Anchor Chain Marking
- One fathom equals 6 feet. There are 15 fathoms (90 feet) in a shot of anchor chain.
- Color zipties
- Heavy nylon webbing ties - Red 50' - White 100' - Blue 150' - White 200' - Red 250'
- Black at each intervening 25'
- Red = 1, White = 2, Blue = 3
- Long strip of solid with a short strip in the middle
- The LONG background color is the MOST SIGNIFICANT DIGIT, the SHORT color band in the middle is the LEAST SIGNIFICANT DIGIT. So a blue band on a white background would be the number 23. A blank (no color) band in the middle of a red background would be the number 10.
- The MOST SIGNIFICANT DIGIT (background color) represents the number of HUNDREDS OF FEET.
- The LEAST SIGNIFICANT DIGIT (band color) represents the number of 25 foot SEGMENTS that are out.
- 1 mark at 25', 2 marks at 50', 3 marks at 75', and 4 marks at 100'. That repeats for the next hundred feet.
