What action should follow after determining there are no injuries after running aground?

When a boat runs aground and it is determined that there are no injuries, the immediate and most important action to take is to stop the engine. This is crucial to prevent further damage to the boat and to ensure the safety of everyone on board. Continuing to operate the engine while the boat is aground can lead to severe mechanical issues, such as overheating the engine or causing damage to the propeller and hull.

Stopping the engine allows the boat operator to assess the situation carefully without risking further harm. Once the engine is off, a thorough evaluation of the grounding situation can be made, which may involve checking for obstructions, the depth of water, or potential methods to refloat the boat safely.

After stopping the engine, other actions like calling for assistance, checking gear, or signaling other boats may follow based on the circumstances, but the immediate priority must always be to stop the engine to protect the vessel and those on board.
