SHIP-BUlLDINa 



of the tranfom, after the end is cut off, in order to countcr- 

 moulcl the tranfom, proceed in the following manner. 

 Where the upper and lower fides cf the lower tranfom intcr- 

 feft the after-cant-fafhion-piece P, in the body-plan, 

 jig. 5, level them out to interfeft the after-cant-fafhion- 

 piece O. Where the upper fide of the lower tranfom 

 interfedfs the perpendicular ticked line K (which is the 

 after-fafhion-piece in the fheer-plan, _/^. 4), transfer that 

 height to the middle line, in the body-plan. Jig. 5 ; and 

 from thence draw a flraight line to the upper fide of 

 the lower tranfom, on the cant-fafhion-piece, as the ticked 

 line e ; to which line fix the Hock of a bevel, as at B, 

 and the tongue to the cant-fafhion-piece O, as low down 

 as the fpot for the lower fide of the tranfom. This is 

 the proper bevelling to be applied on the end of the 

 tranfom, after the end is cut off, in order to counter-mould 

 the tranfom. The ticked line e, to which the flock of the 

 bevel is placed, is the direClion of the tranfom to be crolied 

 on the fafhion-piece mould. The bevel B, which is repre- 

 fented in the body-plan, _/[j. 5, (hewing the bevelling of the 

 end of the lower tranfom, fufficiently proves the utility of 

 canting the tranfoms ; for, by having fo little bevelling, 

 it greatly alfifts the converfion of timber, as well as that it 

 mull certainly be better for the fecurity of the plank of the 

 buttock. 



To Lay-off a Square-Tuck, Plate IX. Laymg-offQ.. 



We have already explained the utility of the tranfoms in 

 compofing the ftern-frame, by which method moft fhips are 

 inclofed abaft. But yachts and cutter-built vefiels are, 

 owing to their clearnefs of run abaft, inclofed by a fquare 

 tuck, by which room is gained ; and, when properly put 

 together, this mode of conllruftion is, perhaps, ftronger 

 than tranfoms would be in veflels of this defcription. 



The tuck propofed to be laid off is that of the royal 

 yacht, Plate XIII. But that the reader may be led pro- 

 greffively on from the cafieft to the moft difficult part of 

 the operation, we (hall iirlt propofe a fquare tuck, the 

 fides of which are to be out of winding, or in the fame 

 diredion as the rabbet of the poft, in confequence of which 

 the wing-tranfom mull be (traight athwartfhips, and the 

 whole will be one flat furface ((imilar to the tranfoms of 

 boats), or a fedtion of the veffcl cut athwartfhips, but not 

 in a perpendicular direction, which is the only difference 

 between it and the fquare timbers ; and as the fe£lion is 

 agreeable to the rake of the llern-poft, it confequently 

 follows, that the laying it off rauft differ from the fquare 

 timbers in the operation. 



