A wind-ing hole (pronounced as in wind = breeze, not as wine-ding) is a wide section of the canal where narrowboats up to 70 feet (21.3 metres) in length, the maximum accommodated by most locks on the canal system, can be turned round.

The Basingstoke Canal can be found in Southern England between the village of Greywell in Hampshire and Woodham in Surrey. It was built between 1788 and 1794 and is 32 miles long with 29 locks. After many years of restoration it's now fully navigable, and connects to the River Wey Navigation, which in turn joins the River Thames Link
