Which definition refers to a line formed by two objects?

• A. Wreck symbol
• B. Tide station symbol
• C. Transit definition
• D. Line formed by two objects

Answer: (C)

A transit is the line you get when two fixed objects line up in your sight. Sight two landmarks and the line connecting them becomes a transit line on your chart, and your vessel lies somewhere along that line. By using a second pair of objects to form another transit, you create a second line of position; where the two lines cross pinpoints your location. Wreck symbol and tide station symbol are chart indicators, not lines of position, so they don’t describe a line formed by two objects. The term that defines a line formed by two objects is transit.
