Be Prepared

One thing you need to remember when using a tarp to cover your boat is that these are not built for strength. A custom canvas boat cover can handle some wear and tear. You need a gentler touch with a tarp. That means you need to be aware of the sharp edges on your boat. Watch out for the windshield frame corners. If you have an antenna mounts keep an eye on them as well.

Anything with sharp edges could cause a tear in your tarp. You’ll need to cover these things in towels or something else that is soft. Carpet remnants are a good choice. If it gets particularly windy, that can pull a tarp against the sharp edges of your antenna mounts and tear.

Be Aware of Height

Depending on what kind of boat you have, you need to be aware of problem areas like low spots. If you have a flat tarp that’s not perfectly taut, there will be dips. If it rains, water will pool in these low spots. If it’s too heavy or in a bad spot, it can create leaks. When covering a boat for winter you need to think of snow buildup. A good countermeasure is to have a pole or something else in the center of your boat. With the tarp over this water will flow down and away. Cover the pole top with carpet remnants for safety.

Add Vent Spots

Humidity can be a problem for a tightly sealed cover. Especially if you’re storing your boat near water. You’ll need to make sure you have some vent spots to allow humidity to escape. This will prevent the formation of mold and mildew under the cover. Keep your vent spots near the base of your tarp to prevent water leaking in. If you’re worried about tearing, secure these vent spots with duct tape at the edges.

Securing Your Tarp

Many tarps for boats have grommets installed in them already. These are some of the best kinds to use. They allow you to secure your tarp with tie downs or bungee cords after they’re in place. The grommets are typically secured in a reinforced way that will prevent tearing.

Depending on where your boat is stored, you can loop your tie downs under the boat to hold the tarp in place. Another option is to anchor them to something heavy on the sides of the boat. Typically, buckets of sand will do this job well. Just make sure they can stand up to the weather.

The Bottom Line

You don’t need to spend a ton of money to cover your boat. You can get a good quality, heavy duty tarp at a good price. You just need to make sure you secure it the proper way. Avoid those low spots, watch out for problem areas like windshield frame corners. Make sure that you have the cover tightly secured. You can even hang old water bottles filled with sand or gravel from the islets if you need to. Whatever keeps the tarp weighted down and in place without causing damage.

For the few moments it will take to tarp the boat, you’ll save yourself a lot of trouble. Keeping your boat clean and safe is well worth the effort.
