Twin + 1Say hi to your new favorite twin fin design, this time + a little rear fin to surf it with any kind of shape. Many surfers coming from thruster fin setups asked us if it was possible to use Twin fin templates on their conventional performance board. This is how we started re defining our twin fin templates and adding a little fin at the back. These fins will complete your actual twin fins (the design is a bit bigger than our classic Duette template)
