SHIP-BUILDING. 



breadth fpol on the half-breadth and body-plans, fgs. 9 

 and 8 ; then to al! thofe fpots pin a batten, and mark the curve 

 which (hall interfcft the bearding-Iine, and the fore-fide or 

 bevelllng-edge, d, of the fafhion-piece will be reprefented in 

 the body-plan, Jig. 8. 



The aft-fide and fore-fide appear now in their proper 

 fhape, in the body-plan, Jig. 8, and of the fame form as the 

 fafliion-piece, when trimmed and laid flat with the aft-fide 

 upwards, as then both edges will be feen, in confequence 

 of its being a (landing bevelhng ; therefore, the dillance 

 from the line rcprefents the aft-fide to the line of the fore- 

 fide, taking the neareft dillance, as at e, which will (hew how 

 much the beveUings are itandmg, or without a fquare, in 

 the breadth of the bevelliiig-board, which fhould be equal 

 to the fidiiig of tlie fadiion-piece. 



When the mould is made to the ticked line, c, of the aft- 

 fide, the heel of it mull be cut off well with the line for the 

 feating of the tuck, and likcwiie well with the middle line, 

 in order th-at it may dovetail and bolt into the ftern-poll. 

 Mark alfo on the mould the bearding-line, ©r fide of the 

 inner poll. The different firmarks for the ribbands mull be 

 marked on the moulds ; but, in order that the (lations of 

 the ribbands may be correftiy marked, obferve where the 

 diagonal lines interfeft the horizontal view of the tuck a> in 

 the body-plan, Jig. 8, and carry them up parallel to the 

 middle line, to the line for the aft-fide of the fa(hion-piece c, 

 to which the mould is made. This will be their proper (la- 

 tions or upper fides, and may thence be marked on the 

 mould. 



The bevellings may be taken at the different firmarks or 

 ribbands, and fet off where taken, as the bevel at the fe- 

 venth ribband, which will (liew it more clearly. The ticked 

 line g, drawn parallel to the flock of the bevel, is the fame 

 oittance from the outfide of the bevel, as the fa(hion-piece is 

 lided. Then draw aline fquare from the (lock of the bevel 

 to the ticked line ^^r ; and where it interfefts the ticked line 

 -,', as at h, fet ofi from h to i the fame didance as the fore- 

 fide is from the aft-fide at that place, as before direfted, 

 ind open the tongue of the bevel to i. This will (hew the 

 ncvelling of the fafhion-piece at that place. The bevel is 

 to be applied fquare from the moulding edge. 



Run in the half-breadth plan, fig. 9, the diagonal 7, al- 

 though the ending of it only differs from thofe explained 

 before, and need only be delcribed. Transfer the height 

 Irom the body-plan, j^j'. 8, where the diagonal 7 interfefts 

 tlie horizontal view of the fa(hion-piece a, and fet it up in 

 the (heer-plan, _y{V. 7, at the aft-fide of the fafliion-picce ; 

 and from its interfedtion there, iquare it down to the half- 

 breadth plan, ^_f. 9 ; then take its diftance in the body- 

 plan, fig. 8, from the middle line to the horizontal view of 

 the faihion-jiiece n, in its diagonal direftion, and (et it off 

 from the middle line, in the half-breadth plan, on the line 

 f()uared down, which gives its ending at the fafhion-piece. 

 In the fame manner transfer its height where it interfefts the 

 upper fide of the wing-tranfom, in the body-plan, _/[f. 8, 

 and fet it up in the (heer-plan, Jig. 7 ; and where it inter- 

 fcfts the aft-fide of the fafiiion-piece, fquare it down to the 

 half-breadth plan, ^^y. 9; then take the dillance from the 

 middle line, in the body-plan, Jg. 8, as before, to the upper 

 fide of the wing-tranfom, and fet it oft from the middle line, 

 in the half-breadth plan, fig. 9, on the line latl fqnared 

 down ; then mark a line tlirough thofe fpots, as the long- 

 ticked line a, in the half-breadth plan, f:g. 9, which will be 

 the true ending of the diagonal 7, or any diagonal crofhng 

 tlie wing-tranfom and fafhion-piece. 



