US 33-1 sails: questions
How much is a new mainsail for a US 33-1?
From A$2,137.30 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$2,285.80 with 4 full battens. C-Breeze, the long-life cloth, starts at A$2,816. Every mainsail is cut to the US 33-1 rig (P 11.67 m, E 3.14 m) with two reefs.
What size genoa does a US 33-1 need?
We build 110% to 150% LP for the standard rig (I 13.11 m, J 4.21 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$2,612.50.
What size spinnaker fits a US 33-1?
A Size 5 (64 m²) asymmetric suits the US 33-1 fore-triangle. It starts at A$2,069.10, or A$2,839.10 with a dousing sock.
What size storm jib and trysail fit a US 33-1?
The Offshore Special Regulations cap a storm jib at 5% of I squared (8.6 m² here) and a trysail at 17.5% of P × E (6.4 m²). That makes our Large (7.5 m²) storm jib and Small (6.1 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.
