Hunter 31 sails: questions
How much is a new mainsail for a Hunter 31?
From A$2,146.10 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$2,303.40 with 4 full battens. C-Breeze, the long-life cloth, starts at A$2,846.80. Every mainsail is cut to the Hunter 31 rig (P 11.28 m, E 3.35 m) with two reefs.
What size genoa does a Hunter 31 need?
We build 110% to 150% LP for the standard rig (I 13.32 m, J 3.66 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$2,308.90.
What size spinnaker fits a Hunter 31?
A Size 4 (57 m²) asymmetric suits the Hunter 31 fore-triangle. It starts at A$1,849.10, or A$2,549.80 with a dousing sock.
What size storm jib and trysail fit a Hunter 31?
The Offshore Special Regulations cap a storm jib at 5% of I squared (8.9 m² here) and a trysail at 17.5% of P × E (6.6 m²). That makes our Large (7.5 m²) storm jib and Small (6.1 m²) trysail the right sizes.
How do I check my boat matches these measurements?
Measure I, J, P and E and compare them with the rig table. We confirm every measurement with you before the sail is cut.
