Buying Guide for Boat Tarps and Winter Storage Covers
Choosing the right boat tarp for winter storage involves multiple factors to ensure effective protection and long-term durability.
Material Thickness and Durability
The thickness of tarps, measured in mils, indicates robustness. Tarps around 5 to 20 mils thick provide varying degrees of protection. For winter storage, thicker tarps (10 mils and above) are preferable to resist punctures, tears, and harsh weather elements.
Weather and UV Resistance
Look for tarps with confirmed waterproof, UV-resistant, and temperature-resistant features. These properties protect your boat from sun damage, moisture penetration, freezing conditions, and wind damage.
Reinforced Corners and Edges
Reinforced corners and double-stitched or heat-sealed hems increase the tarp’s lifespan by preventing tears during strong winds or heavy snow loads. Plastic or fabric edging and polyethylene rope reinforcements provide additional strength.
Grommet Quality and Placement
Durable grommets made from rust-resistant metals like aluminum or steel allow secure tie-downs. Grommets spaced every 18 to 24 inches provide flexibility in securing the cover tightly around the boat to prevent shifting.
Fit and Size Considerations
Choose tarp sizes slightly larger than your boat dimensions to ensure full coverage. Custom or semi-custom tarps offer a more tailored fit but universal models with elastic cords or straps can adapt securely to various boat shapes.
Support Systems
Consider using cover support poles to avoid sagging and pooling water or snow on the tarp surface. These poles maintain a dome shape for better runoff and help prolong the tarp’s life and your boat’s condition.
Storage and Ease of Use
Look for tarps with storage bags for convenience, and features like adjustable straps or buckles that simplify installation and removal, especially in cold winter months.
Taking all these factors into account will help you select a high-quality boat tarp that offers optimum protection and durability for your winter storage needs.
