“Mama Bob” float incorporating a universal attachment system to fit a wider variety of mast configurations. This is a shaft mounting system originally conceived for the Hobie 21 Sport Cruiser. Can attach to any mast. Helps to prevent turtling, displaces 59 pounds of water to help keep the mast from going full turtle (mast straight down). The Hobie mast float will give you the time you need when preparing to right the boat without the worry of going turtle. It also helps prevent damage to your rig and sails that can be caused if the mast head contacts the bottom when capsized. This streamlined float is shaft mounted to the side of any mast and is easily removed for racing or trailering. This float is contoured and held in alignment with the mast for minimum drag while sailing. Includes shaft mount hardware and fasteners.
