We have been in several tunnels this week. We started with the famous Harecastle tunnel, north of Stoke on Trent. It is a 2600m tunnel and takes about 40 minutes to drive a boat through in the dark. Fortunately I am not claustrophobic.
The second is much less known. Froghall tunnel is at the end of the Caldon, one of the most beautiful canals in the UK, if a little narrow. The tunnel is just 70m long but unfortunately less than 10% of narrowboats can fit through it. Our boat was just too tall.
The third was a railway tunnel near Leek. It turned out that for Bank holiday weekend, the Churnet Valley Railway was holding a real ale festival, and we moored our boat right by one of the stations. Beer, steam trains and narrowboats all in the same place. Lucky me!
Our final canal tunnel of the week was also near Leek and was about 120m long. We moored up for the night at a lake right by the tunnel entrance. Really really beautiful
I usually find some kind of helpful life lesson in my travels each week. Perhaps something about darkness, or light at the end of the tunnel? Perhaps something about the bear who came across a hill and could not go over, under or around it, and had to go through it? Or perhaps this week I can simply be grateful for my retirement that allows me to see such wonders.
I have been walking through a couple of canal tunnels this week. Some of the most exciting and scary times on a narrowboat are travelling through tunnels. Most canal tunnels have very little space around the boat profile. This is deliberate because when the canals were designed, the boats were pulled by horses, and the horses would not go through tunnels, so the boats were “legged” through by two strong men, lying on either side of the barge roof and using their legs to “walk” along the tunnel. These days we have engines and we have to steer 50-60 foot long boats through the tunnel with often less than a foot space on either side.
There are two keys to success. Don’t be overconfident and don’t panic. Fluid mechanics give us a big advantage because the water being pushed either side of the boat as you travel through the tunnel, gives pressure to keep the boat away from the walls. But if you are overconfident and drive too fast, or if you panic and over-react to each boat movement, then before you know it, you are bouncing the boat off the walls side to side.
I wonder of there is an analogy. Here in the UK the Covid numbers have fallen right back. Deaths and hospitalisations are very low, since so many of the population are now vaccinated. Society is reopening, with shops, bars, gyms, cinemas now back or soon to be back. In a month or so we will be nearly normal. There is talk about Coronavirus treatment in pills taken at home next winter. It really feels that there is light at the end of the tunnel.
But two things could get in the way. One would be overconfidence. If we relax the rules too fast, give up on social distancing, refuse to self isolate, then it will be back. The other would be to panic. There are some horrible new variants out there, but the science is working and we can steer our way through this perilous tunnel.
Have wonderful weekend. Let me know hat you think.
