San Juan 30 (tall mast) sails: questions

How much is a new mainsail for a San Juan 30 (tall mast)?

From A$1,677.50 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$1,816.10 with 4 full battens. C-Breeze, the long-life cloth, starts at A$2,252.80. Every mainsail is cut to the San Juan 30 (tall mast) rig (P 10.67 m, E 2.90 m) with two reefs.

What size genoa does a San Juan 30 (tall mast) need?

We build 110% to 150% LP for the standard rig (I 12.04 m, J 3.81 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$2,024.

What size spinnaker fits a San Juan 30 (tall mast)?

A Size 4 (57 m²) asymmetric suits the San Juan 30 (tall mast) 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 San Juan 30 (tall mast)?

The Offshore Special Regulations cap a storm jib at 5% of I squared (7.3 m² here) and a trysail at 17.5% of P × E (5.4 m²). That makes our Medium (5.7 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.
