Choosing A Boat Cover: Key Considerations

Boat covers are essential for protecting your vessel from the elements, such as UV rays, hail storms, dust, bird droppings, and other environmental factors. When choosing a boat cover, the most important factors to consider are fit, weather protection, style, and budget. A good boat cover should be waterproof, UV-resistant, and mildew-resistant, with a snug fit to ensure maximum protection for your boat. It is also important to consider the type of fabric, fastening system, and whether you need a trailerable or non-trailerable cover.

Fit

The fit of a boat cover is the most important factor when choosing one. It doesn't matter what the cover is made of or what it looks like if it doesn't fit properly. A cover that is too small will leave parts of the boat exposed to the elements, while a cover that is too big will allow water to pool on its surface and wind to get underneath, potentially causing damage. Therefore, it is crucial to take accurate measurements of your boat to ensure a proper fit.

To measure the length of your boat, start from the tip of the bow and measure to the centre of the stern. Include any aftermarket extensions, such as bow pulpits or swim platforms, in your measurement. Always measure in a straight line, rather than up and over windshields or rails.

To determine the width, measure the widest point of your boat, excluding bumpers or other removable items. Again, measure in a straight line, and ensure that any parts that will be removed before covering are not included in your measurement.

When purchasing a boat cover, you will also need to decide between a trailerable cover and a non-trailerable storage cover. Trailerable covers are designed for boats that are transported on trailers and typically feature durable tie-down strap systems. On the other hand, storage covers are meant for boats that are stored at anchor, at the dock, or on a trailer and usually have rope tie-downs.

Before installing a boat cover, it is important to examine the boat for any sharp points that could puncture the cover. Cover these points with extra cloth or foam pads. Start by securing the end of the cover with a "front" label, stretching the rest towards the rear and over the sides of the boat, ensuring it is centred and even. Then, locate and separate all the tie-down straps or ropes, following the instructions provided with your boat cover for proper securing.

A snug fit is crucial for a boat cover to function effectively. Sagging areas can collect standing water and snow, shortening the lifespan of the cover. Therefore, it is recommended to use heavy-duty tie-down straps when trailering. Additionally, when removing the cover, fold it towards the centre from both sides and roll it from back to front to facilitate the reinstallation process.

Durability

Boat covers can vary in durability, with some lasting only a year or two, while others can last up to a decade or more. The durability of a boat cover depends on several factors, including the quality of the materials used, the type of fabric, the fit, and the environment it is used in.

Firstly, the quality of the materials is crucial. High-quality, coated synthetic fabrics tend to be more durable than natural yarns. For example, pigment-dyed polyester fabrics have a good strength-to-weight ratio and are an excellent choice due to their breathability, water resistance, and UV protection. Acrylic-coated polyester, such as Hot Shot™, is another durable and affordable option that is breathable, stain-resistant, and can withstand mildew and UV rays. Urethane-coated, solution-dyed polyester fabrics and solution-dyed acrylics are also known for their durability.

The type of fabric and its properties also play a significant role in durability. The fabric should be breathable and water-repellent, with the ability to withstand UV rays and mildew. This combination of breathability and water repellency is essential to keep rainwater out while allowing trapped water vapour to escape. Additionally, UV and mildew resistance will protect the boat from sun damage and prevent the growth of mildew, respectively.

The fit of the boat cover is another critical factor in its durability. A cover that is too small will leave gaps that allow water and snow inside, while a cover that is too big will allow water to pool on the surface and wind to get underneath, potentially causing damage. A snug fit is ideal, as it keeps the elements out while still allowing air circulation to prevent moisture buildup.

Lastly, the environment in which the boat is stored will impact the durability of the cover. If the boat is stored outside and exposed to direct sunlight, UV rays can cause the cover to deteriorate faster. Therefore, choosing a cover with UV-resistant fabric is essential for outdoor storage. On the other hand, if the boat is stored in a covered building, protection from dust, pests, and dirt becomes a higher priority. Understanding the specific elements your boat will be exposed to will help you select a cover that can effectively withstand those conditions.

