A special anchorage area serves which purpose?

A special anchorage area is designated for vessels that require a safe and secure location to anchor, particularly in inland waterways. These areas are typically established to facilitate safe mooring without impacting the navigation and commercial traffic in more heavily traveled waterways.

The designation of such areas as "Inland Only" underscores the intention for these spaces to be used in designated inland regions, away from the complexities and potential hazards associated with open sea navigation. This classification helps to clarify the specific environments in which vessel operators can use these anchorages effectively.

In contrast, the other options refer to broader categories that do not specifically align with the intent of a special anchorage area. While vessels at sea may require locations for anchoring, this does not pertain to the limitations imposed on inland waterway anchorages. Similarly, the focus on fishing vessels and recreational crafts does not capture the wider applicability of inland anchorage areas for all types of vessels requiring refuge from severe conditions or a safe place to remain when not in active operation.
