Actually there is a problem but it is that the average age of boaters is getting on for 60, boating has been sold for years as a peaceful, relaxing pastime, drifting along with a glass of wine and talking to the coots, the reality is usually not quite like that but by the time you can afford a boat you are likely to be retired, It can be hard work and I fear for the health and safety of some of the people I see. Poling a narrowboat off the bottom is one thing but a damn great heavy wide boat is something else.
Yes a lot of elder boaters. The majority I have met are fit and full of zest for life.
Polling a wide beam. Even at the tender age of 53 and several younger passing walkers the fat bird still sat happy as a pig in mud.
Perhaps there is an opportunity. I can see some one suggesting a canal lock zimmer frame.
Or even a panic button on each obstacle on the canal attended by Smiling angelic emergency lock keepers.
