I enjoyed my time as a volkie the other year. I was on Cranfleet lock, usually two of us but sometimes just one. Our primary role was to assist with getting boats on their way on busier weekends, especially when the local sailing club were out. We would watch for approaching craft and set the lock accordingly, we'd do the gates and paddles unless anyone or any crew wanted to do it themselves then we would stand out of the way but be around if needed. Everyone was happy to see us there, especially the single handlers as it is quite a deep lock.
