What it is
Canvas covers include mainsail covers, dodgers, biminis, winch covers and other protective fabric items. Sail bags are heavy-duty bags designed to store and protect sails when not in use. These items are typically made from marine-grade fabrics with UV-resistant properties. Quality covers and bags protect expensive sails and equipment from UV damage, moisture, dirt and physical wear.
What it does
Canvas covers protect sails and equipment from the sun's damaging UV rays, which can dramatically shorten the lifespan of expensive sails. Mainsail covers protect the sail when furled or flaked on the boom. Dodgers and biminis provide crew protection and comfort while sailing. Sail bags keep stored sails clean, dry, and protected from UV exposure and pests. Winch covers protect moving parts from salt and grit. These protective items extend the life of gear that would otherwise degrade rapidly in the marine environment.
Why it matters
UV damage is the number one enemy of sails. An uncovered sail can lose significant strength in just one season of sun exposure. Canvas covers are a fraction of the cost of new sails, making them an obvious investment. Dodgers and biminis make sailing more comfortable and protect crew from sun exposure, making longer passages more pleasant. Proper storage in sail bags prevents mildew, keeps sails clean and protects them from chafe and rodent damage during off-season storage.
General Maintenance
Inspect canvas items at the beginning of each season for tears, worn stitching, broken zippers and UV damage. Repair snaps and fasteners promptly as loose sail covers can flog in the wind and lead to further damage. Rinse hardware such as zippers and grommets with freshwater after exposure to saltwater to prevent corrosion. Clean canvas covers several times per season with mild soap and fresh water, allowing them to dry thoroughly before storage. Check and lubricate zippers regularly with zipper lubricant or wax. Repair small tears and loose stitching promptly before they become major failures. Store canvas items clean and dry during the off-season. Replace covers showing significant UV fade, as this indicates weakened fabric. Treat with fabric waterproofing spray if water no longer beads on the surface.
Common Issues
- Zipper failures from salt corrosion and UV damage
- Stitching deteriorating from UV exposure and chafe
- Snaps pulling out from fabric degradation
- Mildew growth when stored damp
- UV degradation causing fabric to weaken and tear
- Battens or sail hardware wearing holes through covers
- Hardware corroding and staining fabric
- Improper fit allowing covers to flog
