NEVERLAND Pontoon Boat Cover 17-20 ft
This cover is best for boat owners who trailer their pontoon and store it outdoors. It uses ripstop marine-grade Oxford cloth that is waterproof, with anti-aging properties to resist sun and wind exposure. The bottom hem includes an elastic cord for a 360-degree fit, and 15 adjustable straps with reinforced buckles help secure the canopy during travel. Choose this if you frequently trailer and need dependable, all-around protection. A limitation is the number of straps; for very windy locations, additional tie-down methods may be beneficial.
RVMasking Pontoon Boat Cover 21′-24′
Best for pontoon owners seeking maximum wind resistance and robust waterproofing. This cover uses 1400D middle and 900D ends, designed to resist tearing at high-stress points. It features a dual-layer waterproof coating rated for strong rain exposure and UV protection. The 12,000 Pa+ waterproof standard helps keep interior dry. It’s a solid pick for long-term outdoor storage or frequent inclement-weather exposure. Pro tip: consider a support pole to reduce water pooling on the cover’s surface.
NEVERLAND Pontoon Boat Cover 21-24 ft
Ideal for larger pontoons, this blue Neverland cover provides 360-degree protection with 18 adjustable straps and reinforced buckles. The ripstop fabric offers waterproofing and anti-aging benefits, helping it resist sun and moisture for extended lifespans. Best for boaters who need a roomy fit and strong security during trailering. The main caveat is that the heavier fabric may require more effort during installation compared to lighter-weight covers.
DeckMate 20′ – 22′ Gray Pontoon Cover
Best for budget-minded buyers who still want solid protection and warranty. DeckMate covers use durable 600D polyester with fade and stain resistance, and they come with a three-year full replacement warranty. The fabric is strong enough for regular use, though it may not be as heavy-duty as 900D or 1400D options. Choose this if you want a reliable cover with strong warranty coverage without paying premium prices.
Lanlelin Heavy Duty 18′-20′ Pontoon Cover
This is a cost-conscious option suitable for boats 18′ to 20′ long, with a 98″ beam. It uses 900D marine-grade polyester and reinforced seams to withstand regular exposure. It includes elastic shock cords and adjustable straps for a snug fit. Best for budget-focused buyers who still want solid protection. A limitation is that it may not offer the same long-term weatherproof performance as higher-denier fabrics in extreme conditions.
Buying Guide
Key considerations when choosing a pontoon boat cover:
- Boat size and beam: Ensure the cover matches your pontoon’s length and width for a proper seal and fit.
- Fabric denier and layers: Higher denier (e.g., 900D, 1200D, 1400D) tends to offer better durability and wind resistance, but may be heavier and cost more.
- Waterproofing vs. breathability: A waterproof exterior helps with rain, while interior coatings prevent moisture buildup; some models advise adding a support pole to reduce pooling.
- Fastening system: Look for multiple adjustable straps and reinforced buckles for secure trailering; elastic hems provide 360-degree coverage.
- Warranty and replacement: A longer warranty indicates confidence in durability; consider models with full replacement offers.
- Storage and maintenance: Darker colors hide dirt; lighter fabrics may require more cleaning, while anti-stain properties help keep appearance.
Working With Size and Fit
Always measure your pontoon’s deck length and beam width. If you’re between sizes, opt for the larger model to ensure full coverage without pulling at seams. Trailering requires a snug, wind-resistant fit, so pay attention to the number of straps and the presence of reinforced buckles in the product details.
Maintenance Tips
- Rinse covers after exposure to saltwater or dirt to extend life.
- Dry completely before storage to prevent mold and mildew.
- Inspect straps and buckles for wear and replace any frayed components promptly.
FAQ
- What length cover do I need for a 20-foot pontoon?
Look for covers described as 20′ to 22′ or 19′ to 21′ depending on the brand, ensuring the beam width matches as well. - Are heavier fabrics worth the extra cost?
For frequent trailering or exposure to strong winds, higher-denier fabrics (900D–1400D) generally offer longer life and better protection. - Should I use a support pole with a pontoon cover?
Yes, a support pole reduces water pooling and improves airflow, which helps prevent moisture damage. - What warranty should I expect on pontoon covers?
Many models offer 3-year warranties or full replacement guarantees; this reflects durability expectations. - Can I use a pontoon cover year-round?
Yes, but ensure the fabric suits your climate and add ventilation if you store indoors or in high humidity areas. - How do I choose between 17-20 ft and 21-24 ft covers?
Match the cover to your boat length and beam. If your pontoon sits between sizes, prefer the larger option to avoid gaps and stress at seams.
