Great display. Reminds me of when I was very young, in the 1960s going to visit Granny in Dagenham. Sometimes our route would take us near the Thames and I can remember, even then, being struck by the unique and pleasing shape of the tugs. Seeing the tugs was something I always enjoyed. Perhaps it is a generational thing, but these older tugs, and Clyde puffers for that matter, seemed to have more character (a personality almost) that later boats seemed to lack.
