Yes. Boat fender covers are designed to reduce rubbing, scuffing, and black marks between your fenders and your boat’s hull. A high-quality knitted acrylic or polyester fender cover acts as a protective barrier, helping to prevent gelcoat scratches, streaking, and wear—especially in marinas, locks, or when rafting up alongside other boats.

The best boat fender covers are typically made from UV-resistant loop-knit acrylic or marine-grade polyester. These materials are durable, soft, quick-drying, and resistant to saltwater, mildew, and fading. Loop-knit acrylic is widely regarded as the premium option because it offers superior stretch, breathability, and long-term protection.

Your fender cover size should match your boat fender size. For example, if you have a 21” x 8” fender, you need a cover designed specifically for that size. Always check both diameter and length to ensure a snug, secure fit that won’t slip off during use.
