My hire boat has a limitation with regard to not being able to pass under Potter Heigham and Wroxham Bridges.
However, the warning does not mention Wayford bridge??? Looking at the bridge height list in the Broadcaster, Wayford is 3 inches less at 7 feet than the 7 Foot 3 inch Wroxham. How come a warning about Wayford is not mentioned? I would be devastated if I were to damage the boat.

Hi Roger,
The key difference is that Wroxham and POtter are arched and the height is for the centre of the bridge. A boat needs a much smaller air draft to get through the arch.
Wayford is flat, so provided your air draft is less than the clearance you should be OK

A little of topic, but the bridge that once caught me out was the Norwich end of Thorpe St.Andrew, having entered via the Bramerton end with room to spare, the rapidly rising tide then trapped me in, and caused a slight scrape on a roof vent, as i tried to exit with what looed like 3ins to spare on the bridge height gauge.

There's a wooden board ont he upstream side across the width of the bridge. Stops you going through when you won't fit.

Hi Roger,
Here's a photo of the warning board on the upstream side of the Bridge that Robin has mentioned.
You can see photos and details of Broadland Bridges on the NSBA site at http://www.thegreenbook.org.uk/home/bridges.asp
