The “F-5” Model: A round nose, five-fin adjustable fin setup, performance shortboard. The F-5 incorporates the latest in adjustable fin setups with one of our most proven designs. The 5-fin box design allows you to customize your fin set up according to conditions or preference. FCS fin boxes maintain the proper weight ratio and allow for extra fin boxes with out adding too much weight. The end result is board with unparalleled versatility. This board excels in small to medium size surf. It has great drive and carries speed through turns and flat spots while still turning on a dime. The addition of the bat tail channels water out the back to increase speed while still providing a pivot point for turning. Ride it as a quad for speed or a thruster for snappy turns. Have fun and experiment. Ride the F-5 2-4 inches shorter than your standard shortboard.
