| 説明 | Here's the Balclutha's engines - she's like that Finnish ship in "The Great Grain Race" - steel hull and masts, wire-rope rigging, mast height WAY up there (The Finnish ship topped out at 200' above sea level) A curious moment we don't think a lot about these days, when it was obvious that a riveted, steel, hull, was a practical and economically attractive way to build a cargo ship, which would be propelled by sails. Of course, your passages are then dependent on the wind, and some become seasonal. And it takes 20 seamen to run the sails. And you'll chip and paint continuously, with red-lead primer. But the strength of steel allows the ship to be MUCH bigger, conveniently. (There are good reasons nobody ever built a 1000' wooden ship) So your fixed costs are distributed over a larger volume. With her steam engines and paddle wheels, and 5 masts for smaller sails, the Great Eastern never made economic sense. Balclutha managed to pay her way to the end of the line, and beyond, and like Star of India down in San Diego, she survived, after 100 others (or more) went to the breakers, to be recycled. Just like their wooden fore-bearers.DSC_0401 |
