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 Staffordshire and Worcestershire Canal was opened in 1772, engineered by James Brindley. It cost a little over £100,000 at the time. It links the River Severn at Stourport to the Trent and Mersey Canal at Great Haywood Junction in Staffordshire. There are 43 locks (45 if you don't fancy the deep wide locks at Stourport) and the canal is 46 miles in length.
