The Watford Flight is located near to the Watford Gap services on the M1 motorway. The road can be heard here and occasionally glimpsed through the trees. The whole flight is seven locks, consisting of two single locks, a staircase of four locks, and a final top lock. A ‘staircase’ is a sequence where you emerge from one lock directly into the next, whereas single locks have a pound between them.
Traffic through the flight is strictly controlled by a CRT volunteer lock-keeper, because these are single boat locks and the staircase can only accommodate boats going in the same direction. On the day we went through, there were three boats coming down, so we had to wait a while at the bottom before being allowed to enter.
Here is a video record of the ascent through the staircase.
And here is the familiar view that greets you as you emerge from the top lock. You do get a great sense of achievement when you come through. We stopped at the services on the left before heading on to moor up for lunch after the second bridge, and then the final journey back to the marina described in the previous post.
