The gravity or pressure is somewhat an anchor supporting the buoy floating in the water. Furthermore, a mooring buoy has chains and loops connected to its top, which float on the water.  Such chains are settled in order for boats and ships can be moored efficiently.

Generally, using mooring buoys work in a way that such kind of buoy is buoyant while the vessels are docked or fasten securely to a very firm or support even without the need of anchor system of halting a vessel. In the other parts around the globe, mooring buoys are also taken advantaged to anchor or dock ships and boats away from the portions where coral reefs develop.

Moreover, ships or vessels employ a mooring buoy to guard coral reefs. Oil tankers use a mooring buoy since this type of buoy is easy and stable when speaking about unloading cargo or goods inside the ship. Due to its functionality in nature, a mooring buoy is mostly settled upon to the usual types of anchors nowadays.
