Gray is the low-key color option for the Polyform A-4 buoy, and it hides scuffs and dock grime better than white. The A-4 measures 20.5 x 27 in and is listed for boats from 50 to 60 ft. It works as a mooring or marker buoy and as a large fender.
Polyform molds the A-Series in one piece with an even wall thickness. Heavy-duty reinforced ropeholds, including the signature blue one, take the strain of mooring lines and rough water. Between two boats, it also makes a solid rafting fender.
Inflation and deflation run through Polyform’s dual vinyl valve system, so setup and off-season storage are easy. Specs include a 64.4 in circumference, 22.5 gallon volume, and 1.125 in eye diameter. See the rest of our Boat Fenders & Buoys for other A-Series sizes.
