What is the first thing you should do after retriving a boat onto a trailer?

The first thing you should do after retrieving a boat onto a trailer is to secure the boat properly by attaching the winch strap and safety chains. This ensures that the boat is stabilized and won’t shift during transport. Additionally, it's important to check that the trailer lights are functioning and that the trailer is properly connected to the towing vehicle before driving away. Finally, ensure that any drain plugs are removed to prevent water accumulation in the boat.
