Man on the Ocean: A Book about Boats and Ships

by R. M. Ballantyne

And this is natural enough. Most boys delight to gaze on incomprehensible and stupendous works. Let us—you and I, reader—follow this urchin’s example, keeping our mouths shut, however, save when we mean to speak, and our eyes open.

There are ships here of every shape and size—from the little coasting-vessel to the great East Indiaman, which, in its unfinished condition, looks like the skeleton of some dire megatherium of the antediluvian world. Some of these infant ships have an enormous shed over them to protect them from the weather; others are destitute of such protection: for ships, like men, it would seem, are liable to vicissitudes of fortune. While the “great ones” of the dockyard world are comfortably housed, the small ones are not unfrequently exposed to the fitful buffeting of the rude elements even from their birth.

There are ships here, too, in every state of progression. There, just beside you, is a “little one” that was born yesterday. The keel has just been laid on the blocks; and it will take many a long day of clinching and sawing and hammering ere that infant assumes the bristling appearance of an antediluvian skeleton. Yonder is the hull of a ship almost completed. It is a gigantic infant, and has the aspect of a very thriving child. It evidently has a robust constitution and a sturdy frame. Perhaps we may re-visit the dockyard to-morrow, and see this vessel launched.

Besides these two, there are ships with their ribs partially up, and ships with their planking partially on; and in a more distant part of the yard there are one or two old ships hauled up, high and dry, to have their bottoms repaired and their seams re-pitched, after many a rough and bravely-fought battle with the ocean waves.

Now that we have gazed our fill at the general aspect of the dockyard, let us descend a little more to particulars. We shall first tell of the:—

Nature and Use of Docks.

There are two kinds of docks—dry and wet. A dry-dock is usually constructed with gates, to admit or shut out the tide. When a ship arrives from a long voyage, and needs repair to the lower part of her hull, she must be got out of the water somehow or other.

This object is frequently attained in regard to small vessels by simply running them gently on the flat sand or mud beach of a bay or harbour, so that, when the tide retires, they shall be left dry.

But it would be dangerous as well as inconvenient to do this with large ships, therefore dry-docks have been constructed for this purpose. They are so built that when the tide is full the dry-docks are also full. When thus full of water, the gates of a dry-dock are opened, and the large ship is dragged slowly in, after which the gates are shut. The tide then retires, leaving it in this basin of water. The ship is then propped up on all sides with timbers, in such a way that she stands upright, “upon an even keel,” and thus, the pressure on her hull being equally distributed, she is not damaged.
