Ferrous has been through twice in the last few years, I think once pre pandemic and once since from South to North can't remember exact dates but from memory both times gauged at the south portal on the evening before. When I took Ferrous 2022 I wanted to go from North to South, we could get around the first 1/3 of the boat through where the cabin is higher and thinner but towards the middle where the cabin spreads is where the radius of the gauge was catching. They were in two minds about going through knowing the history of the boat going through multiple times with no issues but I could see the skipper of the support boat wasn't happy and didn't really want to push it on that occasion. There was a lot of talk about water levels being high but to be honest in my experience of the Wolverhampton Level it wasn't particularly high. Gauging Rivets to go through can be quite tight!
