Handy to Inflate: The round boat mooring buoy package includes a boat fender, inflating needle, and one hand pump. You can inflate it quickly in minutes. And it's easy to deflate, so you can store it flat when not in use, conserving your storage space. Reinforced & Large Eyelet: The 1.6"/4.1 cm eyelet is large enough to accommodate a variety of rope widths. And the material of the eyelets is also reinforced; it tested to 2000 psi tensile strength that can hold your buoy and anchor tightly. Seamless One-Piece Construction: As a 0.15 in/3.8 mm thickness buoy, it is crafted in one piece for strength and no air leakage. The drop-shaped design increases the stability of the float and high crash performance. Durable & Bright PVC Buoy: The high visibility white color makes our ocean buoy eye-catching, making it easy to notice at first glance. Made of high-quality PVC, it is UV stabilized and will not fade in the sun. Our buoy will float for multiple seasons to come. 27-inch All-Purpose Buoy: Our boat buoy ball measures 27.5"/70 cm (D) x 25.6"/65 cm (H), 1.6"/4.1 cm in eyelet diameter. Recommended for boat size: 36-39 ft/11-12 m. It's an all-purpose buoy, commonly used as a marker buoy, anchor buoy, mooring buoy, or boat fender.
