What happens to the numbers on buoys as one approaches shore?

As one approaches shore, the numbers on buoys typically increase. This is based on the marking system used in the United States, where navigational aids are often marked with numbers that indicate their position relative to a system of channels and waterways. The numbering system is designed to help mariners understand their location, with buoys usually increasing in number as one moves towards the higher numbered regions or towards the harbor, particularly when following the lateral system.

In this system, the numbers on red buoys increase as they are encountered from seaward towards the shore, which aligns with the general flow of maritime navigation towards safety and ports. This standardized system helps ensure safe navigation by providing reliable reference points for mariners, enabling them to assess their position relative to key navigational aids as they approach the shore.
