What type of non-lateral marker provides directions and distances?

The square marker is designated for providing directions and distances. It is commonly used in navigational contexts, often indicating the location of features such as marinas, fuel docks, and other points of interest. This type of marker is crucial for boaters as it assists in safe navigation by pointing out important destinations and guiding travelers on their routes.

In contrast, other types of markers serve different purposes. The crossed diamond typically conveys specific warnings, while circle markers are often used to indicate controlled areas or specific information; triangle markers are generally used for regulatory purposes. Understanding these distinctions helps boaters navigate waterways safely and effectively.
