Fascinating film, many thanks for sharing.
I’ve often wondered what it was like up there. It looked a bit narrow and weedy towards the end! Wonder what the depth of water is? I believe hire craft could go up there at some time in the past but have an idea the limit of navigation was Tonnage Bridge??
I’ve always wanted to have a look up Waxham Cut and Catfield Dyke as well, that would probably be a canoe or small boat job too.
