Choose your sailcloth
- Challenge Atlantic 10.38 oz: value woven polyester (Dacron). Our lowest price and a good all-round cruising cloth.
- Challenge Fastnet 10.88 oz: a higher-grade woven polyester that holds its shape for longer. A better pick for a genoa that stays on the furler year-round.
- Challenge Palma 24 White: a cruising laminate with glued seams. Lighter, points higher and holds its shape best; it needs more care with flogging.
