YSPACE Boat Cover 17-19ft
Best for trailerable boats up to 96″ wide, this cover uses durable 1200D fabric with a four-layer construction: anti-UV coating, waterproof layer, heavy-duty base, and PU coating. It provides robust protection against sun, rain, snow, and cold cracking. Sealed seams prevent leaks, while reinforced stitching at bow and stern reduces wear. The 11 adjustable straps with an elastic hem offer windproof stability and night visibility through reflective strips. Suitable for trailering and long-term storage, it keeps a hull protected in mixed winter conditions.
Best for: boaters who trailer or store a long boat and need strong, weatherproof coverage. Choose this if you demand durable fabric and a secure, wind-resistant fit. Caution: heavier fabric may require more effort to install and remove.
SavvyCraft Mainsail Boom Cover 13′-14′ Navy
Best for sailboats with medium-length booms, this cover uses UV-protected marine-grade polyester with a PU-coated back to resist sun and moisture. A heavy-duty #10 zipper at the mast end, storm flap, and Velcro closure help protect against water intrusion. The triple-layered hem and double stitching reinforce the edges for enduring winter use. The extra silver UV-reflective layer at the mast area helps reduce heat stress. This is a solid option for maintaining mainsail fabric integrity during cold, windy storage periods.
Best for: protecting mainsails from UV exposure and moisture while stored. Choose this if you want reinforced seams and a secure zipper system. Caution: ensure the zipper area remains free of debris during off-season storage.
iCOVER Trailerable Boat Cover
Best for versatile boat types up to 17-19 ft and 96″ beam, this universal cover features waterproof and UV-resistant canvas with a PVC coating. It emphasizes year-round protection against tearing, fading, wetting, and cold cracking. A heavy-duty elastic hem, integrated buckles, and adjustable straps simplify installation and removal. This option is practical for owners who want a flexible, all-season cover capable of handling winter moisture and wind while stored.
Best for: boaters seeking a universal fit with simple setup and reliable water resistance. Choose this if frequent store-and-go handling is needed. Caution: verify size against your exact beam to avoid a loose fit in deep winter winds.
Che Yi Bao Mainsail Boom Cover 10′-11′
Best for smaller mainsails, this 800D thickened sail cover uses a polyurethane heat-reflective coating for waterproofing and fast-drying performance. A large zipper, fixed rope, and ABS carabiner help ensure a snug fit, allowing quick setup and minimal wind disruption while waiting for use. The triple-layer hem and double-stitching improve durability for winter storage periods, and the edges resist damage from prolonged exposure.
Best for: compact mainsails and easy installation. Choose this if you need a snug, low-profile cover with solid fastening. Caution: ensure the fit matches your sail dimensions to avoid gaps that let moisture in.
GUDWAT 1200D Mainsail Boom Cover 7′-8′
Best for compact mainsails, this 1200D fabric cover offers waterproof and UPF 50+ sun protection with a four-layer coating and marine-grade stitching. The soft cotton lining cushions the sail against abrasion and reduces friction at the mast area, helping to minimize heat-related weakening during extended winter storage. Extra-strong stitching and a snug fit support durability in harsh winter conditions.
Best for: protecting smaller sails from sun and moisture while stored. Choose this if you prioritize sun protection and a cushioned interior. Caution: confirm your sail length matches the cover size to ensure full coverage.
Buying Guide: Key Considerations For Winter Sailboat Storage
- Size and fit matters: Measure beam width, hull shape, and boom length. A too-loose cover can flap in winter wind, while a too-tight cover may stress seams. Look for covers with adjustable straps and elastic hems.
- Material and durability: Heavy-duty 1200D or similar fabrics offer superior abrasion resistance and waterproofing. Four-layer constructions with UV coatings prolong life under sun and snow. Avoid thin, single-layer fabrics for long-term storage.
- Waterproofing and UV protection: For winter storage, waterproof layers prevent moisture infiltration, while UV protection minimizes sun damage during any sunny days. Reflective strips improve visibility during late-season storage near roads.
- Ease of use: Quick-release straps, buckles, and zipper systems facilitate seasonal removal and reattachment. Consider covers with storm flaps to guard zippers and openings.
- Ventilation: Some designs include breathable fabrics or venting features to reduce condensation inside the cover, lowering mold risk during damp winters.
- Compatibility: Ensure the cover fits your boat type (V-hull, runabout, bass boat, or sailboat mainsail area). Universal covers are convenient but verify dimensions match your boat.
- Storage and care: Check whether a storage bag is included and how to clean or dry the cover after harsh weather.
