The modern all-around logging fin. The Redline takes everything we have learned from high-performance mid length surfing and blown up to work with boards over nine feet. The concave taper adds twang and creates efficient tip wash-out. This fin is our choice for most modern longboards, from high-planing performance to heavier rolled bottom logs. Smooth, reactive, efficient. If you're going to get shipwrecked on an island with one fin this is the one.
