fin placement

I’m shaping a 5’10" Steve Lis style twin fin but am unsure about the placement, toe-in and angle of the keel fins. If anyone has shaped a similar board I would greatly appreciate some advice. Also, are the any books/websites about hydro dynamics that relate to surfboards and fins?? Thanks, Randall

Howzit Randall, I can call Steve and ask him for the fin placement if you want to know from the Master himself. Just talked with him and Betsy last week, he wants me to glass some boards for him.Aloha, Kokua

Randall,I don’t think Steve uses keel fins. Aloha,Kokua
