Now I know why they call them "barge" boats just barge your way through!

Strictly speaking Narrow boats. Being in a 72 foot steel boat in a narrow lock with a couple of sweating plastic boat owners needs a calm head, but other narrow boats can take the knocks. 4mph max, a canal you can generally stand up in and loads of pubs, it has its attractions.

I thought you were talking about cruising cats.
