Hi Pfaffi,

you fins look interesting (and good!).

What's the reason for the tip shape?

Cheers
Cholo

Hi Cholo!

Fins are designed to maximize lift by a minimum of drag. Out of this is the special Tip shape. Additional to reduce the twist by outline design and not only by twist reinforcement. The used laminar profile is one of the fastest and non critical. Find some lift/drag diagram and profile views on my starting page.

Tested 117 w from 18 kts to 30 kts.I found out the following set ups were excellent:

18-23 kts. low chop 0.2 m -severne code red 8.3-deboichet silver select 44 cm deep tuttle
25-30 kts.moderate chop 0.5m-severne code red 7.0-maui techtonics 40 cm tuttle

I am 84 kg.Surprisingly the board did not feel big or heavy or uncontrollable at 30 kts.On the contrary it felt even better than IS 101.Strange...
