What is the primary purpose of a buoy in relation to lines?

The primary purpose of a buoy is to aid in navigation. Buoys are strategically placed in bodies of water to indicate safe passages, hazards, and navigational routes for mariners. They serve as visual markers that help boats and ships navigate safely, providing guidance on where to steer to avoid potential dangers such as shallow waters, reefs, or obstructions.

While some buoys may interact with lines, such as those used for mooring or marking anchorage points, their core function is centered around navigation rather than organizing lines, securing them to docks, or controlling tension. This function is accomplished through various types, including lateral buoys that indicate the sides of navigable channels and cardinal buoys that provide information regarding the safest direction to navigate around underwater hazards.

Understanding the primary role of buoys in navigation is essential for effective seamanship, as it ensures safety and efficiency on the water.
