Thanks Bill, that is a very interesting bit of history, not only about Puppis but your own boat Maria, and Sonny. I didn't have the chance to chat to the occupants of Puppis back then as I was photographing from the road bridge at Preston Brook.
(and yes Derek R, they are my photos, so carry copyright, but that doesn't seem to make any difference nowadays does it? Several of my old canal shots from that period have been "pinched" off websites and used elsewhere, without so much as even a credit line. That's all I ask, I don't want money! I used to add a text copyright at the bottom of photos, but folk would just crop that out! But that's life nowadays, isn't it? I am just very pleased and content with the fact that others find some of my photos interesting)
