When everything’s packed and ready to go, double-check that you have your Switch key tether. Also, take a quick look at your trailer tires to ensure they’re properly inflated, and check that your trailer is properly coupled to your tow vehicle. It's best to have a second person on hand to ensure the trailer lights are functioning correctly. Your next stop should be to top up with fuel if you haven't already, and don’t forget to top off those coolers with ice.
Arriving at the boat launch: Upon arriving at the launchpad, some regions may require you to wash down your Switch before putting it in the water. Double-check those regulations and pull off for a quick rinse if needed to ensure you're not giving any aquatic invasive species a free ride into a new body of water.
Next, pull off to the side, check that your drain plug is properly installed and load anything from your vehicle onto your Switch. Remove any covers, tie-down straps, and position your docking fenders if you have them. Attach the docking lines to the cleats so they’re ready to go, and connect a lead line (usually a long rope) to the rear of the Switch so you can pull it free from the trailer.
