The North Sails DB-3 Contender mainsail, originally developed for consecutive class champion Matt Mulder, is designed for versatility. It's tailored for CST old-style masts but has also performed well on C Tech and new CST masts. Constructed from 3.8 Polykote Dacron, a lightweight and durable sailcloth, it features a short leech length at 5.950 meters, ideal for aging crews. Recommended for crew weights ranging from 75 to 105 kg, the DB-3 proves its adaptability on the water.
