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'
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.
