They do look "big" in the photo Gary, (not so big in the "flesh" I think). No noticable drag in any wind strength though and they certainly stop the noses from "dipping" when the wind is up.
I will post a report shortly on the weekend at the Sauna sail, BUT GOD IT WAS COLD THERE, (then again from all reports that weekend was bitterly cold across most of the southern part of the continent). That is one "unique" place to sail at Garry, unlike anywhere else that we have ever competed at.
Ohh. you know that now that you have taken photo's of the "T" foils I am going to have to kill you!
We have made these foils so that, using the same mold we can make the foils as an "L" foil by leaving off the outside blade of the T. Thats so that any cat that is at it's maximum beam width can still use them and measure to their overall beam. That isn't a problem for us as the Alpha is narrower than the maximum allowable beam of the formula
