Thank you everyone for all your advice. The photo and video were particularly helpful....i'll probably end up having a nightmare about that bend!! My partner is a very competent captain and he has taken the boat through Cardington Lock several times. The first time he didn't even touch the sides....think he was trying to impress me.....lol...he succeeded!! By the way, what happens if you do meet another boat on a really narrow bit?? Is it whose got the bigger boat? What's the usual etiquette?
Does anyone have any tips on the Ouse down to Denver and from Stanground Lock to Northampton.
