The world's all-time best selling fish model surfboard. During the filming of 5'5" REDUX, the RNF and RNF Quad were updated and fine tuned. The nose has gotten wider again, and more conservative overall rocker and less concave make for a board that will hold speed in flats and produce harder, longer carves.

A longer, less pronounced vee in the tail gives a more predictable feel out of turns, and a straighter outline adds drive and hold. The deep wing, influenced by MR's vintage twin fins, adds more control of high speeds and better bite in snaps and out of carves. It still paddles great, still makes you look good, but the updates allow harder, more powerful carving turns and a wider range of performance in more varied surf.

Enjoy playing with a multitude of fin setups. The RNF is designed as a twin with rear trailer, but works great as a pure twin fin or try all three standard thrusters for different feels in different conditions. ...Everyone should own one.

Lost Round Nose Fish Surfboard Details:

• 5'6 x 19.5" x 2.32"


• FCS Fins


• Wave Height 1-6'


• Made from Hyrdroflex Technology

Hydroflex Technology: With Hydroflex Supercharger technology, the flex of the surfboard can be adjusted by increasing or decreasing the amount of compressed air in the surfboard. The surfboard comes complete with an adapter and pump that connects to the surfboards internal valve. By connecting the pump to the surfboard you can add more air making the surfboard ride stiffer and have less flex. With the press on the needle valve with your finger you can release air making the board softer and have more flex. This allows the surfer to adjust the boards stiffness based on surf conditions for optimal performance. Hydroflex surfboards are made from stringerless eps blanks and epoxy resin, but with a patented 3 dimensional glassing. The glassing anchors the fiberglass and epoxy resin into the foam core creating a root like structure. This creates increased stength and prevents delaminating.
