The term used when a vessel runs aground in an area where groundings are so common that the insurer of the ship considers it should not be deemed stranding. In most hull insurance policies, there appears the “Customary Grounding Clause” whereby it is stipulated that grounding in the Suez Canal, Panama Canal and other specified places shall not be deemed a stranding so that underwriters do not pay the cost of sighting the bottom for damage. Also deliberate contact by a ship with the bottom while she is moored or anchored as a result of the water level dropping.
