Lost Surfboards by Matt 'Mayhem' Biolos, Official Online Store Australia.The RNF Retro is our latest spin on the always evolving Round Nose Fish. Lost RNF. First off, the tail is wide for that effortless glide and retro vibe. The board prominently features a snow- board-esque, double side cut outline. Like with a snowboard, the sidecut 'grips' the riding surface and allows for more radical, tighter radius direction changes on wider, otherwise difficult to turn sharply, outlines and flat rockers. The sidecut hooks into the wave face and turns surprisingly sharp, without the usual drift or skip or slip, associated with common wide tail fish shapes. The flat deck allows the board to be ridden thinner, which enables more flex. Thin flat decks maintain more scoop in the deck rocker, which when surfed with the rail buried perpendicular into the surface, helps low rocker boards turn in tighter arcs, rather than tracking or flatten-ing out. All these elements are built around our time tested and proven RNF rocker bottom curves. The RNF Retro is flat up front with the slightest of single concave through the center, and a spiral vee from the fins back. This equates to a fast, yet precise and comfortable, familiar ride, without sacrificing glide. Keels are fast and fun, but spilt keels perform better. The RNF Retro is designed to be ridden with split keels, or a Twin + two (small trailers) quad setup. There is no rear fin box on this board. The RNF Retro is Groovy Smooth Glide Vibe - meets proven Mayhem ProFormance. Now you can have your cool and rip it too. *Please note that the price shown is for a white board with no spray. Fin options are FCS unless otherwise shown.
