Gravity buoy

Abstract

The gravity buoy includes a can float that is visible above the waterline and provides the buoyancy for the device. A pulley assembly permits a tether under constant tension to pass easily through a point near the bottom of the can float, thus creating a pull point. A tension weight provides the downward force that puts the tether under constant tension so that the can float maintains its location above the anchor, and helps keep the can float vertical in the water along with concrete ballast inside the bottom of the can float. An anchor provides the downward force that will keep the buoyancy of the can buoy and the weight of the tension weight from displacing the gravity buoy from its intended location. An inline weight provides downward force on the anchor-side of the tether.
