The chamber offers up to 43 liters of safety floatation, with 21 liters even in the smallest boards that require only 10 PSI. Starboard pioneered Double Chamber technology in the 2013 Ocean Rescue board. Future coast guard regulations will possibly request this safety arrangement for inflatable board use in open waters.
The innovative chamber doubles the sidewalls and acts like rollable I-BEAMS. Starting just behind the standing area and continuing towards the front, the chamber is placed in the most critical area for flex and reduces deflection by 1.8 cm. The feeling of paddling with the stiff Double I-BEAM stinger is getting very similar to a hard board propelling inflatable technology one step closer to a “hard board” feel.
