I am delighted to have discovered the wonderful Paddlesteamers.info – a must-read for anyone with an interest or affection for these smooth-running, shallow draft vessels.
I developed a liking for them as a kid, when the (now sadly demolished) Lincoln Castle and the Tattershall Castle were working as ferries across the Humber, before the mighty and reliable but rather less interesting bridge was built.
There are pages about paddlesteamers in and out of service around the world, but I’ll include these links to working vessels around the UK: the lovely Kingswear Castle, the little Monarch (to my shame, I didn’t know she was built at Hoo in Kent) and the mighty Waverley.
