Russ,
did you get any suitable photos of the Tamar on the water? I have only seen one on the water,in a small portable pool,which was the super model made by Phil Locke. I hope you can get some more of your build before you depart for Aussie land, when is it you actually go,I seem to remember it is quite soon,so you will have to give your build watchers something to see before you go !
