Prepare your boat for launching away from the ramp as a courtesy to others and to prevent rushing during the launch.
Register your boat and pay for the launch at the self-service station.
Ensure that there has been no damage to the boat caused by the trip to the harbor.
Raise the lower unit or outboard so that it will not hit bottom during launching.
Remove trailer tie-downs and make sure that the winch is properly attached to the bow eye and locked in position.
Put the drain plug in securely.
Connect the fuel tank, check fluid levels and safety equipment.
Disconnect the trailer light plug to prevent shorting of electrical system or burning out a bulb.
Attach a line to the bow and the stern of the boat so that the boat cannot drift away after launching and it can be easily maneuvered at the courtesy float.
Visually inspect the launch ramp for hazards such as a steep drop off, slippery areas and sharp objects.
When everything has been double checked, proceed slowly to the ramp remembering that your boat is just resting on the trailer and attached only at the bow.
The ideal situation is to have one person in the boat and one observer at the water's edge to help guide the driver of the tow vehicle.
