Schock 40 sails: questions
How much is a new mainsail for a Schock 40?
From A$4,236.10 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$4,478.10 with 4 full battens. C-Breeze, the long-life cloth, starts at A$5,464.80. Every mainsail is cut to the Schock 40 rig (P 13.55 m, E 5.41 m) with two reefs.
What size genoa does a Schock 40 need?
We build 110% to 150% LP for the standard rig (I 12.91 m, J 4.10 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$2,678.50.
What size spinnaker fits a Schock 40?
A Size 5 (64 m²) asymmetric suits the Schock 40 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 Schock 40?
The Offshore Special Regulations cap a storm jib at 5% of I squared (8.3 m² here) and a trysail at 17.5% of P × E (12.8 m²). That makes our Large (7.5 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.
