Starboard 2019 iSonic Speed Slalom

MAXIMUM EFFICIENCY  

In general, the updated iSonic shapes have more control. With more control, we could boost the volume to improve bottom-end performances: getting planing, accelerating out of jibes and keeping speed through lulls. Choose your new iSonic sizes carefully:

63 (replaces the 2018 iSonic 90), 
67 (replaces the 2018 iSonic 97):
more compact by reducing length 3cm, their new rockers match the reduce lenght, adding control when racing downwind in heavy seas. We also modified the front foot rails to be boxier, delivering more power. The increased volume improves performance in the lulls.

72 (replaces 2018 iSonic 107):
more compact by reducing length 3cm. There is a new rocker to match the reduced length, adding control when gunning downwind in heavy seas. We also modified the rails from back to front foot to be boxier, delivering more power. The increased volume improves performance in the lulls and new cut-aways reduce wetted-surface, further increasing top speed. Ready to foil.

77 & 83: 
unchanged shape compared to the 117 & 127 except for the removal of the jibing hump on the deck. This iSonic carries the same shape concept as the next two larger sizes, bringing with it more lightwind emphasis. It is the choice for lighter racers in light winds and the powerful option for medium to heavy weights in medium winds. Ready to foil.

85 (replaces the 2018 iSonic 137):
the board with the most performance improvement year on year. A step forward so significant that it has our PWA Slalom team frothing for the new season. A new rounder outline improves jibes, making the board 2cm narrower at 20cm. The back inserts are 2 cm further back  and new, larger cut-aways reduce the wet surface further. You get a board with more lift, a board that really flies over the water tracking on just the fin. Feel the gain in acceleration and top speed. 

91: 
unchanged shape compared to the 147. Ready to foil.
