In the context of vessel handling, what would be the definition of shallow water?

The definition of shallow water in the context of vessel handling refers to a water depth of less than twice a vessel's draft. This concept is crucial for safe navigation, as the draft of a vessel is the vertical distance between the waterline and the bottom of the hull. When the water depth is less than twice that draft, it poses potential risks such as grounding or instability due to reduced buoyancy and support from the water.

By maintaining this standard, operators can ensure adequate under keel clearance, allowing the vessel to navigate safely without risking contact with the seabed or facing challenges in maneuvering. This definition aids mariners in assessing whether the navigable waters are safe for their specific vessel under various conditions, taking into account factors such as the vessel's size and the potential for changes in tide or water level.
