What is the first step when casting off with no wind or current?

When preparing to cast off in calm conditions, the best practice is to cast off both the bow and stern lines. This action ensures that the boat is completely free from its mooring, allowing it to move freely without obstructions. By releasing both lines simultaneously, a boater can prevent the boat from being held or pushed back into the dock, which could complicate the departure and potentially pose safety risks.

In scenarios with no wind or current, it is essential to manage the boat’s positioning relative to the dock effectively. If only one line were released, such as just the bow line, the boat might pivot or be inadvertently held in place by the remaining line. This could lead to a lack of control when starting the engine or maneuvering away from the dock, which is why casting off both lines is crucial.

The other options do not promote the safest method for casting off in those conditions. Revving the engine before checking lines can create unnecessary noise and potential confusion. Securing the boat to the dock would also contradict the action of casting off, effectively keeping the vessel moored. Therefore, releasing both lines provides the clear and controlled approach needed in calm conditions.
