What should you do to prepare a boat before casting off in standard weather conditions?

To prepare a boat before casting off in standard weather conditions, it is essential to cast off both the bow and stern lines. This action ensures that the boat is free to maneuver away from the dock or mooring without being restrained by any lines. By releasing both lines, you allow the vessel to steer out into open water, which is crucial for maintaining control and avoiding potential collisions or damage to the boat and surrounding structures.

In standard weather conditions, the focus is primarily on ensuring a smooth and safe departure. Having both lines released allows for easier handling of the boat as you exit the docking area, especially if wind or currents come into play. Pulling away from the dock needs to be done carefully, and securing both bow and stern lines prior to casting off provides the flexibility and range of motion needed.

The other options do not contribute positively to the preparation process. For instance, only casting off the stern line would leave the bow secured, which could lead to the boat pivoting unexpectedly, making it difficult to maneuver. Shutting off the engine isn't advisable until you're clear of the docking area, as you'll need it for controlling the boat's movement during departure. Waiting for the wind direction to change is impractical, as weather conditions can be variable and unpredictable
