YSPACE Boat Cover 17-19ft — Best All‑Season Protection
The YSPACE cover uses durable 1200D Oxford fabric with a four-layer construction, including anti-UV coating and a waterproof layer. It provides robust protection against sun, rain, snow, and cold cracking. Sealed seams help prevent leaks during winter storage, and reinforced stitching reduces wear at bow and stern. The windproof design relies on 11 adjustable straps and an elastic hem, while reflective strips improve visibility in low light. Best for larger, trailerable bass boats and runabouts stored outdoors over winter, with a caution: ensure proper strap tension to avoid fluttering in high wind.
SavvyCraft Waterproof Mainsail Boom Cover 13′-14′
Designed for 13-14 ft booms, this cover features UV-protective marine polyester with a PU backing, plus a heavy-duty zipper at the mast end and a storm flap to protect the zipper. Adjustable webbing straps with buckles provide a neat, snug fit along the bottom edge. It uses triple-layered hems and double stitching for durability, and includes a silver UV reflective layer at the mast area to reduce heat buildup. This option is best for sailboats with mid-length booms stored during winter; avoid if your boom length falls outside the 13-14 ft range, as fit may be compromised.
iCOVER Trailerable Boat Cover 17′-19′
The iCOVER model fits boats up to 19 ft long with a beam up to 96 inches. It is waterproof and UV resistant, built from canvas with a PVC coating to resist tearing and fading. The design emphasizes a full-coverage fit with an elastic hem and integrated tightening system with buckles for quick installation and removal. This makes it suitable for winter storage when a secure, weatherproof cover is essential. Better for boats that require a broad, forgiving fit; consider checking the size chart to ensure your exact hull configuration falls within the recommended range.
Che Yi Bao Mainsail Boom Cover 10′-11′
Che Yi Bao’s 800D fabric cover offers a snug fit for 10-11 ft mainsails, with a polyurethane back coating for waterproofing and UV protection. A large zipper and fixed rope with an ABS carabiner support secure installation, while three-layer hems with double-stitched seams reinforce durability. An edge feature is a solid dyeing process that preserves color under sun and winter exposure. Best for smaller mainsails or compact sailboats; limitation includes fit precision for booms significantly outside the 10-11 ft range.
Buying Guide: Key Factors For Winter Boat Storage Covers
- What size is your boat? Measure overall length and beam to select a cover with the correct fit range. Universal trailers will typically cover a broad range, but near-limit gaps can cause tearing or leaks in winter conditions.
- What climate will you face? Look for four-layer or multi-layer constructions with waterproof coatings and UV resistance to withstand sun, snow, and freezing rain.
- How important is a snug fit? Features like elastic hems, adjustable straps, and buckles help minimize wind uplift and water intrusion. Choose models with reinforced seams in high-stress zones.
- Is ventilation needed? Some covers offer breathable materials or vented designs to reduce condensation buildup inside the cover, reducing mildew risk.
- Is easy installation a priority? Zippers, storm flaps, and quick-release buckles simplify setup, especially if you store the boat or move it during winter.
Practical Tips For Winter Storage
- Store on a level, dry surface to prevent deforming the hull and frame.
- Regularly check strap tension and seam integrity during seasonal weather changes.
- Use a breathable inner cover or extra fenders to avoid abrasion while protecting against harsh conditions.
