These sizes will be similar to those you would choose in g10.
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 choppy conditions, you may also choose deeper fins to give the board more hold.
Fitting bigger fronts to your thruster or quad may make your board feel more planted and give more drive, but may also reduce the boards top end speed. It’s often better to downsize the fronts when it gets windier and you’re more powered up, as this will give less drag, more acceleration and make the sail feel less powered up and the gear more reactive to gusts giving the rider an easier time.
Reducing the size of the rears to below recommended will of course let the back release and slide out more easily, often desired for onshore conditions.
If going for a very ‘even’ thruster set up, we would recommend using symmetrical fronts rather than the Ezzy. If going for 12 fronts and 14 rear, for example, we would recommend Stubbies all round.
