Well i took these 3 fins.

And made thses out of them.



The little twin fins are for my tabou twister 100, they are about 132mm tall.
The powerbox fin is now 16cm.
I chose elliptical tips this time to see if they are less dragy.
Now i just need to go and test them.

Bit the bullet and did this at Sandy Point today, and the results were awesome...

Got some strange looks doing it though.

1) Take the 24cm "Freestyle" fin that came with the board

2) Take a saw (preferably a big one, for effect), and cut it in a straight line so that it is now approx 16cm

3) Take some wetndry sand paper to it for 30 seconds to take off some of the rough edges

4) Put fin in board, go sailing.

Result? Perfection.
