What should you do once the stern is clear of the dock?

Once the stern is clear of the dock, casting off the bow line is the appropriate action to take. This step is important because it facilitates safe and organized maneuvering of the vessel away from the dock. When the stern has cleared, the boat is essentially positioned to transition smoothly into open water, allowing for better control.

Casting off the bow line after the stern is free provides the necessary leverage to pivot and steer the boat out effectively without the risk of hitting the dock or other vessels. It helps to ensure that the boat is free to move forward while allowing for a safe departure.

Maintaining control of the boat is essential in this situation, as improper actions could lead to collisions or difficulties in maneuvering. Therefore, this specific sequence—first ensuring that the stern is clear and then casting off the bow line—promotes safe boating practices.
