Two hitches
Our boat is on a floating dock that has one finger pier shared for every two boats. We use three cleats on the boat and 4 cleats on the dock. Starboard bow cleat to main dock cleat. Port bow cleat to inner finger pier cleat and forward spring line back to midddle finger pier cleat. Port stern cleat to outer finger pier cleat and stern spring line up to middle finger pier cleat. Therefore, our port side cleats have two lines attached, each line is cleat hitched on top of each other. Also, the middle finger pier cleat is double cleated. We have been thinking of ideas for chafe protection of lines on these doubled-up cleats. If we can figure out a proper installation of a mid-ship cleat on the boat, we'll have only one cleat doubled-up.
