Wineglass Bay, Port | Arthur, Bruny Island - here we come. ============================== Visiting Bruny Island, Peter should not miss the little museum, facing the sea at Adventure Bay, devoted to the many famous navigators who stopped there and watered their vessels at the nearby stream. Bruny Island is an hour-glass shape with a wasp-waist that's hardly wider than the little roadway, and seems to be in great danger of a breach. Hope it hasn't happened yet. The ferry vessel, across d'Entrecastaux strait, is of some interest also. As well as I can remember, it's driven by Voith-Schneider propellers, which spin about a VERTICAL axis under each end. The pitch alters as they rotate, rather like the blades of a helicopter, allowing them to eject water in any direction the captain fancies. This makes the vessel infinitely manoevrable. Some tugs use that system, as does the Lymington - Yarmouth ferry, across the western Solent, in the UK. That flat-bottomed ferry can perform evolutions which can, and often does, take yachtsmen by surprise.
