UK Inland Waterway Size Restrictions in English Units

Compiled by John Russell [email protected]. Converted from Excel to the web by Clive Worrall. John's comments: "All dimensions are in feet/inches. They are best guesses only and have been given in good faith. No guarantees. Many thanks to all those who have supplied me with the above details. I would be most grateful for any additional information which will be included in subsequent amendments. Please notify me of any errors or omissions."

Changes from the previous version (of May 2000): The changes are mainly to the Southern Oxford and the GUC (Northampton & Leicester arms) plus the Rivers Lee, Stort, Soar, Thames & Wey. I have also been asked by the Dutch Barge Association to include the River Medway, which is now featured.
