SHIP-BUILDING. 



the middle line, through which heights draw a curve parallel 

 to the gun-deck, and another curve three inches parallel 

 above it, and the upper deck will be reprefented at the 

 middle line of the (heer-plan. 



Theftern-timberslhould be next drawn, to (hew the bound- 

 aries of the (heer-plan above the wing-tranfom. Set up 

 above an horizontal line drawn at the upper fide of the wing- 

 tranfom at the middle line four feet, upon a perpendicular 

 6 feet lo inches abaft the aft-fide of the wing-tranfom, 

 which will be the height and knuckle of the lower counter at 

 the middle line; from thence draw a curve, about fix inches 

 hollow, to the upper fide of the wing-tranfom, where the 

 fore part of the rabbet of the Itern-poil interfeds it ; and 

 that curve will reprefent the lower counter at the middle 

 line. 



In the fame manner, fet up the height of the upper 

 counter 7 feet 5 inches, upon a perpendicular nine feet abaft 

 the aft-fide of the wing-tranfom, which will be the lieight 

 and knuckle of the upper counter at the middle Une ; then 

 drawing a curve about one inch hollow from thence to the 

 knuckle of the lower counter, the upper counter will hke- 

 wife be defcribed at the middle line. 



Having the upper and lower counters drawn at the middle 

 line, the upper part of the llern-timber is ilraight above 

 the upper counter, and muft be drawn as follows : 



Setup 23 feet 8 inches, upon a perpendicular 14 feet abaft 

 the aft-fide of the wing-tranfom, as before, and then drawing 

 a ftraight line from the knuckle of the upper counter, to 

 pafs through the faid fpot, the upper part of the itern- 

 timber will be (hewn at the middle line, by which the rake 

 of the ftern will be defcribed. 



As the ftern rounds two ways, both up and aft, (or for- 

 ward from the timber already drawn,) the ilern-timber at the 

 fide muft alter fo much from that at the middle hne, and 

 therefore remains to be reprefented. Set down from the 

 knuckle of the upper counter on its perpendicular 9 inches, 

 and draw an horizontal line before it at that place, and fet 

 off thereon 15 inches from the faid perpendicular, which 

 will be the knuckle of the upper counter at the fide the 

 9 inches is the round-up, and the 16 inches the round-aft at 

 the upper counter. Then proceed in like manner for the lower 

 counter, by fetting down 9 inches, and forward 15 inches, 

 and the knuckle for the lower counter at the fide will be pro- 

 duced ; then, by drawing a curve from the knuckles at the 

 fide (fimilar to the curve or hollow at the middle line), ob- 

 ferving the lower counter at the fide is drawn to interfeft the 

 touch of the wing-tranfom at the fide, the fide ftern-timber 

 only wants the upper part to complete it. But as the 

 Itraight line, which remains to be drawn for the upper part 

 of the fide-timber, (hould not be parallel to that at the mid- 

 dle line, the following method will determine the exaft rake 

 thereof. 



Draw a ftraight line at pleafure, as the ticked line under 

 the body -plan, on which fet off the breadth of the ftern at 

 the upper counter, or 13 feet 4 inches, equally on each fide 

 of the middle hne ; and there fquare up a perpendicular on 

 each fide : fet up from the ftraight line i6 inches, the 

 round-aft of the upper counter on each perpendicular, and 

 draw a fegment of a circle that dial] interieft thofe fpots 

 and the ftraight line at the middle, and the round-aft of the 

 ilern will be defcribed at any part of the breadth above the 

 upper counter : thus, take the breadth of the ftem at the top 

 timber-line, which is 24 feet 8 inches above the wing-tran- 

 fom, which is 24 feet, and fet it off equally on each fide the 

 middle, to where it (hall interfcft the round-aft under the 

 "body-plan ; thence draw a line parallel to that firft drawn, 

 and the diltance between the two lines, 1 3^ inches, is the 



diftance that the fide-timber will be from the middle-timber 

 on an horizontal line, at the height of the top timber-line, 

 draw a ftraight line through the laft (pot fet off to interfeft 

 the knuckle of the upper counter at the fide, and that will be 

 the rake of the fide counter-timber, as (hewn by the ticked' 

 lines in the (heer-plan, Plate I. 



