Pontoon Boat Cover 17-20 ft with Motor Cover - Heavy Duty Windproof

Our review of the RVMasking pontoon boat cover finds it best suited for owners of 17 to 20 ft pontoon boats who need a rugged, weatherproof solution that resists wind and keeps water out. The single biggest reason to buy is its reinforced 1400D fabric in the midsection combined with a dual-layer 12000 PA+ waterproof treatment, which together target the two most common failure points for covers: wind tearing and moisture penetration. Installation is straightforward and the included motor/storage bag is a practical add-on.

Key Features

• 1400D reinforced midsection: Extra-thick fabric in the stress-prone middle reduces the chance of wind ripping and improves long-term durability.
• 12000 PA+ dual-layer waterproof: Both outer and inner coatings repel water and stop seepage, helping prevent rain and snow damage to the boat interior.
• Full fit for 17-20 ft pontoons: Sized to fit boats in that length range and beam widths up to 102 in for a snug overall fit.
• 12 adjustable tie-down straps: Quick-release buckles and reinforced strap connections keep the cover secured during strong winds.
• Motor cover / storage bag included: The 2-in-1 bag protects the motor when not in use and stores the cover compactly when stowed.

Who It's For

This cover is aimed at pontoon owners who need a heavy-duty, wind-resistant cover for seasonal storage or offseason protection, especially in exposed mooring or driveway situations. If you prioritize reinforced fabric in high-stress areas and a waterproof interior layer, this cover addresses those needs directly.

Those who should look elsewhere include owners of pontoons smaller than 17 ft or larger than 20 ft, or buyers who need a custom-fit cover for unusual accessories. Also, if you rely entirely on a single-layer light fabric for short-term, low-cost protection, the heavier materials here may be more than you require.

Pros & Cons

Pros

• Sturdy windproof design thanks to the 1400D reinforced midsection for better tear resistance.
• Excellent wet-weather protection from the dual-layer 12000 PA+ waterproof treatment.
• Secure installation with 12 tie-down straps and all-around elastic hem for a 360 degree fit.
• Includes a multi-use storage bag that doubles as a motor cover for added convenience.

Cons

• The heavier fabric makes the cover less compact and a bit harder to handle for one person when installing or folding.
