What is the primary purpose of a Safe Water Mark?

The primary purpose of a Safe Water Mark is to serve as a navigational guide. Safe Water Marks are used to signify that there are navigable waters ahead and that it is safe to proceed. These markers are typically displayed in a way that indicates unobstructed water, allowing vessels to navigate safely through areas such as channels or fairways.

They provide key information to mariners, signaling that they are in open waters without any immediate hazards, which can be critical for safe navigation. The mark is often red and white striped, making it easily recognizable.

While other types of markers do indicate hazards, anchorage, or specific dangers, a Safe Water Mark specifically indicates that the waterway ahead is clear for navigation, which is its main feature.
