Two Years to Build, Twenty Seconds to Launch

🚢 A ship in the water is a thing you cannot see. The waterline is a line somebody drew, and below it there is a third of the vessel you will never look at as long as it is doing its job. There are two moments when that is not true: when it is being built on blocks on dry land, and when it is hauled out again to be repaired. Everything in this film comes from one of those, or from the twenty seconds in between when it slides down the slipway. ⚓ A dry dock is a hole in the ground with a gate. Flood it, float the ship in, shut the gate, pump it out, and the hull settles onto blocks that had to be positioned beforehand to match that exact shape, because steel resting on the wrong points will deform. Then you walk underneath it. That is the entire reason dry docks exist. 📸 And the reason the archive looks the way it does is the camera. A launch happens at a time announced in advance because the tide decides it, outdoors, in daylight, with an enormous high-contrast subject that stays put all morning and a crowd who will buy prints. Photographing a riveting gang inside a dark hull full of smoke, with burning magnesium for light, is the opposite of all of that. So every shipyard archive on earth is heavy on launches and docks and light on work. 🔥 The film also covers what is not finished when a ship is launched, the arithmetic that stops a hull breaking its own back on the way down, why a bottle that does not break is bad luck, riveting and the welding that replaced it, the several hundred thousand women in American shipyards in the Second World War, and the USS California, which was raised out of the mud at Pearl Harbor, dry docked, rebuilt and sent back to the war. 📷 Every picture in this film is a real archive photograph.
