Hello,
Having just learned that the chain ferries were also called "reaction ferries" (used to know very well the Weserfähre, between Hann. Münden and Höxter), I found a very informative site (in German only, alas)
http://www.fjordfaehren.de/bi/binn.htm about inland ferries in Europe.
Couldnt this chain ferry be used in Cowes in ShipSim2008?
Regards,
Luc
