YSPACE Boat Cover 17-19ft, 1200D Heavy Duty Waterproof
The YSPACE cover uses marine-grade 1200D Oxford fabric with a four-layer structure, including anti-UV coating, 12,000 Pa waterproof coating, a heavy-duty base, and PU coating. It is designed to shield from sun, rain, snow, and cold cracking. Seams are sealed with waterproof tape for durability. This long-lasting option is best for larger, trailerable boats that face frequent road storage and exposure to seasonal weather.
Best for: Bass boats and runabouts that require robust weatherproofing and trailering protection. Consider this if you need strong seam reinforcement and reflective safety features for night storage or towing.
Limitation: The weight of the 1200D fabric may require assistance for frequent handling or install/removal on very large boats.
SavvyCraft Waterproof Mainsail Boom Cover (13′-14′) Navy
This cover features UV protection with solution-dyed, fade-resistant marine polyester and a PU-coated back. A heavy-duty #10 zipper at the mast end, storm flap with Velcro, and adjustable tie-down straps ensure a secure fit. The triple-layered hem and double stitching reinforce durability, while a UV-reflective layer helps manage heat near the mast. It’s well-suited for sailboats that need reliable protection from sun and weather while not adding excessive weight.
Best for: Sailboats with 13-14 ft booms that require a snug, protective fit and long-term UV resistance. Choose this if you want reinforced seams and durable finishing details for frequent winter storage.
Caution: Ensure the zipper area remains dry during installation to prevent zipper corrosion or water ingress over time.
iCOVER Trailerable Boat Cover (17′-19′)
The iCOVER trailerable cover is designed to fit a range of boats up to 19 ft long and 96 inches wide. It uses waterproof and UV-resistant canvas with a PVC coating for year-round use, including protection against tearing, fading, and cold cracking. A heavy elastic hem with integrated buckles and adjustable straps provides a secure, snug fit. This option emphasizes broad compatibility and practical ease of use for boats stored across multiple seasons.
Best for: Boat owners who want a versatile, universal fit for various V-hull and bass boats during winter storage. Choose this if you prioritize ease of installation and a snug, protected fit for a broad boat range.
Limitation: Check the size chart to ensure accurate fit for atypical beam measurements.
GUDWAT 1200D Mainsail Boom Cover (7′-8′) Black
GUDWAT offers a 1200D mainsail boom cover with UV protection and a PU-coated back. The four-layer waterproof structure, plus marine stitching and a soft cotton lining, resists water intrusion and reduces friction near the mast area. It’s designed to withstand sun exposure and winter moisture, providing durable protection for smaller mainsails.
Best for: Sailboats with 7-8 ft booms that need sturdy, long-lasting protection in harsh winter conditions. Choose this if you want an extra-soft interior layer to cushion the mainsail during storage.
Limitation: For larger sails, this model may require a larger size or an alternative cover with extended dimensions.
Che Yi Bao Mainsail Boom Cover (10′-11′)
Che Yi Bao’s mainsail boom cover uses an 800D thickened polyester with a PU back for waterproofing and fast drying. A large zipper, fixed rope, and ABS carabiner ensure a snug fit to the mainsail. Three-layer hems and double-stitched seams enhance durability, while solution-dyed fabric resists color fade under strong sun. This model emphasizes a secure fit and long service life for mid-sized mainsails.
Best for: Boats with 10-11 ft mainsails that require a tight, weather-resistant cover with robust stitching. Choose this if you value a snug fit and color stability.
Caution: Ensure proper zipper protection during storage to prolong zipper life in cold climates.
Buying Guide: Key Considerations For Winter Sailboat Covers
Material and durability: Look for high-denier fabrics (1200D or similar) with multi-layer protection and UV resistance. This reduces sun damage, moisture intrusion, and wear from wind-driven debris during storage.
Fit and size: Measure boat length, beam, and mast height. Choose trailerable or universal fits with adjustable straps and elastic hems for a secure, windproof seal.
Seams and reinforcements: Sealed seams and double or triple-stitching at stress points (bow, stern, mast) extend life and prevent leaks during periods of storage or transport.
Ventilation and moisture control: While winter storage emphasizes protection, some covers include breathable fabrics or venting concepts to reduce mildew and condensation buildup.
Ease of use: Consider zippers, storm flaps, and quick-release straps. Covers that are easier to install and remove save time during seasonal setup and takedown.
Weather adaptability: For regions with snow, wind, and freezing temperatures, select covers with enhanced waterproofing, snow shedding design, and reflective strips for nighttime visibility.
