From A$3,025 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$3,241.70 with 4 full battens. C-Breeze, the long-life cloth, starts at A$3,874.20. Every mainsail is cut to the Lapworth 39 rig (P 10.58 m, E 4.79 m) with two reefs.
We build 110% to 150% LP for the standard rig (I 12.35 m, J 4.57 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$2,858.90.
A Size 6 (75 m²) asymmetric suits the Lapworth 39 fore-triangle. It starts at A$2,125.20, or A$2,964.50 with a dousing sock.
The Offshore Special Regulations cap a storm jib at 5% of I squared (7.6 m² here) and a trysail at 17.5% of P × E (8.9 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.
