It includes rust-proof grommets every 19.5 inches and reinforced corners for secure binding, making it suitable for boat storage and travel.

Caution: measure carefully to account for heat-sealed edges that may slightly alter final dimensions.
Lanlelin Heavy Duty Jon Boat Cover
Lanlelin’s cover is designed for 14′1″–17′ boats, including V-hull configurations. It uses 600D marine-grade polyester with UV resistance and reinforced vulnerable areas. Triple-folded, double-stitched seams increase durability, while built-in reinforcement loops and selective tightening systems help prevent wind from lifting the cover. Best for boaters needing a robust, long-lasting outdoor cover. Limitation: ensure correct size matching with your boat’s exact length for a snug fit.

iCOVER offers a universal trailerable cover for boats up to 16–18.5 ft with a 94″ beam, suitable for V-hull, bass, and runabout models. It features a water-resistant PVC coating and anti-UV finish to mitigate sun damage and tearing. A full-coverage fit is achieved with an elastic hem and adjustable straps. Best for seasonal trailers or transport where quick setup and removal matter. Caution: verify the size chart to avoid a loose fit that may blow off in wind.
FOCEAN 1200D Boat Cover
FOCEAN uses 1200D marine-grade fabric with ripstop and an anti-UV top layer, paired with interior PU coating for moisture resistance. Fully sealed seams withstand heavy rain and maintain waterproofing. The product includes 24-month support and is designed for bass, V-hull, and runabout boats. Best for long-term storage in wet climates. Limitation: heavier fabric may be more cumbersome to handle for smaller boats.
Mockins Large Waterproof Boat Cover
Mockins offers a 20–22 ft trailerable cover with a 100″ beam, tailored for larger bass, fishing, or runabout boats. Constructed from 600D polyester with wind-stable design, it includes tie-down straps and ratchets for secure in-transit protection. Best for larger boats needing reliable road-ready protection. Caution: ensure the cover length aligns with your boat’s exact measurement to avoid overhang or gaps during travel.
Buying Guide: Key Purchase Considerations
What size is right for your boat? Measure overall length, beam, and hull configuration (V-hull, Jon, bass). Select a tarp that slightly exceeds length and width for full coverage, accounting for fasteners and straps.
What material offers the best protection? Look for heavy fabrics (12–16 mil) with reinforced edges and sealed seams. For wet climates, consider UV protection and a moisture barrier to prevent mold and mildew.
How important are grommets and ties? Grommets spaced regularly and reinforced corners reduce tearing risk and help you secure the tarp during snow or wind.
Will it be stored outdoors year-round? Prioritize abrasion resistance, fade resistance, and a fabric with proven waterproofing and breathability to prevent moisture buildup under the cover.
Is trailer use a factor? For trailer-ready covers, ensure a snug fit with adjustable straps, buckles, and an elastic hem to resist shifts at highway speeds.
Practical Tips For Installing And Maintaining
- Dry your boat thoroughly before covering to minimize moisture entrapment.
- Remove or secure loose items that could snag on the tarp edges.
- Periodically check straps and seams for wear, especially after storms.
- Store tarps in a cool, dry place when not in use to extend life.
FAQ
- Q: What is the best tarp material for winter boat storage? A: A heavy-duty fabric with reinforced seams and a water-resistant/UV-treated coating, such as 1200D or 600D polyester, that resists tearing and moisture.
- Q: How should I measure my boat for a tarp? A: Measure overall length, beam width, and hull type (V-hull, Jon, bass). Choose a tarp that covers beyond those dimensions for a secure fit.
- Q: Can tarps be used for trailering in winter? A: Yes, but select a trailerable cover with an elastic hem and adjustable straps to prevent wind from lifting the cover.
- Q: Do tarps prevent snow buildup on boats? A: They help shed precipitation, but periodic brushing and proper venting can reduce snow load on the cover itself.
- Q: How long can a tarp stay on a boat in winter? A: As long as weather conditions permit and the tarp remains properly secured and dry, with periodic inspections to prevent damage or moisture buildup.
- Q: Should I buy a larger tarp than my boat measurements indicate? A: Yes, to ensure full coverage, allow extra margin for fasteners, tie-downs, and wind exposure.
