When beaching a lifeboat under oar power, at what time should the sea anchor be tripped?

The sea anchor is a critical tool used to stabilize the lifeboat and control its approach to the beach when maneuvering in the water. Tripping the sea anchor is essential for managing the boat's speed and direction as it nears the shore.

The correct choice represents the point when the crew is preparing to execute a maneuver that involves reversing the oars, typically indicated by the command "Backwater." This command signifies that the lifeboat needs to be slowed down or brought to a stop while still maintaining control in the water. Tripping the sea anchor at this moment allows for better handling, preventing the lifeboat from drifting too quickly onto the beach or losing control due to the waves.

This approach ensures the safety of the crew and the lifeboat, allowing for a more controlled and secure landing. Prior to this command, tripping the anchor could lead to unnecessary speed or instability, while waiting until after the boat is secured would be too late to effectively manage the approach.
