leadsman
RareTechnical, Historical, Nautical
Definition
Meaning
A sailor who measures the depth of water using a sounding lead.
Primarily, a specialist crew member responsible for taking depth soundings to ensure safe navigation in shallow or unknown waters. The role historically required skill in casting a weighted line and interpreting the results.
Linguistics
Semantic Notes
The term is compound from 'lead' (the metal weight) + 'man'. It is almost exclusively used in maritime contexts, particularly historical or traditional sailing contexts. It is not to be confused with 'leader' or someone who leads.
Dialectal Variation
British vs American Usage
Differences

Connotations
Evokes traditional seamanship, historical sailing vessels, and pre-electronic navigation.
Frequency
Extremely low frequency in modern usage for both. Might appear more often in British historical naval literature due to the UK's strong maritime history.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'лидер' (leader). The word is unrelated to leadership. A direct, descriptive translation like 'лотман' (from 'лот' - sounding lead) or 'моряк, измеряющий глубину' would be more accurate.
Common Mistakes
- Confusing it with 'led' (past tense of lead). Misspelling as 'ledsman'. Using it to mean a person in charge.

Frequently Asked Questions
No. A coxswain steers a small boat, a helmsman steers the ship. A leadsman's sole duty was measuring depth.
No. The role has been completely replaced by electronic depth sounders (echosounders) and sonar.
It derives from the metal 'lead' (/lɛd/), not the verb 'to lead' (/liːd/).
Primarily in historical novels about the sea, maritime museums, or in discussions of traditional sailing techniques.
