Support your boat cover with a pole or PVC frame.

If your boat cover is not properly supported, it can sag in the middle after a heavy rain. You don’t want rain, leaves, dirt, and other debris to collect on your boat cover, since they can promote the growth of mold and mildew.

You have two options for a boat cover support: buy a boat cover support system or build your own.

TinBoats.net offers instructions on how to build a PVC boat cover frame. Building your own frame means you can customize the frame to fit your boat perfectly.

As long as you have the time and energy, building your own support frame is one of your best options for a sturdy, customized frame.

Here is what you’ll need to build your own boat cover support:

Materials:

• 3/4″ or 1″ PVC (available at most hardware stores)
• 3/4″ or 1″ PVC elbows, couplings, and tee’s (how many you need depends on the size of your boat)
• PVC glue
• Garden hose (to help form the arches)

Tools:

• Hacksaw
• Measuring tape

"The outside of the fabric was wet to the touch but the inside remained impenetrable to the moisture and the boat remained bone dry!"

Need a boat cover for the winter? Check out these customer reviews for the DuraShield Trailerable Fishing Boat Cover below.

“With the price being so low and free shipping, I had little expectations of this product. Shortly after it arrived we were hit with a very early snow storm and 8 inches of heavy wet snow came down on it. I held my breath after each passing hour of the storm, fearing this first test would be the cover’s last.

I woke the next morning to find that it had sagged a little bit from the weight of the snow but there were no tears in the cover or in the straps that are nicely stitched into it! I actually had to use a plastic shovel to remove the majority of the snow and then broomed off the rest. The outside of the fabric was wet to the touch but the inside remained impenetrable to the moisture and the boat remained bone dry! I was amazed!

My boat is a 16ft V-haul and even with my outboard still mounted on the transom, the cover accommodates the entire area including the motor with ease! I can’t say enough about my satisfaction of the quality of this product and how simple and quick it was to order it and receive it!”
- Sargeant V.

“Bought this to cover my Sunfish sailboat for winter storage. Not an exact fit, but plenty of loops to accommodate bungees and cords. No problem during short trailering trip.”
- C. L. S.

“Good product. Used on 15′ Old Town canoe with flat stern.”

Use a boat cover support system to prevent sagging.

Want to get more life out of your boat cover? Treat it right with these boat cover care tips from DuraShield Covers.

Cleaning the Cover

The first step in caring for your boat cover is keeping it clean. If your boat cover is treated with special UV and weather resistant coatings, we recommend hand washing only. Clean the cover with a soft brush and lukewarm water.

If necessary, the cover may be machine washed in COLD water with NO SOAP; however, machine washing is harder on the fabric. Do not use soap or detergent, as these may remove the protective coatings added by the factory and/or void the manufacturer’s warranty. Line dry the cover if possible, or machine dry on the delicate or air only setting.

Storing the Cover

When it’s time to put your boat cover away for awhile, make sure it is clean and fully dry before storage. Brush off dirt and debris, wash the cover, and allow it to dry completely before folding or rolling the cover for storage. A mesh storage bag will keep your cover neatly folded while allowing it to breathe.

Boat Cover Support

To prevent the boat cover from sagging, we recommend using a boat cover support system. If the cover is unsupported, water can pool in the middle, which creates the perfect breeding grounds for mold and mildew.

A strap system, support pole, or support structure (such as a PVC frame) will allow rainwater to run off the cover without pooling. You can either buy a ready-made boat cover support system, or you can custom-build your own for a boat-specific fit.

Unlike cotton material, polyester boat covers do not support the growth of mildew.

Synthetic boat covers do not support the growth of mildew; however, any dirt, pollen, or grime that is allowed to build up on the cover creates a prime environment for mold and mildew. That’s why no matter how mildew-proof your boat cover is, you still need to keep it clean in order for the cover to do its job.

What Makes a Boat Cover Moldy?

Mold and mildew thrive under certain conditions: 1) something to feed on (dirt, pollen, leaves, etc.), 2) the right temperature range, 3) moisture, 4) darkness, and 5) no air flow. The more factors you can eliminate, the less likely you will have problems with mold and mildew.

