All Custom Covers have sewn in reinforcements at critical wear points, such as the windshield, cleats, and various features such as the port trolling motors. Custom Covers also include tie-down straps, and rope with a patented Rope Lock in the hem for a custom fit against your hull. Both PolyCotton and Polyester fabric covers have 4-ply seams, sewn in tie-down loops, double folded hems and are Fully Trailerable! You simply cannot get a better fitting cover for your boat. Remember to properly support your cover when not trailering for years of use!
