The RHC mainsail is our latest design and continues to win more major regattas, since its introduction than any other sail over that time period. Sailors using the RHC main have won multiple North American championships and Midwinters. The RHC was developed using the AP mainsail shape, to be a superior sail in all wind conditions while improving speed and adding durability with radial construction in the high load areas. The radial head and clew sections make the sail smoother while keeping the same easy-to-tim shape of the AP. The RHC also has a bit more depth in the forward mid-section to allow easier gear changing in breezier conditions.
