The S215 Surf stabilizer has a lower stall to complement the SF Front Wings. Its moderate span creates an aspect ratio high enough for efficient pumping, while remaining compact for responsiveness in turns​. The minimal sweep outline improves low-speed performance and effectively reduces fuselage length compared to swept stabilizers​. Tips curve upwards to provide directional stability, inspiring confidence during takeoffs and grip in turns. ​Advanced riders seeking a looser feel may choose to remove the wingtips, using the dashed guideline graphic, to create a completely flat stabilizer with a 205cm2 area.

The Sonar High Aspect Front Wing Series is engineered for the highest speed and efficiency possible across a range of disciplines – from kite foiling to prone foil surfing. With this style of wing, you need minimal pump and power to generate glide. The shorter chord length defines the profile thickness, and with a thin profile comes reduced drag. The span gives you stability and a slightly longer radius turn than a lower aspect ratio wing of the same size. The wingtips are refined to ensure there is no ventilation when you tip breach, giving you the ability to crank tighter radius turns at higher speeds, without losing speed. With excellent lift at high speed, the HA850-HA1250 are your core wing-foiling and prone surf sizes. Downwinding: Ocean swells move faster in the open ocean – slower in shallow water or closer to the coast. The faster you move through the water, the more choice you have to choose a more efficient line. The smaller the wing, the less planing surface = less lift and higher stall speed.  The HA Series Wings are designed for lighter / more experienced riders to foil in faster-moving ocean swells.
