For which you presumably need Admiralty Chart 109 River Humber and the Rivers Ouse and Trent available from http://www.imray.com/record.cfm?i_stock_code=AC109 or http://www.bookharbour.com/epages/BookHarbour.sf/en_GB/?ObjectPath=/Shop s/BookHarbour/Products/0109. The latter gives a reasonable scale online preview of the chart. David Mack
