On a lead line what marks the 25 fathom?

Explanation:
On a lead line, depth is read by recognizing a specific arrangement of marks rather than by reading numbers. The line is marked with long and short marks in patterns that let you identify certain depths at a glance. The point corresponding to twenty-five fathoms is represented by a distinct pattern: two longer marks with three shorter marks in between, a pattern often described as two by three. This visual cue is used because it stands out and lets you quickly confirm that you’ve paid out twenty-five fathoms without counting every individual mark. Other depth values would be indicated by different mark patterns, so the two-long, three-short arrangement is the standard sign for twenty-five fathoms.
