I can use the sail from about 13-14 knots all the way to about 19-20 knots confortably. Maybe with a smaller 40cm or 38 cm I can use it to about 22-23 knots.
I use it like that to make sure I have power after a crowded jibe in the bouys. Planes really quick and has pleanty of top end for real racing.
If I have to go to 7.0m2 I will use my iSonic 101 instead with a 36-38cm fin for 18knots all the way to 25 knots.
The sails I use are TR-6 from MauiSails. Canefire Fins from Vector Fins Carbon Molded and F4 Fins the D2.
