Boat Cover for 16-18.5 ft Boats - Heavy Duty Waterproof Trailerable

Our review of this boat cover finds it best suited for owners of V-hull fishing boats, bass boats, runabouts and pro-style craft who need dependable year-round protection on a trailer or in storage. The single biggest reason to buy is the protective construction: a long-lasting canvas fabric with a waterproof PVC coating and anti-UV finish that is designed to resist fading, tearing and cold cracking while providing a snug fit for boats up to 16 ft-18.5 ft long and 94 in beam. It is a practical, value-focused option when full coverage is a priority.

Key Features

• Universal fit: Fits a wide range of V-hull fishing boats, tri-hull runabouts, bass and Fish & Ski boats up to 16 ft-18.5 ft long and 94 in wide, reducing the need to search for a custom cover.
• Waterproof PVC coating: The water-resistant finish repels rain and helps prevent staining, making outdoor storage and trailering less risky for gear and interior surfaces.
• UV resistant: An anti-UV treatment reduces fading and material degradation when the cover is used for extended outdoor exposure.
• Secure hem and straps: A heavy-duty elastic cord around the hemline plus integrated buckle and adjustable straps provide a snug, trailerable hold in wind or transit.
• Easy maintenance: The water-repellent surface cleans with a hose, so routine care is quick and keeps the cover looking serviceable.
• Portable storage: Includes a storage bag so the cover can be stowed compactly when not in use.

Who It's For

This cover is aimed at recreational boat owners who trail their craft or need off-season protection without spending on a bespoke solution; anglers and weekend boaters with V-hull and pro-style bass boats will appreciate the fit range and strap system for trailering. The waterproof and UV-resistant features make it a solid choice for those who park outdoors frequently.

Those who need the thickest, longest-lasting marine-grade fabric or who require a guaranteed multi-year heavy-duty warranty should look elsewhere or consider upgrading to a higher-weight marine cover. Also check the manufacturer size chart carefully if your boat has an unusual cabin or tower profile that could change fit requirements.

Frequently Asked Questions

Will this cover fit a bass boat 17 ft long?
The cover is designed for boats up to 16 ft-18.5 ft long and a beam up to 94 in, so a 17 ft bass boat within that beam should be compatible; check the size chart for exact fit.

Is the cover fully waterproof in heavy rain?
The PVC coated fabric is water-resistant and repels rain, but some users report water pooling in low spots, so a support pole is recommended to prevent accumulation.

Can it be used while trailering?
Yes, the heavy-duty elastic hem and adjustable buckle straps make it suitable for trailering when properly secured.
