I think this one, (100045E) is on the Main-Donau Canal.
Pages 25 - 28 were mainly taken during May 2010 in The Netherlands. Not certain of all the locations as Ian often went off on his own or on a different trip to myself, but, starting at 100764 were taken in The Netherlands. 1000770E was taken by the entrance hall of the Rotterdam Foot Tunnel under the Maas. Splashtours are a Rotterdam feature. 1000771E to 1000773 show the SS Rotterdam, formerly the Holland America ship based in Rotterdam and now moored up permanently as a Hotel and attraction. 1000774 shows the Erasmusbrug, better known as the Swan, across the Maas in Rotterdam. 1000776 shows the Eefde sluis on the Twente Canal, Netherlands, near Enschede. as do 10077E and 10078E. 100783 - 1000787 show the Zutphen Railway bridge which has a lifting section need by hotel ships for clearance, but not by most barges. Switzerland 11 is shown waiting to go through the lifted section. Will have to pause here and look through another page.