Square tucks of lighter* are like thofe above defcribed, 



and the tranfoms of boats are laid off in a fimilar manner, 

 but compofed of only one piece athwattfhips, and their 

 upper fide is bounded by the upper fide of the flieer. But 

 the tucks of yachts (or frigates, if built of fir) partake of 

 the round-forward of the wing-tranfom, which caufes the 

 fafhion-pieces to take a part of it alfo the whole of their 

 length, which makes them rather more difficult to be laid 

 off. But, fuppofing the former to be clearly underilood, 

 we (hall give a defcription of a tuck, the outfide of which 

 is to round-forward, in its finifhed (late. 



Suppofe a flat furface, of thin deal (in length from the 

 head of the fafhion-piece or height of breadth to the feating 

 of the tuck, and in breadth to the outfide of the tranfom) 

 was placed with one edge to the rabbet of the poil, and the 

 other edge bent round to a curve, as much as the outfide of 

 the tuck is intended to round-forward, in which pofition 

 fuppofe it to be confined ; then draw the fhape of the out- 

 fide of the tuck or fafliion -piece down to the poll, and cut 

 it out. The true fhape of tlie tuck or fafhion-piece is now 

 (hewn as it is to be trimmed, and as it will appear in its 

 finifhed (late. Then take it from its pofition, and lay it 

 flat, letting the round be unconfined ; and it will then ap- 

 pear as it is required to be laid ofi" in the body-plan, in order 

 to make the mould therefrom. 



The fafhion-pieces for the fquaie tuck being already laid 

 off, the fame horizontal lines, &c. may be transferred to 

 the (lieer and body-plans, ^^j. 10 and 11 ; then proceed to 

 lay it ofi' upon the flat, agreeable to the rake of the rabbet 

 of the ftern-polt, as before diredted, witii this difference, 

 having no round-aft made, but one flraight line in the 

 thwartfliip view, in the fliecr-plan. Jig. 7, wiiich was the 

 aft-part of the rabbet of the flern-poft ; but, in the prefent 

 fquare tuck, where the head of the faftiion-piece is carried 

 forward, to conneft with the end of the wing-tranfom, the 

 moulding edge of the fafhion-piece forms a ferpentine line. 



Therefore, where each horizontal line interfcifts the aft- 

 part of the rabbet of the pofl a, in the flieer-plan, fig. 10, 

 fquare down the didances to the middle line of the half-breadth 

 plan,^^. 12, making of fpots; then upon the horizontal line, 

 No. 5, at the height of the wing-tranfom, at the fide, fet 

 off from the aft-fide of the rabbet of the pofl a, the round- 

 forward of the wing-tranfom, in the fhecr-plan, ^^. 10, and 

 fquare it thence down to the half-breadth plan, //jr. 12; 

 upon which fet off the half-breadth of the wing-tranfom, 

 and thence fweep a curve, the centre of whofe radius being 

 in the middle line, (hall cut the (pot for the laid horizont5 

 line, in the middle line of the half-breadth plan, ^]y. 12, 

 which will reprefent the aft-fide of the wing-tranfom a, at 

 the height of the horizontal line at the fide- Now, from 

 the other fpots fquared down on the middle line of the half- 

 breadth plan, fweep curves with the fame radius, and they 

 will be parallel to the curve of the wing-tranfom a. Tlie 

 horizontal lines being transferred from the half-breadth 

 plan, ^^. 9. 10 Jig. 12, take the diflances fquare from the 

 middle line in the half-breadth plan, ^_f. 12, to where the 

 horizontal lines interfeft their rclpedlive curves for the aft- 

 fide of the tuck, and fet them off from the middle line on 

 their corrcfponding horizontal lines, in the body-plan, 

 Jig. 1 I ; a batten pinned to thofe fpots will fiiew the hori- 

 zontal view of the tuck <;, in the body-plan, fig. i i. Alfo, 

 where the horizontal lines in the half-freadth plan,yff . 1 2, iii- 

 tcrfeft their relpedtive curves, fquare I he diltaiices up to their 

 corrcfponding horizontal lines in the (heer-plan, /r^'. 10; 

 and by drawing a curve to pafs through tliolt Ipotn, the 

 thwarllhip view of the aft-fide of the falhioii-picce, b, will 

 be reprefented in the fhcer-plan, _/fj. 10; and what the
