THE

ELEMENTS AND PRACTICE

OF

NAVAL ARCHITECTURE:

Illustrated with a Roll of Thirty-eight large Draughts, and numerous smaller Engravings.

We have already noticed, in the preface to the present volume, that the above work developes, most fully, the principles of Ship-building, both theoretical and practical: that it describes, at large, all the various experiments which have been made for ascertaining the resistance of floating bodies, and the true theory thence arising. The practical parts of the subject are also, in their different ramifications, most fully and clearly described; particularly the subject of Laying-off in the MouldLoft, which, from its nature, will not admit of a copious and adequate discussion in a small treatise; this subject being illustrated with a particular series of large draughts, which exhibit, in the plainest manner ever yet seen, the arcana of this very important and essential branch of the

art.

In order, however, to give the reader a more satisfactory idea of the nature and value of this work, we annex the following abstract of its contents.

The whole of the letter-press is divided into Two Books; of which the first explains the Elementary and Theoretic Principles, and the second the Practical Rules of Construction, with all the requisite Tables of the Dimensions, &c. of no less than twenty-seven Classes of Shipping in the Royal Navy, and Merchant Service, besides Boats, &c. The First Book commences with an Explanation of Terms, and is succeeded by an Explanation of the Nature of Fluids and their Action on Floating Bodies, as ascertained by actual experiment, which is arranged as follow:

Of the Nature and Action of Fluids in general: Of the Resistance of Fluids: Experiments which have been made for determining the Resistance of Floating Bodies; especially of those made by order of the Society for the Improvement of Naval Architecture: General Observations on Vessels calculated to sail with great velocity; including a Description of the Flying Proa of the Ladrone Islands.

The Third Chapter treats of the Figure and Construction of Ships and Vessels in general, and on the means of giving them the most desirable qualities; with Remarks on the different Classes of British Shipping, thus:

General Observations: Definitions and Explanatory Remarks on the Motion of Vessels, &c.: On the Stability or Stiffness of Ships: To form a ship so as to steer well, and quickly answer her helm: To form a ship with such capacity as to carry her guns well above the water: Of the Form best adapted to go smoothly: On the Form best calculated to hold a good Wind, &c.: Observations on the whole of the Particulars described in the foregoing Sections, and on the proportioning of Ships' Bodies in general: Observations on the Construction of Ships, by Sir Geo. Shee, Bart. Member of the Royal Irish Academy: Remarks on the Formation of Merchant Shipping in particular, by Mr. Hutchinson : Of the Particular Advantages of Vessels constructed with Sliding Keels, and other Improvements, introduced by John Schank, Esq. a Captain in the Royal Navy, &c.: Remarks on the different Classes of British Shipping, including the new Life Boat, &c. especially on those of which the Draughts or Particulars are given in the Work.

The Second Book commences with General Observations and Definitions relative to the practical Construction of Ships; and proceeds, in its Second Chapter, with the Practical Methods of finding the Gravity, Displacement, and Tonnage of a Vessel; including the Centres of Gravity, and Displacement: with the point of Stability or Meta-centre: thence follow Instructions, at large, for delineating the several Draughts and Plans; which are elucidated by the larger plates. To these succeed a complete Explanation of the Methods of LAYING-OFF all the parts of the Ship on the Mould-Loft-Floor, preparatory to the actual construction, or building. This Chapter, elucidated by the Draughts, is arranged as follow:

Of Laying down the Sheer, Half-breadth, and Body Plans: Of the Moulds necessary to be made from the parts already laid down: To take the Bevellings of the Timbers in the Square Body: The Nature and Use of the Cant-timbers, with the Methods of laying them down by Water Lines: To Bevel the Cant-timbers by Water-lines: Of laying down the Cant-timbers by the Horizontal Ribband-lines: To lay down and take the Bevellings of the Cant-timbers by the Horizontal Ribbands: Of the Utility of the Transoms, with the Manner of Laying them down: Of

taking the Bevellings of the Transoms: To Lay-off the Transoms when canted: To Bevel the Transoms when canted: Of Laying-off the Square Tuck: To Lay-down and take the Bevellings of the Hawse-pieces, by Horizontal Lines: Of Laying-down and Bevelling the Hawse-pieces when they are required to be Sided less at the Heels: To Lay-down and Bevel the Hawse-pieces by Horizontal Lines, or the Horizontal Ribbands when canted: Of the Nature and Use of the Harpins, with the various Methods of Laying them off and taking the Bevellings: Of Laying-down the several Parts of the Head: Of Laying-down the several Parts of the Stern.

The succeeding Chapter explains the Method of Whole-Moulding; and is succeeded by Practical Directions for the actual Building, progressively arranged, viz. First, Directions for the various Parts of the Ship; Secondly, Directions for making Capstans and Windlasses; next, a complete Description of a Launch, with Explanation of the Methods of Launching; and concluding with a Description of a Fire Ship and Bomb Vessel.

The concluding Chapter of the Second Book is entiled "Miscellaneous "Observations on Improvements and Projected Improvements; including "some Instructions and Remarks upon Subjects immediately connected "with Naval Architecture." This Chapter contains, Explanation of a new Method proposed for the framing of Ships, and of the best Mode of adopting Iron Fastenings in their Construction: Observations on the Mode of improving the Navy; as addressed, in the Year 1796, to the Court of Directors of the Honourable East India Company, by the late Gabriel Snodgrass, Esq. with Notes and Remarks upon the same: Explanation of Mr. Sepping's New Method of Docking Ships: Some Remarks upon a Ship's Hogging, and the Means of prevention: On the Means of recovering foundered and stranded Ships: Description of several new Machines for driving and drawing Ship's Bolts, &c.: Observations upon Timber, with Rules for its Admeasurement and Conversion: Tables of the value of Timber.

Next follow the Tables for forming the Bodies of Ships and Vessels of each Class, and the Tables of the principal Dimensions and Scantlings, accompanied with such Directions as are necessary to the Practical Explanation of them; to which are annexed the Form of a Contract, entered into by a Merchant Ship-builder, for the Building of a Ship of War, for the Royal Navy; including the Dimensions of the Raven, Brig of War, built in the Year 1804.

The whole concludes with an Index to the Tables of the Dimensions and Scantlings, for the more readily constructing Draughts and Plans therefrom.

THE LARGER DRAUGHTS ARE AS FOLLOW.

I. Sheer-draught, Half-breadth and Body Plans, of a Ship
of Eighty Guns, upon two Decks.

II. Disposition of the Frame of the Eighty-gun Ship.
III. The planking expanded of the Eighty-gun Ship.,
IV. The Inboard Works of the Eighty-gun Ship.
