Frequently asked questions
How do I measure my boat for a cover?
Measure the centerline length from bow to stern and the beam width at the widest point. Add 6 to 12 inches for overlap. Check the manufacturer’s size chart for the recommended cover size.
What is the best fabric for a heavy duty boat cover?
600 denier polyester with a waterproof coating is a good choice. It offers durability and water resistance. Acrylic is breathable but less waterproof. For extreme weather, a 3 ply fabric is recommended.
Can I trailer my boat with the cover on?
Yes, if the cover is designed for trailering. Look for reinforced straps and a tension system. Some covers are not meant for highway speeds and can rip.
How do I keep water from pooling on the cover?
Use a cover with a center support pole or a built in pole system. Tighten the cover so it is snug. Adding a small pool noodle under the cover can also help create a slope.
Are boat covers waterproof?
Most heavy duty covers are water resistant or waterproof. Check the specifications. A waterproof coating and sealed seams provide the best protection. Some covers are breathable and may allow water vapor to escape.
How do I clean and store my boat cover?
Use a mild soap and water to clean. Rinse thoroughly and let it dry completely. Fold it loosely and store in a dry place. Avoid storing a wet cover as it can lead to mildew.
What is the difference between a mooring cover and a trailering cover?
A mooring cover is designed for boats kept in the water. It is often breathable to prevent condensation. A trailering cover is built for highway speeds with more reinforcement and a tighter fit.
How long should a boat cover last?
With proper care, a heavy duty boat cover can last several years. Exposure to sun and harsh weather will shorten its life. Regular cleaning and reapplying waterproofing can extend durability.
