Garrett 40 (masthead rig) sails: questions

How much is a new mainsail for a Garrett 40 (masthead rig)?

From A$3,799.40 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$4,011.70 with 4 full battens. C-Breeze, the long-life cloth, starts at A$4,888.40. Every mainsail is cut to the Garrett 40 (masthead rig) rig (P 13.84 m, E 4.69 m) with two reefs.

What size genoa does a Garrett 40 (masthead rig) need?

We build 110% to 150% LP for the standard rig (I 15.79 m, J 4.57 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$3,656.40.

What size spinnaker fits a Garrett 40 (masthead rig)?

A Size 8 (94 m²) asymmetric suits the Garrett 40 (masthead rig) 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 Garrett 40 (masthead rig)?

The Offshore Special Regulations cap a storm jib at 5% of I squared (12.5 m² here) and a trysail at 17.5% of P × E (11.4 m²). That makes our Maxi (12 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.
