Width

The wider your rear wing, the more roll stability your setup will exhibit. Winglets or anhedral/dihedral shapes will aid in directional stability, fighting yaw. But those variations will affect the roll stability less than downright width.

Chord

The more chord your rear wing features (leading edge to trailing edge), the more pitch stability you will have. Interestingly, fewer wingspan and narrower chords will create a more responsive foiling setup. make for a faster reaction in their roll and pitch directions.

RIBLET REAR WING TRIM SHIM KIT

These rear wings require the Riblet Shim Kit, which come in a pack of four, ranging from 0-3 degrees, with 0° being the fastest shim in the setup, perfect for high-speed downwind runs.

The 1° shim gives the least amount of drag, increasing speed but requiring some pumping to get up on foil.

The 2° shim offers a great balance between stability and speed. It is the best choice to start out on.

The 3° shim gives the most lift and is the easiest to get up on foil.

Essentially, the tuning of your foil setup is a tradeoff between convenient lift and inconvenient drag. Choose your shim depending on the conditions and swell for the best possible foiling experience.
