From the sheet:
THE RAJAH'S PLEASURE BOAT.

The engraving, given below, represents the pleasure boat of the rajah of Johore. It is a fine, trim craft, and built on scientific principles for speed-from the mode of sailing in use among the Malays (standing on the weather gunwale). These boats can carry a very large press of canvass, and thus make great headway. The rajah's pleasure boat is built after the modern rules of ship-building, or that, at least, adopted for clippers, thus, the greater the speed required, the greater should be the length, and the vessel should be built merely of the breadth necessary to stow the requisite cargo. The greatest width of the water line, instead of being before the middle, is abaft the middle of the vessel-in fact, two-fifths from the stern and three-fifths from the bow. Substituting for broad, bluff, or cod's head bow, hollow water-lines, called wave-lines, from their particular form ; and instead of the old fine run abaft, and cutting it away, having a fuller line abaft, with fine line under the water. All the fast steamboats, accomplishing from sixteen to seventeen miles an hour, are built on this principle. Thus it will be seen that the great modern improvements in ship-building are being extended even to these distant regions of the globe, and most successfully.[2]
