If your boat isn't equipped with a pylon or ski eye and you enjoy watersports activities you need a tow harness. It creates a tow attachment point at the center of your boat behind your outboard or stern drive. This tow harness is perfect for pulling a skier wake boarder knee boarder or one-rider tubes. Simply clip it onto your boat with the hooks provided and attach your ski or tube rope. A 6" float keeps the attachment loop floating on top away from your propeller. It measures 12-feet long to fit larger boats and pontoons and features a snap hook opening measuring 7/16".
