Twin Fin Guide

‘Twin fin’ templates features a large surface area and upright design, allowing for tight turns in the pocket. Some twin fin sets include a mini stabilizer fin which draws the turn out slightly.

‘Keels fins’ offer stability, classic glide and trim for high speed ‘down the line’ surfing.

If you board shaper recommends a specific fin for your board we would always advise you to stay with this recommendation.

There are no surfer weight/size guides for twin fins and keels as they are generally suitable for all weights and sizes of surfers. Note: You may find some fins identified on catalogues/stock numbers as ‘Large’ or ‘XL’, but this is just used as a comparison to thruster fins and is NOT a weight guide for users.
