Custom covers will fit down just past the rub rail.

Most fabrics used for boat covers and other marine uses are water repellent. Our fabrics, while not guaranteed 100% waterproof, usually perform well in repelling or beading of moisture. There are not any true 100% waterproof covers. This is because when the cover is sewn, the machine needle will cause a small hole in the fabric while depositing the thread. Thus, any sewn fabric would not be 100% waterproof.

The fabrics that we use for our custom covers have a water repellant coating applied by the fabric manufacturer. In some cases, a new cover may require a short period for the fabric to tighten around the thread at sewn locations. As the cover has been in use, it may require that the water repellency be renewed. We recommend that you do this once every year or two.

Yes. On the custom covers, reinforcements are placed in the most critical wear points based on your boat's pattern.

On semi-custom covers, reinforcements are placed in locations where it is most likely that there will be a wear point.

The Sunbrella® acrylic fabric is very colorfast. Covers that were made 5 to 8 years ago, made from Sunbrella® have shown very little if any color change. The polyester fabrics use a different dyeing system; while still very colorfast, they do show some change after several years of use.
