Seafarer 23 sails: questions

How much is a new mainsail for a Seafarer 23?

From A$1,250.70 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$1,408 with 4 full battens. C-Breeze, the long-life cloth, starts at A$1,405.80. Every mainsail is cut to the Seafarer 23 rig (P 7.01 m, E 3.35 m) with two reefs.

What size genoa does a Seafarer 23 need?

We build 110% to 150% LP for the standard rig (I 8.20 m, J 2.32 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$789.80.

What size spinnaker fits a Seafarer 23?

A Size 00 (27 m²) asymmetric suits the Seafarer 23 fore-triangle. It starts at A$896.50, or A$1,421.20 with a dousing sock.

What size storm jib and trysail fit a Seafarer 23?

The Offshore Special Regulations cap a storm jib at 5% of I squared (3.4 m² here) and a trysail at 17.5% of P × E (4.1 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.
