The Polyform CM Series Mooring Buoy is built for genuine strength, durability, and boat protection, giving real added security to any mooring. This 17-inch version comes with galvanized iron and a protective vinyl-coated eye, in white with a blue stripe.
Both mooring iron options, galvanized or stainless, share a 1/2-inch central rod, a large 4-3/8-inch eye, and a 1-1/2-inch swivel to keep things strong and secure under load. The CM Series has held up as a proven mooring buoy design over the years, and boaters worldwide keep coming back to it.
A soft vinyl surface won’t harm your boat’s finish, Polyform’s unique vinyl valve seals securely, and even wall thickness throughout gives it real strength and durability. One-piece design.
