Allied 42 sails: questions
How much is a new mainsail for a Allied 42?
From A$3,940.20 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$4,158 with 4 full battens. C-Breeze, the long-life cloth, starts at A$5,172.20. Every mainsail is cut to the Allied 42 rig (P 13.03 m, E 4.82 m) with two reefs.
What size genoa does a Allied 42 need?
We build 110% to 150% LP for the standard rig (I 14.67 m, J 5.03 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$3,978.70.
What size spinnaker fits a Allied 42?
A Size 8 (94 m²) asymmetric suits the Allied 42 fore-triangle. It starts at A$2,656.50, or A$3,602.50 with a dousing sock.
What size storm jib and trysail fit a Allied 42?
The Offshore Special Regulations cap a storm jib at 5% of I squared (10.8 m² here) and a trysail at 17.5% of P × E (11.0 m²). That makes our Extra Large (9.5 m²) storm jib and Large (10.8 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.
