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.

Introducing the Contender MAX-4 Mainsail, a cutting-edge cross-cut laminate sail. It excels across the entire wind spectrum, from harnessing power in light breezes to optimizing efficiency in strong winds with minimal drag. Achieving this versatility is made possible by leveraging the directional strain of its fabric to maintain precise horizontal sections. Its higher modulus cloth particularly enhances downwind performance, especially in winds exceeding 10 knots, where class regulations permit free pumping.
