Surprise yourself with quick improvement on the versatile 7S Superfish 4 IM Surfboard. The Superfish 4, or SF4, is an amalgamation of the Superfish 3 shape, with some old design features from the past. While still targeted at surfer’s looking for a high volume modern fish shape, some believe this is the best Superfish yet; offering the perfect balance of stability and turning response. A wider nose, a fuller outline up front, and parallel rails create a large stable platform through the middle to generate speed. With added volume under the chest and extending towards the nose and tail, the SF4 provides amazing paddle power so you can get into waves early.

The 3 stage rocker is well balanced, with just enough flip in the entry to prevent nose-diving in steeper waves. The flatter midsection maintains forward drive and flow and moderate curve out the tail presents the opportunity to really jam a nice turn when pushing harder off your back foot. By eliminating the flyer and making a smoother curve in the back half of the board, the tail outline tapers so you can make tighter radius turns when you position your back foot right on the tail. The swallowtail adds bite in smoother conditions and paired with the return of the original step deck you gain increased volume through the spine and out towards the rails, creating a flatter deck while allowing for a lower, more sensitive feeling rail. A single-to-double concave delivers a very consistent and predictable feel, without restricting speed or the ability to transition quickly from rail-to-rail between turns.

Renowned for its wave catching prowess, the Superfish 4 really does appeal to a wide demographic. It’s the perfect board if you’ve just started turning and you want to progress to the next level of performance. Or maybe you’re getting a little older, you’re struggling on a smaller board, and you want to keep turning. From knee high, to well overhead, the SF4 will keep you coming back for more.

Created in collaboration with Colan Australia, Innegra Matrix (IM) is an exciting material that’s exclusive to GSI and the 7S board range. IM consists of 3oz bi-axial fiberglass orientated at +/- 45 degrees, an Innegra cross-net woven through the fiberglass, plus 13 unidirectional carbon strands, all of which forms a single layer of fabric that's laminated on the bottom of the board. The deck lay-up has a quad-axial configuration of fiberglass at +/- 45 degrees & standard 4oz fiberglass at 0/90 degrees. With this build, GSI also uses a high-density EPS core that's cut and finish shaped, and a special ultra bright epoxy resin. Overall this construction helps to control the boards torsional flex (twisting), while the carbon strands control the longitudinal flex. As a result, they achieve that ‘pop’ and ‘lively’ feel from the EPS core, but with an underlying feeling of control and dampening that’s closer to a traditional PU board. Less chatter, more dampening = smoother through turns.
