Optimum Cruise sailcloth, full batten mainsail, standard build.
What sets the price
Sail area. Price follows the size of the sail, which comes from your boat's rig (I, J, P and E). A typical 20 footer carries about 11.5 m² of mainsail and 11.0 m² of 130% genoa.
Sailcloth. Both cloths are woven polyester (Dacron) from Dimension-Polyant, the German sailcloth maker. Optimum Cruise is the value choice for coastal and weekend cruising. C-Breeze is a tighter weave that resists stretch and holds its shape for longer, for sails that work hard or go offshore. At 20 ft we use Optimum Cruise 248 OC (6 oz) or C-Breeze 241 CB (5 oz).
Battens. Full battens (4) hold the sail's shape and help it last. The 3 leech + 1 full head batten option costs a little less.
Genoa size. We make furling genoas from 110% to 150%. Most cruising boats carry about 130%; a smaller genoa costs less.
Build time. Standard is about 4 weeks. Express (about 2 weeks) adds 8%; economy (about 8 weeks) takes 5.5% off.
What's included
Mainsail: cloth weight matched to your boat, two reef points with low friction rings, cunningham, stacked reinforcement patches, Dyneema leech and foot lines, battens, sail bag and a 12-month warranty.
Furling genoa: Sunbrella UV cover on the leech and foot in your choice of colour, foam luff pad, luff tape to suit your furler, stacked reinforcement patches, sail bag and a 12-month warranty.
After you order, a sailmaker checks your measurements before anything is cut. If your numbers change the price, we tell you first and you can cancel for a full refund.
