From A$1,625.80 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$1,790.80 with 4 full battens. C-Breeze, the long-life cloth, starts at A$2,183.50. Every mainsail is cut to the Koopmans Kustvaarder 28 rig (P 8.45 m, E 3.55 m) with two reefs.
We build 110% to 150% LP for the standard rig (I 9.80 m, J 3.20 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$1,383.80.
A Size 1 (37 m²) asymmetric suits the Koopmans Kustvaarder 28 fore-triangle. It starts at A$1,214.40, or A$1,774.30 with a dousing sock.
The Offshore Special Regulations cap a storm jib at 5% of I squared (4.8 m² here) and a trysail at 17.5% of P × E (5.3 m²). That makes our Small (4.5 m²) storm jib the right size. No stock trysail is small enough for this rig, so we quote one to fit.
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.
