Which is the first course of action to take when a vessel runs aground?

The first course of action when a vessel runs aground is to assess the situation for any immediate dangers, such as water ingress or the risk of capsizing. Next, the crew should ensure the safety of all personnel on board and communicate their status to relevant authorities. Depending on the vessel's condition, attempts to refloat it may be made using engines or by lightening the load, while monitoring environmental conditions and potential damage.
