Is there light at the end of the tunnel, or is that a narrowboat coming towards you?

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.

  1. It’s always a pleasure reading your blogs Pete. Hope all well. What a lovely analogy. India is going through the second wave at the moment. Things are really bad. “Don’t be overconfident and don’t panic” is the mantra to follow. Thanks for sharing
