The new American designed C-zero-5 is a true all-purpose cross-cut sail developed through extensive on the water testing with Christopher and Duncan Williford. Garth Reynolds and Brian Bissell teamed up with Christopher and Duncan using the N2BTS (North Two-Boat Test System) with the goal of designing all-purpose mainsails that will be competitive throughout the entire windrange. The C-zero-5 and D-zero-6 have fine tuned shaping throughout, allowing the sailor to find separate “fast-forward” and “point” modes at will. This sail will suit sailors over 43 kilos. The sail comes with battens, window, IODA button, tell tails and sail bag.
