From A$2,942.50 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$3,137.20 with 4 full battens. C-Breeze, the long-life cloth, starts at A$3,943.50. Every mainsail is cut to the Nautic 311 rig (P 12.70 m, E 4.25 m) with two reefs.
We build 110% to 150% LP for the standard rig (I 12.40 m, J 3.47 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$2,036.10.
A Size 3 (50 m²) asymmetric suits the Nautic 311 fore-triangle. It starts at A$1,628, or A$2,293.50 with a dousing sock.
The Offshore Special Regulations cap a storm jib at 5% of I squared (7.7 m² here) and a trysail at 17.5% of P × E (9.5 m²). That makes our Large (7.5 m²) storm jib and Medium (7.8 m²) trysail the right sizes.
Measure I, J, P and E and compare them with the rig table. We confirm every measurement with you before the sail is cut.
