The exemplary embodiments herein provide a bridle for use with a rigid wing having two opposing ends, the bridle having a fixed bridle member attached to a bottom surface of the wing, a pair of connection points positioned on the fixed bridle and located at distance D vertically below the bottom surface of the wing, a rolling bridle member with a pair of opposing ends, where each opposing end is attached at one of the connection points, and a pulley with a sheave that travels along the rolling bridle member. In some embodiments, a motor is mechanically connected with the sheave. In some embodiments, the distance D is optimized for a preferred roll moment as the wing rolls through various angles.