In summary, when considering the durability of a boat cover, look for high-quality, coated synthetic fabrics with the right combination of breathability and water repellency. Ensure the cover has a snug fit and provides protection from the specific environmental factors your boat will be exposed to, especially UV rays if stored outdoors. By choosing a durable boat cover, you can protect your investment and prolong the lifespan of your vessel.

Weather protection

Waterproofing

Ensure that the boat cover is waterproof to prevent water from seeping into the boat. Water can damage seals, seats, interiors, and flooring, and provide an ideal environment for mould and mildew to grow. Most decent boat covers are waterproof, but it is always good to double-check.

UV Protection

If your boat will be exposed to strong sunlight, look for a cover with UV protection. The sun's UV rays can crack seals, ruin seats, and fade colours. Solution-dyed fabrics are a good option as they penetrate the individual threads, preventing fading and ensuring the cover's longevity.

Heat Reduction

If you live in an extremely hot climate, consider a boat cover with heat reduction properties. Even breathable fabrics can trap heat under the cover, so look for specially made heat reduction fabrics to manage the temperature.

Mildew Resistance

Mildew and mould can be a problem, especially in humid climates. To prevent this, choose a cover with antimicrobial properties and ensure it fits snugly without dips where water can collect. A cover that is breathable will also help prevent the build-up of moisture, which can lead to mildew and mould.

Wind Resistance

A cover that is too big can allow wind to get underneath and shift it around. Make sure the cover fits properly and has adequate tie-down straps or ropes to secure it in windy conditions.

Style

The type of cover also affects style. Trailerable covers have durable tie-down strap systems, while non-trailerable storage covers usually have rope tie-downs. Consider the frequency of use and transportation of the boat when deciding on the type of cover.

Custom-made covers are ideal as they are designed to fit your boat exactly, taking into account any custom features such as a boat grill or a slide. They offer better protection and tend to last longer than off-the-shelf models. Custom covers also allow for reinforcement in specific areas that may receive extra wear due to the boat's configuration.

When choosing a custom boat cover maker, look for a company with experience, expertise, and high-quality materials. Enquire about the fabrics used, their durability, and their ability to withstand extreme weather conditions. Hand-stitched craftsmanship is another indicator of quality.

Additionally, consider the specific features you may require, such as vents, gas flaps, or engine covers. Ensure that the cover provides adequate protection from the elements, including UV rays, heat, humidity, thunderstorms, and freezing temperatures.

Budget

The cheapest way to cover a boat is with a polyethylene tarp. The common blue tarp is the least expensive and the least durable. More durable brown or silver tarps cost more. A silver tarp’s reflectivity keeps temperatures lower in hot climates. Tarps are not ideal for moving boats long distances.

If you are on a budget, you can consider a semi-custom cover. These are designed to fit several makes and models of boats with the same hull style. They are more forgiving in terms of size variations. However, if you own a one-of-a-kind boat or your boat has a lot of unusual options, you may need to opt for a custom cover, which will be the most costly.

When choosing a boat cover, it is important to consider the type of fabric. Boat cover fabrics need to balance breathability and water repellency. They should also be UV- and mildew-resistant, with good tensile strength and abrasion resistance, especially for trailer covers. Coated synthetic fabrics are a good compromise, although they are not perfect. Cotton and polyester blends are cheaper but won't last as long as synthetic fabrics. Pigment-dyed polyester is a good choice as it is strong, breathable, and water-repellent, while also being UV-resistant. Hot Shot™, an acrylic-coated polyester, is another economical choice.

If you are looking for a budget option, the MSC Heavy Duty 600D Marine Grade Polyester Canvas Trailerable Waterproof Boat Cover is a good choice. It comes in multiple sizes and colours, with adjustable straps for a perfect fit. Despite being bargain-priced, it includes features such as an elastic cord sewn into the bottom hem, trimmable quick-snap straps, and reinforced seams.

Another budget option is the MekUk Waterproof Boat Cover, which is ideal for inflatable boats. It is remarkably inexpensive and does a good job of protecting against water and sun damage.

Finally, if you are looking for a cover for a Bass Pro Shops boat, the Bass Pro Shops Exact Fit Custom Boat Covers are designed to fit certain Nitro or Tracker models. They are easy to put on and adjust, and are remarkably affordable for a "custom" cover.