Mildew-Resistant Boat Covers

A boat cover that resists mold and mildew will be synthetic (think polyester instead of cotton), water-resistant, and well vented. The right venting design allows moisture and condensation to evaporate and air to flow underneath the cover while keeping rain water out of the boat.

Mold and Mildew Prevention

Preventing the growth of mildew is easier than getting rid of it. One way to prevent mildew is to make sure the interior of your boat is clean and dry before installing the boat cover. Remove life jackets and removable seat cushions and let them dry in the sun. Any sun lotion, pollen, crumbs, or dirt left in the boat will attract mold, so clean the boat thoroughly. Then let it dry in the sun. Remove any trace of moisture or condensation before covering the boat.

Another prevention tip is to place packs of silica gel (or other moisture-absorbing packs) underneath the boat cover. The silica gel should absorb any moisture that forms inside the boat.

"Better than the more expensive one we purchased..." - Sarah G.

“My husband said he likes this boat cover and that it is good quality. He said it was better than the more expensive one we purchased at Walmart a few years back that finally fell apart. I like that the color is neutral enough that I haven’t even noticed that ol’ boat with its new cover.”
- Sarah G.

“For what this costs, it’s working great as a winter cover. It stays waterproof (it rains sometimes here in the northwest), keeps crud out (the boat is parked under a tree), and breathes enough not to mold.”
- NWGuy (Seattle, WA)

“Love the product and cannot beat the price. It fits my Gheenoe almost perfect when otherwise I would have had to special order one. Thanks so much!!”

Secure your pontoon cover tightly for trailering.

If you want to protect the value of your pontoon boat and keep it looking good for years to come, we recommend investing in a pontoon boat cover to prevent weather damage and dirt buildup.

Getting a Secure Fit

In order to get the most secure fit for your pontoon cover, find a cover that fits your boat as closely as possible. You don’t need to spend hundreds on a custom cover, but the fit should be close enough to prevent excessive sagging or wind lofting. Universal pontoon covers are usually available in more than one size. Choose the size that most closely fits the dimensions of your pontoon.

Securing the Cover for Trailering

Once your cover is on the pontoon, secure it with the straps provided. Add extra tie downs if needed. Tying down the cover is especially important if you will be trailering your boat. Don’t allow the cover to flap in the wind. This causes excessive wear and tear on the cover, and it could even cause the cover to come loose and fly off during travel. The tie downs for trailering should be secure, and there should be enough tie downs to keep the cover tightly in place.

Securing the Cover for Storage

Even if you are just storing your pontoon and not trailering, the tie downs should still be secure in case of heavy rain or strong wind gusts. Because of the large deck space on a pontoon, sagging is likely to occur without support poles to hold the cover in place. Most likely you will need more than one support pole to prevent sagging.

Getting the right size boat cover is important for a secure fit.

Finding the right size boat cover is important for a secure fit. Our trailerable boat covers come with an elastic hem that fits snugly underneath the boat deck. There are no snaps or metal parts that could mar the boat’s finish.

Measuring Your Boat

Use a measuring tape to get the right dimensions for your boat and find the right size boat cover.

To find the centerline length, measure the distance from bow to stern in a horizontal line. Do not measure up and over windshields or other objects.

To find the beam width, measure the distance from side to side at the widest part of the boat. Include the rub rail in your measurement.

Getting the Right Fit

If your boat has rails taller than 6 inches or a trolling motor that you want covered, add a foot to the centerline length. If you have a platform, swim deck, or other extension on your boat that you want covered, add their length to the centerline dimension.

Universal boat covers are made to fit boats within a certain length range. Although you might not get a perfect fit, the elastic hem and tie down straps will secure the cover to the boat and keep it from flapping wildly in the wind.

How to measure for a boat cover

You can prolong the life of your boat cover with proper care and maintenance.

With proper care and maintenance, you can make your boat cover last longer. The better you take care of your boat cover, the better it will protect your boat. Here are some tips on caring for your boat cover.

