Cooper 56 sails: questions
How much is a new mainsail for a Cooper 56?
From A$6,647.30 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$6,905.80 with 4 full battens. C-Breeze, the long-life cloth, starts at A$8,658.10. Every mainsail is cut to the Cooper 56 rig (P 16.46 m, E 5.79 m) with two reefs.
What size genoa does a Cooper 56 need?
We build 110% to 150% LP for the standard rig (I 18.90 m, J 7.01 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$8,716.40.
What size spinnaker fits a Cooper 56?
A Size 13 (165 m²) asymmetric suits the Cooper 56 fore-triangle. It starts at A$4,704.70, or A$5,990.60 with a dousing sock.
What size storm jib and trysail fit a Cooper 56?
The Offshore Special Regulations cap a storm jib at 5% of I squared (17.9 m² here) and a trysail at 17.5% of P × E (16.7 m²). That makes our Maxi (12 m²) storm jib and Maxi (15.5 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.
