Common questions
How do I know what size boat cover to buy?
Measure your boat’s overall length and the width at the widest point. Also consider the height of accessories like windshields. Compare your measurements to the manufacturer’s size chart. A cover that is too small will be tight, while one too large can flap and pool water.
Can a heavy duty boat cover protect against all weather?
Most heavy duty covers are designed to handle sun, rain, and snow. They are typically water resistant or waterproof. However, no cover can withstand extreme storms without proper installation. Always secure the cover tightly and use a support pole to prevent water accumulation.
What is the difference between water resistant and waterproof?
Water resistant covers can repel light rain but may leak under heavy rain or standing water. Waterproof covers have a coating or laminate that blocks water entirely. For long term outdoor storage, a waterproof cover is recommended. Check the product specifications for waterproof ratings.
How often should I replace my boat cover?
The lifespan of a boat cover depends on the material and exposure. High quality covers like Sunbrella can last 10 years or more. Polyester covers may last 3 to 5 years. Regularly inspect your cover for tears, fading, or weakening seams and replace it when it no longer protects your boat.
Can I trailer my boat with a cover on?
Some covers are specifically designed for trailering, with reinforced seams and tie down loops. Check if the cover comes with a trailering kit. If not, you may need to add extra straps. Never assume a cover is safe for trailering without proper attachments.
What are the benefits of a breathable boat cover?
Breathable covers allow air to circulate, preventing condensation and moisture buildup. This reduces the risk of mold, mildew, and rot. They are especially beneficial if you store your boat in a humid environment or for long periods.
How do I clean and maintain my boat cover?
Clean your cover periodically with mild soap and water. Avoid using harsh chemicals or power washers that can damage the fabric. Let it dry completely before storing. Apply a fabric protector if recommended by the manufacturer to maintain UV resistance.
Are custom fit covers worth the extra cost?
Custom fit covers are tailored to your boat’s exact dimensions, providing a snug fit that reduces flapping and wear. They often include extra features like mirror pockets or windshield reinforcements. If you have a common boat model, a custom cover can be worth the investment for better protection.
The verdict
For most boat owners, the Classic Accessories OverDrive offers the best combination of durability, UV protection, and fit. It strikes an excellent balance between price and performance. If you face extreme sun exposure and want premium fabric, invest in a Taylor Made Sunbrella cover.
