Tjalk sounds familiar. I think she was at the last Folksail at Yorkshire Waterways Museum. Chris's keel was Southcliffe, also Sheffield-size, still with her JP2 in, but he has the survey boat Ouse Patrol now. Until recently he was lockkeeper at Cromwell and we've just found out he is 'Lockkeeper of the Year' for CRT.

And much busier waterways I should imagine. It's absolutely criminal how underused our waterways are!
