Most boats are exposed to daily changes in humidity and temperature from bright sunlight to cold, damp nights. These daily cycles cause expansion and contraction that take a massive toll on your boat. Aside from that, bird droppings, rodents, dirt, pollution and salt air tend to increase the damage.
One of your essential considerations when buying a boat cover is its fabric. Typically, polyester is considered the superior material for boat covers. However, the material isn’t the only thing you have to check out. Other than the material, here are some other fabric factors that should influence your choice.
Fabric weight of boat covers is included in the specifications and measured in ounces per square yard. Covers that will be in frequent use should be heavier. Light fabric covers might be easy to stow, but last for shorter periods compared to heavier weights. The ideal weight for durable boat covers is above 8.5 ounces.
If you opt for brightly colored fabrics, you want to ensure they do not fade. Look for solution-dyed instead of pigment-dyed fabrics. These fabrics are dyed before weaving them into boat covers. The color, therefore, penetrates every inch of the material, making it resistant to UV degradation and fading.
Waterproof fabrics repel water regardless of their age and are typically laminated, vinyl-coated or vinyl. Water-resistant fabrics, on the other hand, do not repel water, but are instead treated to keep water from seeping through. They can, however, leak if water pools on their surface. Regardless of your choice, ventilation is essential. Ensure your cover has built-in vents to prevent mildew growth.
The best boat covers are hand-sewn covers. Glued covers break down and fray with prolonged exposure to the sun. Topstitching is the preferred stitching method for boat covers as water effortlessly glides over the seams and not into them as is common in French stitching.
Take note of these factors when selecting your boat cover. It may seem like a trivial thing, but putting more thought into your decision will go a long way in preserving your boat.
