Twin Fin

Twin fins have always been a staple option in many surfer's quivers but have enjoyed a resurgence of late with the renewed interest in retro board designs. Twin fins either come as a twin set with just the two side fins or as a 2+1 set which includes the side fins plus a smaller stabilizer fin as well. 

True twin fins are very fast and have a lot of pivot but can feel 'loose' for some riders. A 2+1 configuration will give twin sets a bit more hold so that you aren't sliding out when engaging your rail.
