Well, the Lindy Line is a dance step! Somebody has a sense of humor! LINDY: Line dance move, 8-count series pf side shuffles and rock steps EXAMPLE: 1&2 Side step right & step left beside right, side step right 3-4 Rock step left slightly behind right, recover weight to right 5&6 Side step left & step right beside left, side step left 7-8 Rock step right slightly behind left, recover weight to left http://homepages.apci.net/~drdeyne/glossary.htm Composite lines are a bit more legit: they are a combination of great circles and parallels. Here is an example: If you were to sail a great-circle course from Seattle Washington to Yokohama the course would cross the Aleutian islands, so the procedure would be to sail the great-circle to a maximum safe latitude, sail directly West until you meet the great-circle again, and then continue following the great-circle to the great-circle destination point off the coast of Japan. This procedure is known as composite sailing.
