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 42 footer carries about 41.0 m² of mainsail and 52.0 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 42 ft we use Optimum Cruise 398 OC (9.9 oz) or C-Breeze 391 CB (9 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.

Sail prices follow sail area, not boat length. A typical 42 ft boat carries about 41.0 m² of mainsail and 52.0 m² of 130% genoa, but a tall-rig or performance boat carries more, and a fractional rig has a bigger main and a smaller genoa. That is why we price every boat from its own rig dimensions (I, J, P and E).

We match the cloth weight to the boat's length using Dimension-Polyant's guide. For a 42 ft boat that is Optimum Cruise 398 OC (9.9 oz) or C-Breeze 391 CB (9 oz).
