Our custom boat covers deliver maximum boat protection during trailering and storage. Constructed of heavy-duty 600-denier polyester water-resistant fabric, they're 3-1/2 times stronger than traditional canvas covers and are finished with a water- and stain-repellent fabric treatment. Double- needle seam construction using tough polyester thread and fully reinforced at all stress areas including bow, stern and windshield. Includes 600-lb.-break-strength trailering strap system with side-seam placement every 30".
