When moored to a dockwhat should you do before casting off while you warm up the engine?

Before casting off while warming up the engine, ensure that all lines are properly secured and that the surrounding area is clear of obstacles or other vessels. Check that fenders are in place to protect the boat from the dock. Additionally, confirm that all safety equipment is accessible and functional, and communicate with any crew members about the upcoming departure. Finally, monitor the engine's gauges to ensure it is operating smoothly.
