Quick Reference

A board rigged with a line and bridle which, when towed underwater, stretches the line by reason of the outward angle at which the bridle holds it. It is used widely in fishing to spread out a net or to keep open the mouth of a trawl—though when otter boards are used on a trawl they are normally called doors. The name comes from the otter board used by salmon fishermen to tauten their line or net as they towed it along the shore, the otter being a great predator of salmon.

The principle of the otter board was also used in minesweeping devices.
