Sew it yourself! 40’ UV Insignia Suncover Kit contains everything needed to add a sacrificial sun cover to a furling sail. Protect with the best! Sunbrella is the most popular choice, but the fabric is heavy. Insignia UV Dacron is a much better choice for boats under 30 feet, as it is lighter.
The width of the sacrificial strip should span the exposed edge of the sail when rolled onto the forestay (add 6” for sloppy furling). If the sail is not available for measurement in its furled state, the table below can be used to determine width.
