From A$2,629 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$2,786.30 with 4 full battens. C-Breeze, the long-life cloth, starts at A$3,348.40. Every mainsail is cut to the Seidelmann 37 (short mast) rig (P 12.80 m, E 3.35 m) with two reefs.
We build 110% to 150% LP for the standard rig (I 14.17 m, J 4.66 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$3,348.40.
A Size 7 (83 m²) asymmetric suits the Seidelmann 37 (short mast) fore-triangle. It starts at A$2,352.90, or A$3,227.40 with a dousing sock.
The Offshore Special Regulations cap a storm jib at 5% of I squared (10.0 m² here) and a trysail at 17.5% of P × E (7.5 m²). That makes our Extra Large (9.5 m²) storm jib and Small (6.1 m²) trysail the right sizes.
Measure I, J, P and E and compare them with the rig table. We confirm every measurement with you before the sail is cut.
For a race programme, a Sydney to Hobart or a bluewater expedition, our sister loft Kraken Sails designs laminates, membrane sails and storm wardrobes for the hard end of sailing.
