At which mark is a white rag indicated on the lead line?

A white rag on the lead line is a visual indicator used in maritime operations to signify a specific depth of water. When working with a lead line, various marks are placed along the line to denote different depths. The white rag is traditionally employed to represent a depth of 15 fathoms.

This particular marking helps mariners quickly assess water depth while navigating and ensures safety and precision in operations, especially in unfamiliar or potentially hazardous waters. The choice of 15 fathoms as the standard for the white rag provides a clear reference point that can be easily recognized and communicated among crew members.

By understanding the significance of the white rag and its corresponding mark, boat crews can make informed decisions about their navigation and adjust their operations based on the depth being indicated.