The horizontal view of the tuck muff firft be reprefented 

 in the body-plan, yfj. S, wliich is done in the Ibllowing 

 manner: ftrike a horizontal line in the (lieer-plan, _/?^. 7", 

 at the height of the wing-tranfom at the fide, as at 5 ; and 

 likewife as many horizontal lines below that as may be 

 tliought fufficient ; and where they interfeft the aft-part of 

 the rabbet of the poll a a, fquare them down to the half- 

 breadth plan, Jig. 9 ; then transfer their heights to the 

 body-plan, fig. 8 ; and where they interfeft the fquare 

 timbers 21, 22, 2^, 24, 25, and P'l, in a horizontal di- 

 reftion, take thole diilances from the middle line, and fet 

 them off upon their correfponding timbers from the middle 

 ^ line, in the half-breadth plan, fig. 9 ; then by pinning a 

 batten to thofe fpots, the horizontal lines 1,2, 3, 4, 5, 

 and 6, will be reprefented ; then take their diilances from 

 the middle line, in the half-breadth plan, fig. g, where they 

 interfeft the fines fquared down from the ftiecr-plas, and fet 

 them off from the middle line on their correfponding hori- 

 aontal lines, in the body-plan, fig. 8 ; then by pinning a 



batten to thofe fpots, the horizontal view of the tuck, at 

 will be reprefented in the body-plan, fig. 8, as high as the 

 wing-tranfom at the iide. But was the head of the faihion- 

 piece required to run up, to take a bolt or two through the 

 heel of the fide counter-timber, proceed in the fame manner 

 to run a horizontal line or two above that at the fide of the 

 wing-tranfom ; fay, one at the upper fide of the wing- 

 tranfom at the middle line ; then run the main half-breadth 

 line in the half-breadth plan, fig. 9 ; then, where the laft 

 horizontal line artd main height of breadth line interfeft the 

 aft-fide of the rabbet a; in the (heer-plan, _/!r^. 7, fquare 

 them down to the half-breadth plan,^^. 9, and take their 

 diilances from the middle line ni the half-breadth plan,_/?f. 9, 

 to where they interfeft the horizontal line 6, and the main 

 hilf-breadth line, and let them oft from the middle line on 

 their correfponding horizontal lines, in the body-plan, 

 fig. 8 ; then by continuing the curve, a, upwards throiigh 

 thefe fpots, the horizontal view of the tuck will be con- 

 tinued up to the height of breadth. 



Now, where the horizontal view of the tuck in the body- 

 plan a, fig. 8, interfefts the beardmg-lme b, take that height, 

 and transfer it to the llieer-plan, fig. 7, llriking th^rc the 

 horizontal line S, which reprefents the featingof the tuck; 

 then take the ditlance from the feating of the tuck, in the 

 (lieer-plan, ^T. 7, on the rake, (in the direftion of the rab- 

 bet of the poft (7, ) to the refpeftive horizontal lines and height 

 of breadth, and fet them up the middle line, from the hori- 

 zontal line S, at the feating of the tuck, in the body-plan, 

 fig. 8 ; ftriking a horizontal line to the rake, at every 

 height, as (hewn by the fine-ticked lines ; then, where the 

 horizontal view of the tuck, a, interfefts the horizontal 

 lines firft ilruck, carry it up parallel to the middle line, to 

 their correfponding horizontal lines on the rake ; which will 

 give the fpots through which the fine-licked curve is to 

 pafs, that will reprefent the proper (hape of the tuck, 

 agreeably to the rake, as c ; and the line to which the 

 fafliion-piece mould muft be made. 



The bevellingi for the fafhion-piece may ne.xt be taken, 

 by proceeding as follows. The aft-fide of the rabbet of 

 the poft a, in the fheer-plafi, Z'^. 7, reprefents the aft-fide 

 of the fafhion-piece of the tuck ; therefore, take the fiding 

 of the fafhion-piece, and fet it off afore the rabbet, and 

 fquare thereto ; then, by flriking a parallel line to the aft- 

 fide a, the fore-fide of the luck b will alfo be reprefented ; 

 next, from the feating of the tuck S, on the aft-fide, fquare 

 the hne C from the rabbet to the fore-fide ; and from its in- 

 terfeftion at c, take the heights of the horizontal lines up 

 ttie fore-fide, and fet them up on the middle hne from the 

 horizontal hne S, at the feating of the tuck, in the body, 

 plan, _/^. 8 ; ftrike horizontal Imes for the fore-fide of the 

 fafhion-piece, as diftinguifhed by the long-ticked lines ; 

 tlien, where the fore-fide of the fafhion-piece b, in the fheer- 

 plan, fig. 7, interfefts the horizontal lines and height of 

 breadth, fquare it down to their correfponding horizontal 

 line and main half-breadth, in the half-breadth plan, _yff . 9 ; 

 at which interfeftions take the diftances fquare to the middle 

 line, and fet them off from the middle line on their corre- 

 fponding horizontal lines, for the fore-fide of the fafhion- 

 piece, in the body-plan, fig. 9. Continue the fore-fide of 

 the fafhion-piece down to the bearding-line d, as you fee 

 ticked in the (heer-plan,_/^. 7 ; then take the diftance from 

 the interfeftions of the fquared hne at the feating c, down 

 the fore-fide of the fafhion-piece to the horizontal line i, 

 and where it interfefts the bearding-line d, and fet it off in the 

 body-plan, ^^. 8. Below the horizontal line S, at the feating 

 of the tuck down the bearding-line, ftrike a horizontal line 

 for No. I , and proceed a$ before direfted to obtain the half- 

 breadth
