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.
