Winding hole


A winding hole is a widened area of a canal, used for turning a canal boat such as a narrowboat.

Etymology

The word is commonly believed to derive from the practice of using the wind to assist with the turn.
Another Etymology, however, is the Old English word for turn - "Windan",. Old English was in use up to and including the 18th century when the canals where built. Much UK canal terminology comes from spoken rather than written tradition and from bargees who did not read or write.
It is also possible that the word has a similar derivation to that of the windlass, which derives from the Old Norse "vinda" and "ás"—words currently used in Iceland—where the modern word for "windlass" is "vinda".

History

Because the average width of a canal channel is less than the length of a full-size narrow boat it is not usually possible to turn a boat in the canal. Winding holes are typically indentations in the off-side of the canal, allowing sufficient space to turn the boat.

Use

A winding hole consists of a "notch" in the canal bank. A turning boat inserts its bow into the notch and swings the stern round. In the days of horse-drawn boats, this was accomplished using bargepoles.
