If your ship has grounded and there is no flooding, what should you do if you cannot reverse out?

In the scenario where a ship has grounded and there is no flooding but reversing out is not an option, weighing down the ship would not be a viable solution and is not a suitable course of action in this situation.

The correct approach would involve actions that promote lightering the vessel to reduce its draft and assist in refloating efforts. Attempting to lighten the load would allow the ship's hull to rise, potentially freeing it from the grounding without exacerbating the situation. This could involve removing cargo, ballast water, or other materials that contribute to weight, enabling the vessel to float free when conditions permit.

Calling for tug assistance is a conventional response if immediate refloating isn't feasible and professional help is required, but waiting for the tide to rise may not be proactive enough, especially if immediate action is necessary. Therefore, while the alternatives may seem plausible in certain contexts, lightening the load is the most effective and practical immediate response for refloating the vessel.