Rain and Moisture

Don’t let water stand on the boat cover. Pools of standing water create a ripe environment for mold and mildew, which eats away at the cover material. Use a boat cover support system that allows the water to run off the cover, rather than collecting in pockets. The dirt in water and melted snow soils the cover and prevents it from protecting your boat as it was meant to do. The special coatings on your cover are designed to work best when the cover is clean and free of dirt and debris.

Snow

Don’t let snow build up on the cover. The weight of heavy snow on top of the cover can tear the material, and when it melts, it creates a pool of standing water, which creates more problems. Use a garage broom to brush snow off your boat cover after each snowfall.

Tie Downs

Make sure the boat cover is tied down securely, both for trailering and for outdoor storage. If the cover is too loose, the wind will loft the cover and whip it around, which can damage the cover and possibly your boat as well.

Padding

Add extra padding to any edges or wear spots on the boat, such as the windshield. If the cover is allowed to chafe against these abrasion points, the material will wear down quickly and eventually result in holes in your cover.

Cleaning

Clean the boat cover often to remove dirt, debris, salt, pollen, and other contaminants that could support the growth of mildew. Use a soft brush to remove loose dirt and debris. Wash the cover with lukewarm water. Do not use soap or detergent to clean the cover, as it could remove the protective coatings that repel water and UV rays.

Storage

Allow the boat cover to dry thoroughly before folding or rolling the cover for storage. A wet boat cover encourages the growth of mold and mildew.

- J. Carlisle

“I installed it right after it arrived, fit like a glove. Thank you.”

“Very good quality. Easy to cover the boat. Many tie downs for security. This should last many years!”
- C. Deignan

"Good cover for the price." - Spencer

Pontoon Cover Reviews

“Good cover for the price. This cover fit over my Playcraft 26 foot pontoon boat just fine including the bimini top when it was folded down. The front of my boat is kind of V shaped and the cover is straight on the end like a rectangle shape but it still worked. The tie downs hold the cover down well when the boat is on the trailer but I don’t think it can be used with the boat on the water without a lot of hassle. I looked at custom covers with price over $1000 and plenty of others off the shelf in the $300-500 range so this cover is pretty good for the price.”
- Spencer

“Great cover for the money. We purchased this cover for our Tracker Fishin’ Barge. Since it’s generic the fit isn’t great but we’ve found ways to make it work. Tracker doesn’t seem to think covers are a good money maker. That’s a whole other story. Don’t get me started! Too bad DuraShield doesn’t make boats.”
- T. Gordon “Flash”

This universal boat cover offers protection from rain, moisture, UV rays, and mildew.

Choosing a marine boat cover doesn’t have to be complicated. Just follow these three easy steps to find the right size and cover type for your boat.

1. Decide on the type of boat cover you need.

First, you need to decide between a trailerable, storage, or mooring cover. Each is designed specifically for the function it will perform.

Next, you need to decide what type of fit you want: universal, semi-custom, and custom. Universal, the most cost-effective choice, fits a range of boat sizes. Semi-custom fits specific boat types and sizes and gives a more custom fit for a slightly higher price tag. Custom is designed for your specific boat and accessories for a fit that’s just right, but it will cost you more than a universal or semi-custom boat cover.

Finally, you need to decide on the level of protection you want. Boat covers are available in different levels of breathability, thickness, UV protection, water resistance, mildew resistance, and other features.

2. Measure your boat.

Measure the boat’s centerline from bow to stern. Do not measure up and over the windshield. Instead, measure in a straight line.

Keep in mind that factors like swim decks, platforms, and other accessories that you want covered will affect the required length of the boat cover. If you want these accessories covered, measure your boat from the bow to the furthest point that extends out from the stern.

Next, measure the beam width at the widest point of the boat.



3. Use the boat measurements to help you find the right cover.

Even if the boat cover description states that it is designed to fit your boat type, always check the boat measurements against the cover measurements to ensure a proper fit.

Check the boat cover sizing chart, if provided, or check the boat cover description to find the length of the boat cover. Then check the max beam width to make sure the cover is wide enough to protect your boat.

Look for notes on sizing, such as “not for cabin/console boats” or “not for extra tall windshields,” that may apply to your boat.

Once you receive your boat cover, try it out on your boat to make sure it fits, and keep the purchase receipt and warranty information in case anything goes wrong in the future.
