Sail size / board size / fin size

Got asked yesterday what equipment setups do I use. It differs from training, competition training and competition.

I use Patrik Diethelm boards, Neil Pryde Evo 7 sails and Black Project Fins

Competition

Board                            Sails                              Fins
PD 135                     9.5 & 8.6                           R45
PD 110                       8.6, 7.8, 7.0                      R35
PD SPEED 52         7.8, 7.0, 6.4, 5.8           RS28,  RS26, S29 & S26.5

PD SPEED 41              5.8, 5.4                           X55

Training

PD 135                      9.5 & 8.6                 R45 & R47.5
PD 110                        8.6, 7.8, 7.0                   R37 & R35
PD FSW 102                   6.4                                 RS30
PD SPEED 52          7.8, 7.0, 6.4, 5.8            RS28,  RS26, S29 & S26.5
PD SPEED 43              6.4, 5.8, 5.4                   X40, X45

I try and get away with the smallest fin I can. Instead of changing fin as the wind picks up I would probably change board and fin. Once I have found the right fin for the board it rarely changes with the exception of the PD 52 which has the most options with fin type.

The sails cross over a lot and I have always options.
