I know the Aegean and Ionian seas pretty well. Particularly the Dodecanese islands: Kos, Kalymnos, Nisyros, Tilos, Rhodes, Limnos, Patmos, and the smaller ones... anyone looking for info I can help. I have no idea who charters what though... info on sea and other practical matters, e.g. harbours, marinas, waters, dangers, beaches, wind, legal issues (somewhat).
Western Port, Victoria, Oz (down in the bottom right-hand corner.) The northern part is shoal water, similar to the UK east coast in some ways, for which my YM 3-Tonner is ideally designed. The southern part opens into Bass Strait, which opens onto the world....
Photos available here. My 3-Tonner (Sanderling -- recognisable by her bilge-keels) features in two of the photos, and my clinker din ghy Aileen Louisa appears in the fourth.
