In order of reply, Allan, yes well believe it or not those blocks/chocks are actually oregan and were used as a "fore and aft" (basically a board that goes over some fenders to keep the vessel off the wharf) I salvaged after it was smashed by a boat after a storm in Hobart.
No worries Andy, I am glad you enjoyed it, It was great to review the experience and ponder if I know now what I knew then or knew now what I know then or whatever if I would do the same again, because while it probably reads that it went pretty much to plan, and looks like it did, anyone (maybe you too have the experience) will tell you it normally never does and it is a great exercise in problem solving etc etc etc with a bit more whatever on top of that etc.
And lastly Nool! I would send photographic evidence, but modesty stops me from doing so, plus the reflection off my head spoils the photo.

Re seeing the boat, I am certainly toying with the idea of taking it back to Narrandera next year, but make more of a trip of it, ie cruise the Yarra, go via Yarrawonga and then Narrandera, just an idea at the moment.
Cheers boyz.
