What should you do before casting off?

Prior to casting off, it's essential to keep the boat tied to the dock while warming up the engine. This practice ensures that the engine is functioning properly and allows the operator to assess any potential issues while remaining securely moored. Warming up the engine helps to ensure better performance once the boat is in motion and is crucial for safety, as a well-functioning engine is necessary for maneuverability.

While ensuring the boat is in the water is important, it does not encompass the critical step of warming up the engine, which can directly impact the safety and readiness of the vessel. Starting the engine and immediately casting off without this warm-up could lead to engine failure or other complications on the water. Collecting payment from passengers is not directly related to the pre-departure preparations needed for safe boating activities. Therefore, maintaining the boat tied to the dock ensures both safety and preparedness for a successful outing.
