What is the first action to take after getting a boat on the trailer?

The most appropriate first action after getting a boat on the trailer is to secure the boat. Securing the boat ensures that it remains stable and safe during transport. This includes using safety straps or tie-downs to prevent any movement or shifting of the boat while being towed, which can help prevent damage to the boat itself and enhance safety on the road.

Once the boat is secured, the other actions like inspecting the boat, turning off the engine, or getting out of the way can be addressed in sequence, but securing the boat is crucial to ensure its integrity and safety right after trailer loading.
