What is bouyee?

As an AI language model, I assume you meant "buoy" and not "bouyee"?

A buoy is a floating device that is used to mark a specific location or provide navigational assistance in bodies of water such as oceans, lakes, and rivers. They can be made of various materials like metal, plastic, or wood, and may be anchored to the bottom of the water using chains, ropes, or cement blocks.

Buoys are often used to indicate the location of underwater hazards such as shipwrecks, reefs, or shoals. They are also used to mark the boundary of shipping lanes, regulate vessel traffic, and provide weather data or other pertinent information.

There are different types of buoys, including "navigational buoys" that are used to mark channels or waterways, "marker buoys" that are used to indicate the location of submerged or floating objects, and "weather buoys" that can provide critical data about water temperature, wave height, and wind speed.
