Boat owners, this pair of marine-grade buoys will make your docking so much easier and safer! Measuring 14.9 inches in diameter and 17.7 inches tall, these inflatable vinyl fenders are perfect for boats from 15 to 40 feet. The marine-grade vinyl is UV-protected and stain-resistant, so they stay looking bright and clean season after season. The 3.8mm even wall thickness provides maximum strength and durability without being too stiff. The large 1-1/8 inch line holes fit most shackles, anchor rings, and ropes easily, and the reinforced eyelets won't break under pressure. Comes with an inflator and 2 needles so you can adjust the pressure to your preference - firm for heavy waves or softer for calmer conditions. The one-piece construction prevents splitting and leaking, which is huge when you're dealing with water safety. Use them as mooring buoys to mark anchor locations, as dock bumpers to protect your hull, as fishing marker buoys, or even as swim buoys for water safety. The bright color makes them highly visible, and the soft vinyl won't leave scuff marks on your boat's finish. Seriously, having quality fenders makes such a difference in protecting your investment and making docking less stressful. Your boat (and your peace of mind) will thank you!
