Cal 25 sails: questions
How much is a new mainsail for a Cal 25?
From A$1,339.80 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$1,496 with 4 full battens. C-Breeze, the long-life cloth, starts at A$1,507. Every mainsail is cut to the Cal 25 rig (P 7.62 m, E 3.35 m) with two reefs.
What size genoa does a Cal 25 need?
We build 110% to 150% LP for the standard rig (I 9.11 m, J 3.05 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$1,156.10.
What size spinnaker fits a Cal 25?
A Size 1 (37 m²) asymmetric suits the Cal 25 fore-triangle. It starts at A$1,214.40, or A$1,774.30 with a dousing sock.
What size storm jib and trysail fit a Cal 25?
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 (4.5 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.
