James Curwood - The Great Lakes.The Vessels That Plough Them

It is only natural that these conditions should have developed shipbuilding on the Lakes to a science unparalleled in any other part of the earth. I once had the good fortune to talk with a shipbuilder from the Clyde. He had heard much of the Lakes. He had built ships for them. He had heard of the wonders of shipbuilding in their cities. So he had come across to see for himself.

“I had thought that your ships would not compare with ours,” he said. “You build them so quickly that I thought they would surely be inferior to those of the Clyde. But they are the best in the world; I will say that – the best in the world, and you build them like magicians! You lay their keels to-day – to-morrow they are gone!”

This is almost true. A ten-thousand-ton leviathan of the Lakes can now be built almost as quickly as carpenters can put up an eight-room house. Any one of several shipyards can get out one of these monsters of marine commerce within ninety days, and the record stands with a ten-thousand-ton vessel that was launched fifty-three days after her keel was laid! One hardly realises what this means until he knows of a few of the things that go into the construction of such a vessel. Take the steamer Thomas F. Cole , for instance, launched early in 1907 by the Great Lakes Engineering Works. This vessel is the giant of the Lakes, and is six hundred and five feet and five inches long. She is fifty-eight feet beam and thirty-two feet deep, and in a single trip can carry as great a load as three hundred freight cars, or twelve thousand tons. In her are nine million five hundred thousand pounds of iron and steel! What does this mean? It means that if every man, woman, and child in Indiana, Michigan, Wisconsin, and Minnesota were to join in carrying this material to a certain place, each person would have to transport one pound. In the mass would be eight hundred thousand rivets, ranging in size from five eighths of an inch to one and one eighth inches in diameter.

One who is investigating Lake shipbuilding for the first time will be astonished to discover that the modern freighter is in many ways a huge private yacht. They are almost without exception owned by men of wealth, and their cabins are fitted out even more luxuriously than those of passenger boats, for while these latter are intended for the use of the public, the passenger accommodations of freighters are planned for the friends and families of the owners. So above the deck which conceals ten thousand tons of ore the vessel may be a floating palace. The keenest rivalry exists between owners as to who shall possess the finest ships, and fortunes are expended in the fittings of cabins alone. Nothing that money can secure is omitted. In the words of a builder: “The modern freighter is like a modern hotel – only much more luxuriously furnished.” There is an electric light system throughout the ship; the cabins are equipped with telephones; there is steam heat; there are kitchens with the latest cooking devices, elegantly appointed dining-rooms; there are state-rooms which are like the apartments in a palace, and other things which one would not expect to see beyond the black and forbidding steel walls of these fortune-makers of the Lakes.

With the first peep into modern methods one realises that the romantic shipbuilding days of old are gone. No longer does the shape, beauty, and speed of a vessel depend upon the eyes and hands of the men who are actually putting it together. For the ship of to-day is built in the engineering offices. In the draughting-room skilled men lay out the plans and make the models for a ship just as an architect does for a house, and when these plans are done they go to a great building which reminds one of a vast dance hall, and which is known as the “mould loft.” Seemingly the place is not used. Yet at the very moment you are looking about, wondering what this vacancy has to do with shipbuilding, you are walking on the decks of a ship. All about upon the floor, if you notice carefully, you will see hundreds and thousands of lines, and every one of these lines represents a line of the freighter which within three or four months will be taking her trial trip. Here upon the floor is drawn the “line ship” in exactly the same size as the vessel which is to be built. Over certain sections of this “line ship” men place very thin pieces of basswood, which they frame together in the identical size and shape of the ship’s plates. By the use of these moulds, or templates, the workman can see just where the rivet holes should be, and wherever a rivet is to go he puts a little spot of paint. These model plates are then numbered and sent to the “plate department,” where the real sheets of steel are made to conform with them and where the one million five hundred thousand or more rivet holes are punched. With the plates ready, the real ship quickly takes size and form.

Some morning a little army of men begins work where to the ordinary observer there is nothing but piles of steel and big timbers. From a distance the scene reminds one of a partly depleted lumber yard. On one side of this, and within a few yards of the water of a slip, are first set up with mathematical accuracy a number of square timbers called “keel blocks.” Upon these blocks will rest the bottom of the ship, and from them to the water’s edge run long shelving timbers, or “ways,” down which she will slide when ready for launching.

Children frequently play with blocks which, when placed together according to the numbers on them, form a map of the United States. This is modern shipbuilding – in a way. It is on the same idea. There is a proper place for every steel plate in the yards, and the numbers on them are what locate them in the ship. A giant crane runs overhead, reaches down, seizes a certain plate, rumbles back, to hover for a moment over the growing “floor,” lowers its burden – and the iron workers do the rest. Within a few days work has reached a point where you begin to wonder, and for the first time, perhaps, you realise what an intricate affair a great ship really is, and what precautions are taken to keep it from sinking in collision or storm. You begin to see that a Lake freighter is what might be described as two ships, one built within the other. As the vessel increases in size, as the sides of it, as well as the bottom, are put together, there are two little armies of men at work – one on the outer ship and one on the inner. From the bottom and sides of the first steel shell of the ship there extend upward and inward heavy steel supports, upon which are laid the plates of the “inner ship.” In the space between these two walls will be carried water ballast. The chambers into which it is divided are the life-preservers of the vessel. A dozen holes may be punched into her, but just as long as only this outer and protecting ship suffers, and the inner ship is not perforated, the carrier and her ten-thousand-ton cargo will keep afloat.

When the construction of the vessel has reached a point where men can work on the inner as well as the outer hull, it is not uncommon for six hundred to eight hundred workmen to be engaged on her at one time. Frequently as high as one hundred gangs of riveters, of four men each, are at work simultaneously, and at such times the pounding of the automatic riveting machines sounds at the distance of half a mile like a battery of Gatling guns in action. So the work continues until every plate is in place and the vessel is ready for launching, which is the most exciting moment in the career of the ship – unless at some future day she meets a tragic end at sea. One by one the blocks which have been placed under her bottom are removed, until only two remain, one at each end. Then, at the last moment, these two are pulled away simultaneously, and the steel monster slides sidewise down the greased ways until, with a thunderous crash of water, she plunges into her native element.
