The RHM-4 Mainsail is designed to compliment the stiffer masts in the fleet with a well balanced combination of broad seam shaping and luff curve to suit the stiffer masts. This sail has proven itself to be very quick throughout the wind ranges. The Bi-Radial construction is manufactured using Contender RSQ 6.05 and Contender PK 5.52.
