Shipbuilding in iron and steel / a practical treatise . . all cases, where centre continuous plates are applied, theyare to be extended to the stem and stern post, and connectedthereto, where practicable. As these Eules regulate the greaterpart of the practice of the mercantile shipbuilders, we shall notenter here or indeed, at all, upon the details of the dimensions andproportions to be given to the various parts of merchant vessels, but shall give the Eules themselves, and the well-known Table Gr, in the form of an Appendix. We shall also add the Eules of theLiverpool Underwriters Eegistry. The flat-keels, which have been given to H.M. iron-cladfrigates differ from those already described chiefly in the fact thatthe flat-keel plates are doubled in them, the garboard-strakesmeeting the inner-keel plate, flush with it, and the outer-keel platebeing worked broadenough to lap uponthe garboards, as shownin Fig, 32, which is asection of the War-riors keel and keel-son-plates. Here thecontinuous centre-plateis 40 inches deep andI inch thick, and is. Fig. 32. connected below to the two keel-plates by 6-inch angle-irons1 inch thick, and above by two smaller irons (31 inches by3^ inches by f inch) to a flat-keelson plate f inch thick and3 feet broad. These latter angle-irons are in short lengths, between the floors, as the upper pair of the floor angle-ironsand the shallow plate between them run continuous across thecentre plate, into which they are scored. The outer angle-ironsof the floors turn up against the centre continuous plate. Theouter and inner keel-plates have each a short butt-strap worked oneach side of the keel angle-irons, and the butts of the angle-ironsare also covered in the usual way. The keel-plates are in lengthsequal to the other plates of the bottom, as are also the vertical 32 Keels. Keelsons. Chap. II. middle-line plates. The angle-irons are in length from two to fourlengths of the outside plating. The keel arrangements of the Northumberland are of