The rake of the ftern-timbers being determined, proceed 

 to finifli the decks. Set up from the upper fide of the upper 

 deck 6 feet 10 inches at the middle ftern-timber, and 6 feet 

 8 inches fore part at frame 8, and above that 3 inches, 

 drawing curves as before, and the quarter-deck at the mid- 

 dle line will be reprefented. 



Proceed in the fame manner with the round-houfe abaft. 

 Set up from the upper fide of the quarter-deck 6 feet 8 inche» 

 at the middle ftern-timber, and 6 feet 6 inches at fore part 

 or frame 24, and above that z\ inches. The forecaftle 

 forward is reprefented in the fame way, by drawing curves, 

 one parallel to the upper fide of the upper deck 6 feet 7 

 inches above it, and another at 3 inches from the beak-head 

 to frame D. 



All the decks having been drawn, reprefenting their 

 heights at the middle line, their heights at the fides differ 

 from the former, agreeable to the round of the beam ia 

 the breadth of the (hip : to do which correftly, take the 

 round-up of the beam of its refpeftive deck, fay the 

 gun-deck, 6 inches, and fet it up in the middle of any 

 Ilraight line, fo that the half-breadth in midfhips at the 

 height of the gun-deck may be fet off on each fide on the 

 line. Then raife the fegment of a circle that (hall interfeft 

 the round-up at the middle, with the fpots at the breadth, 

 and the round-up of the deck will be defcribed at any part of 

 its breadth. Thus, take the half-breadth at the height of 

 the deck at any timber in the body-plan, and fet it off 

 equally from the middle of the round-up till it interfefts the 

 curve ; whence draw a line parallel to that firft drawn, and 

 the diftance between the laft line to the round-up in the 

 middle is what the beam rounds at that place : tkus may the 

 round-up be taken at as many timbers as may be found ne- 

 ceflary, and fet below the under fide of the deck, at its re- 

 fpeftive timber in the (heer-plan ; then a curved line paffing 

 through thofe fpots, will reprefent the deck at the fide : but 

 obferve, that the decks are to have a fufficient round abaft, 

 to correfpond with the round-up of the ftern above the 

 lights, and that the additional round wanted to be fet down 

 at the fide line. 



The (heer or top timber-line may be next drawn, by fet- 

 ting up its height in the (heer-plan afore in midfliips, and 

 abaft : thus, at timber X forwards, 37 feet 8 inches ; at i^ 

 in mid(hips, 35 feet 4 inches ; and at the fide (tern-timber 

 abaft, 41 feet 6 inches : then, by drawing a curve through 

 thefe fpots, as in Plate I. the (hccr of the (hip, or top-timber 

 line, will be reprefented. 



The ports may now be drawn in the (heer-plan, thus : 

 draw two curves in pencil parallel to the deck at the fide, 

 fore and aft, adding the thickncfs of the deck to that already 

 drawn, as that reprcfents the under fide of the deck, or 

 upper fide of the beam. The gun-deck ports are to be 

 2 feEt4 inches from the upper fide of the gun-deck plank to 

 the upper fide of the lower fills, 2 feet 8 inches deep, 

 and 3 feet 5 inches fore and aft, or from the fore to the after 

 fides, which may now be fquaied up between the lines laft 

 drawn ; placing the fore-fide of the forcmoft port I foot 

 5 inches abaft timber X, and 3 feet i inch only on athwart- 

 (hip line ; the afc-fide of the after-port to be 14 inches 

 afore timber 32, and the fore-fide 3 feet 5 inches afore 

 it, or in the clear ; and the remaining 1 3 to be 7 feet 7 inches 

 afunder. In the fame manner draw in the upper deck ports, 



which
