Fin sizes at a glance for a 75Kg (165lb / 12stone) wavesailor on an 85ltr board, then a 75ltr board for below 5.0

These sizes will actually be similar to the sizes you would use in g10 but feel looser, lighter, grippier, more controlled with more drive and hold through the turns, at the expense of some low end early planing power. You'll also notice the flex will sling-shot you out of your turns and provide grip at extreme angles where stiffer fins would leave you bum checking as the tail slips away.

Please note that wider boards and/or heavier/taller and/or less skilled riders will require longer fins than those shown in the table and vice versa.

In really windy choppy weather, you may also choice bigger fins to make the board more 'planted'
