Boat Cover Protection
The sun's UV rays, over time, can prematurely age paint, graphics and other boat surfaces as well as deteriorate seating. Boat covers with high UV protection will maintain their colors, strength and longevity as well as protecting the boat from sun damage. Solution-dyed acrylic fabrics such as Sunbrella® and Outdura® are designed for the most intense sun conditions and maintain their color and strength over time while protecting what they cover. With solution-dyed marine polyester fabric, Sun-DURA®, and high-quality polyester marine fabric, Performance Poly-Guard®, you can be ensured you’ll be protecting your investment with the highest quality marine fabrics offered. Our cover UV rating is based on the longevity, steadfastness and weave density that the cover will provide when exposed to the sun. We recommend choosing a lighter color in the most intense sun conditions to keep your boat cooler.
The only type of rain to be concerned about is "acid rain" which doesn’t occur that often now due to more stringent regulations by the EPA. Industrial burning of coal and other fossil fuels released waste gases containing sulfur and nitrogen oxides into the air - and when they mixed with water vapor in the atmosphere they formed acids. Dirt can have an impact on the water repellency of a cover, so periodic washing can help. NEVER use a waterproof cover/fabric on a boat because any moisture trapped under the cover/fabric will likely cause damage to the interior of the boat. Water repellency will repel the majority of water/rain, however it is possible that moisture can penetrate the covers during heavy rainfall and/or if water or snow is left to "pool" on a cover. Using support poles underneath a boat cover can help tremendously to prevent damage and leakage.
It's easier to prevent mildew than it is to eliminate once embedded in the fibers. Covers with higher breathability will greatly help the resistance of mold/mildew as moisture won’t get trapped and can escape freely. Synthetic canvas fabrics do not support the growth of mildew. Mildew around water can always occur, but a quality boat covers with proper drying techniques will go a long way to keeping your boat cover looking it’s best.
Strength of a boat cover fabric is important and is rated based on the tensile; breaking strength and elongation of textile fabrics. The fabrics with the highest tear strength (such as Performance Poly-Guard®) will resist further tearing even when punctured or accidently torn.
By breathability we mean a fabric’s ability to allow condensation under a cover to easily evaporate. This is critical because moisture trapped under a boat cover has nowhere else to go and will promote the growth of mold and mildew causing damage to your boat seats, flooring and instrumentation. Don’t be fooled into a waterproof boat cover. Moisture can penetrate a cover during a heavy rainstorm (remember rain water won’t hurt a boat finish), heavy dew or melting snow. However, boat cover fabrics with the highest breathability ratings will ensure that the moisture will easily evaporate. Rain isn’t your boats worst enemy – sun, bird droppings or tree sap do the most damage! Because our fabrics are breathable, they dry fairly quickly once the storm has passed.
Boat covers are taking the abuse that nature and elements would put onto your boat, but they don't last forever. We offer a variety of fabrics with different limited warranties to fit your budget and protection needs. Under normal use you should comfortably be able to get the stated warranty out of your cover. However, that doesn't mean Carver by Covercraft won't last even longer than the warranty period as we have customers that come back well over a decade later when treated with care. A boat cover is a small investment to protect your boat and your re-sale value.
