Is it the knowledge of position or the motor that makes the difference? To put that another way: Was Bass Strait a problem for an under-manned, deep-laden, sailing grain carrier out of Spencer Gulf because her captain had only an imprecise knowledge of his position? Or was it a problem because a ship that cannot sail within six points of the wind, when tacking ship is a slow and uncertain process, wants a lot more sea room than can be found between the islands at the eastern end of the Strait? I don't know the answer. Peter continued: > King Island (in Bass Strait) was a notorious collector of ships. Though mostly of ships bound for Melbourne. They had no option but to enter the Strait from one end or the other. In a separate posting, George asked: > I think that the lighting of King Island must have made a big difference to > the attraction (or otherwise) of Bass Strait. Anyone know when that > happened? Not I. As an uncertain terminus post quem, West's "History of Tasmania" of 1852 makes very little mention of activity on "King's Island", save for that of the early sealers. I would take that as a strong indication that nothing as advanced as a lighthouse was to be found there before 1850. Then again, until gold was found in Victoria, there wasn't that much shipping bound into Bass Strait and so not much justification for the expense of lights so that date in no surprise. Apropos of low-tech navigation methods: Bass Strait was not proven to be a strait until Kelly circumnavigated Tasmania in a whale boat in 1815. (Quite a feat in itself.) Bass and Flinders had seen the eastern entrance in, I think, 1798 but nobody seems to have wanted to sail through in a ship, which was perhaps wise since had there not been a strait, the luckless explorer would have been embayed with a shore stretching from near Adelaide to South West Cape under his lee. Bass and Flinders nevertheless suspected that there was a strait between Tasmania and the Australian mainland because of the heavy swell that was rolling through and which seemed too great to be formed within a closed bay. By such hints could an experienced seaman in a small vessel judge the shape of sea basins long before they were charted. Trevor Kenchington -- Trevor J.
