When mooring the ship-- #1 line goes forward of the ship to the pier, #2 & #3 are crisscrossed to the pier, #4 & #5 are crisscrossed to the pier and #6 extends aft of the ship to the pier. Here is how it works. If the ship tries to move aft-- lines #1, #3 & #5 hold the ship in place. And if the ship moves forward then lines extending aft, such as #2, #4, & #6 hold the ship. A “bight” is a line looped back. This process is called “doubling up or tripling up all lines” They simply send the extra line on the deck back out to the pier, put it around the bollard on the pier and back to the ship—using a bight produces a triple up of line effect. We used this method on the LST-325 when we moored to the pier in New Orleans during the 2003 river cruise. There was a lot of wave action from passing ships from both directions in the river, wind, current, etc…
