made 50 knots topspeed with Thomas Döblin. 22cm.
100% carbon. Now I work some fins only at the base wider,they start earlier to plane,good for GPS. Its a wide base fin. Please look: www.designlessacher.eu

Hi Legless. Come to speed fortnight. You won't get a better chance to use it! 
That looks like a very nice Alpha fin to me for a 30 knots Sandy Point Easterly. I volunteer to try it for you.
