A twin fin plus small centre fin combination that will work great in any twin or twin+1 board, not just the Lost Evil Twin. The fin template is an exact replica of the twin fins designed for the original RNF 25 years ago, featuring an upright profile, with a swept back tip, and plenty of area. The smaller than average trailer helps draw out turns and offers more stability and projection. However, the fin Evil Twin retains that free feeling, twin fin feel even in solid powerful surf.
