So I did this also about 10 years ago as a RCI. We went from Chester to Llangollen Wales. Just the two of us. We are long time RVers. The longboat was comfortable inside like my trailer. However there was no seating outside so all the navigation was done standing.
Learning how to run it was simple. I thought my husband would be able to do all the navigation but the “driver” has to be able to see far ahead for very tight turns and passing by other boats and he has significant vision problems, doesn’t drive at home, and it was left up to me to do all the driving. He got out to do locks, walked up ahead on blind turns, there were lots of blind turns.
We stopped at pubs for the night, ate there and tied up.
We had hopes of going to the International Music Festival in Wales. The last two miles into Wales were one way only. I dreaded another longboat coming at me. I had five in line behind me. At the last minute one headed towards us, the man’s didn’t know how to back up. My DH had to jump off ours and jump on his to help in and then the skies opened up and it poured. For two days it poured. Luckily there were spots available to hook up with electricity so we had lights and heat and we could walk into town for dinner.
Returning to Chester we had to go through a long dark tunnel without knowing if a boat was coming at us. Then over an extremely high viaduct to return. Also one way at a time.
Yes it was all very slow paced. Just not as relaxing as I watched on YouTube videos. If I had been on a larger boat with outside seating and someone else driving, like on the privately owned longboats we saw it would have been more fun. Once was enough for us.
