This Taylor Made Buoy is 18″ in diameter, and has a Bouncy of approx. 112lbs. We really like the Taylor Made Buoys, because the fender ends are made from injection-molded plastic. This gives us a great place to drill a hole and install our swiveling eyelet, so you can connect your Kwik-Pull™ Anchor Retriever directly to the Buoy. These Taylor Made Tuff End Buoys feature the patented Tri-Valve, giving you options for inflating the Buoy. You can blow high-pressure air directly into the one-way valve, or you can use a football-style needle and pump. Note that we recommend a max inflation of 2 PSI. This buoy is recommended for 31lb. to 40lb. anchors.
