San Juan 23-2 sails: questions

How much is a new mainsail for a San Juan 23-2?

From A$1,232 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$1,369.50 with 4 full battens. C-Breeze, the long-life cloth, starts at A$1,382.70. Every mainsail is cut to the San Juan 23-2 rig (P 7.93 m, E 2.90 m) with two reefs.

What size genoa does a San Juan 23-2 need?

We build 110% to 150% LP for the standard rig (I 9.14 m, J 2.90 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$1,102.20.

What size spinnaker fits a San Juan 23-2?

A Size 0 (31 m²) asymmetric suits the San Juan 23-2 fore-triangle. It starts at A$1,020.80, or A$1,545.50 with a dousing sock.

What size storm jib and trysail fit a San Juan 23-2?

The Offshore Special Regulations cap a storm jib at 5% of I squared (4.2 m² here) and a trysail at 17.5% of P × E (4.0 m²). That makes our Extra Small (3 m²) storm jib the right size. No stock trysail is small enough for this rig, so we quote one to fit.

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.
