5'8" x 21.5 x 2.55 x 35.5L The HYDRA is a mythical, multi headed monster from the sea. It can lay waste to anything in its way. even crappy surf. From our original Pelagic, to the RNF-Retro and on to the new SWORD-FISH, every board featuring this outline has worked above expectations. It noticeably locks into the wave during carves and shortens the radius of turns while both gaining speed and maintaining control. The bottom contours feature a double concave (sitting in a single concave), with noticeable chined releases towards the rail. A design featured in our classic Bottom Feeder model. The triple concave allows the use of more curve through the rocker (which makes proper turning and vertical surfing a lot easier) by cutting through and adding lift and speed. With very wide boards, single concave bottoms easily get sticky and stay flat on the face, the chined perimeter towards the rails, add release and frees up the board from rail to rail. Making 3D rail surfing more possible, as opposed to simply skating fast on the surface, like so many traditional fish. The tail is a split diamond, which melds the characteristics of both swallow and diamond tails. The notched-out center line shortens the stringer and reduces surface area behind the rear foot, to add bite and control to a wide tail. The double diamond tail shortens the rail line making quick and radical, power retaining turns much more manageable. he HYDRA uses a flat-ish deck, with full and forgiving rails. Flat decks can remain thinner and still retain volume and are more flexible (even if thick) than vee or dome decks. Flex is good in low rocker boards, keeping them pliable and forgiving.
