That's one of the beauties of cruising the Norfolk Broads, you don't have to mess around with locks. There are a couple of quite low bridges, with large boats at both Wroxham and Potter Heigham those two there is a pilot available to get you under the bridge. My boat I had was 21ft and it would just go under both of them at high tide. I really do miss the boat at times. It was a great pick me up if I ever felt a bit down. Also the fishing up there I really loved that.
