Drain fuel and water tanks to no more than 1/4 of their capacity before shipping. Depending on the size of your boat, you will need to take steps to reduce its height and width while in transit. These include disassembling masts and in some cases removing cockpits to prepare the shipper for a boat transport.
Stow and secure all loose items aboard the boat. Disconnect the battery and close and lock all ports, hatches and windows.
If your boat is to be delivered to a launch site, check the hull thoroughly for watertightness before launch, and be sure you have all required safety equipment. Whenever possible, step the mast and fit the rigging in the landing area before the boat enters the water.
