The 7S Double Down aims to increase your wave count and improve your small wave game. This is the flattest surfboard in the 7S range, and it has the highest volume per size ratio. For these reasons, it’s fast, has plenty of flow, and is the perfect weapon for fatter, sub-par conditions.


OUTLINE: The nose and tail dimensions at 12” are the same, creating a larger sweet spot, and a more stable planning zone. The full nose further adds to the stability, and the ‘Corner Round’ tail allows the width to extend further back, while still achieving the smooth transitions between turns that a round tail is famous for.


ROCKER: With an emphasis on everyday conditions; flat equals flow, so the Double Down will slide into waves with ease, and maintain its speed over dead sections with minimal effort. Slight lift in the nose and tail will satisfy the more experienced rider looking for a summer groveller.


CONTOURS: Subtle yet effective, the slight concave up front creates lift when taking off, then a double concave starting in the mid zone leads into a shallow rolled vee off the tail. This bottom combination maintains exceptional speed in softer waves, yet provides a nice balance of control versus quick turning response when pivoting right off the tail.


PERFORMANCE: The Double Down is fast off the mark, and super easy to turn. Think summer beach breaks or soft point waves where you need a board with enough foam and buoyancy to get you going, but don’t want to restrict how you want to perform on a wave. We suggest riding this board will bigger side fins, and a smaller centre fin.




Innegra Matrix

Created in collaboration with Colan Australia, Innegra Matrix (IM) is an exciting new 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, we also use a high density EPS core tha’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, we still 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.
