Excerpt from A Brief Sketch of the Plan and Advantages of a Sectional Floating Dry Dock: Combined With a Permanent Stone Basin and Platform, and Connected With Level Bedways, Sliding Ways, and Housed Slips, for Repairing, Launching, and Laying Up in Ordinary, the Ships of the United States NavyAgain: These covers have been in use in Venice, from time immemorial, and Mr. Strange, the British Consul at that port, in 1792 says, that he saw twenty-two large ships laid up there under covered Slips, some of which had lain there for sixty years.Again: The advantages which Slips are supposed to possess over Dry Docks, are many and important. They can be constructed at one twentieth part of the ex pense, they occupy less space, they can be constructed on a steep or a shelving shore, and ships can be hauled upon them either in spring or neap tides, whereas a Dry Dock can only be made in particular situations, and when made, ships can only be docked and undocked, in certain states of the tides, from which circum stance considerable delay and inconvenience are frequently experienced. It should be recollected, however, that a large ship must necessarily go into a Dock preparatory to her being hauled out in the Slip. It has been considered not at all improbable, as was suggested sometime ago by Mr. Perring, that the whole Ordi nary may hereafter be laid on Slips, which, if housed over, would unquestionably be the best means of increasing their durability, and preserving them from partial decay. Nor is it certain that in the end, it would not be the most economical.It will be seen that it is fully admitted in England, that many serious objections exist against the present system of Excavated Docks which were constructed at a time when no other method was known for taking ships out of the water. These defects we now propose to remedy in a great measure by the introduction of a new plan of Dock, Basin, Bed and Sliding Ways.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
