Believed to be 7S's best Super Fish yet, the Super Fish 4 IM Surfboard is an amalgamation of the Superfish 3 shape, with some old design features from the past, yet still offers the perfect balance of stability and turning response. Created with an exciting new material, IM (Innegra Matrix), this board's construction helps to control the torsional flex with woven fiberglass, while the carbon strands control the longitudinal flex, resulting in a poppy and lively feel from the EPS core, but with the underlying feeling of control and dampening that's closer to a traditional PU board. Less chatter and more dampening means a smoother feel through turns. Parallel rails and extra width through the nose creates a really stable platform and helps you generate speed. A tapered tail outline maintains nimble maneuverability, and the flyer creates a release point when turnings. The swallow tail adds bite on the face of the wave, especially when glassy conditions prevail. Single-to-double concave creates tons of speed down the line, and provides sensitivity off the tail when transitioning from rail to rail. The balanced rocker has just enough lift in the nose to prevent nose dives on steeper waves, and moderate curve off the tail keeps the board responsive when driving off your back foot. Plenty of volume in the chest provides paddle power so you can get into waves early, and full rails keep the board sitting high in the water.
