My Flashcards

Definition

Meaning

A flat, weighted board or panel, typically made of wood or metal, used in fishing trawls to spread the mouth of the net open horizontally underwater.

A specialized fishing gear component that acts like a kite or hydrofoil in water, creating lateral spreading force to maintain the net's open shape while being towed.

Linguistics

Semantic Notes

A compound noun where 'otter' refers to the hydrodynamic spreading action, not the animal. Always used in the context of fishing gear. Almost exclusively a countable noun.

British vs American Usage

Differences

No major differences in meaning. The term is used in commercial fishing industries in both regions.

Connotations

Neutral technical term in both varieties.

Translation Traps (for Russian speakers)

  • Do not translate as 'доска выдры' (board of an otter). It is a technical term: 'траловая доска', 'разноглубинный трал'.

Common Mistakes

  • Using 'otter' as an adjective modifying 'board' (e.g., 'the board of the otter').
  • Confusing it with 'outrigger' or other boat equipment.
  • Misspelling as 'other board'.

FAQ

Frequently Asked Questions

No, the name comes from the hydrodynamic 'spreading' action, which was likened to an otter's movement, not from a direct connection to the animal.

Almost exclusively in technical contexts related to commercial fishing, such as equipment manuals, fishing industry reports, or maritime engineering.

No, it is solely a noun. The action is described as 'spreading with otter boards' or 'trawling with otter boards'.

They are synonyms. 'Trawl door' is perhaps more common in modern technical usage, but 'otter board' is still widely understood in the industry.
