SHIP BUILDING. 
thus set off 11 inches at the head, and con- 
tinue it parallel to the middle line, as low 
down as the deck transom, which is 2 feet 
2 inches below the upper side of the wing 
ti'ansom ; from thence it is to taper, with a 
straight line, to 7 inches on the npper side 
of the keel. Then the half thickness of the 
post may be taken at each water line, in the 
body plan, and set np from the middle 
line, in the half breadth plan to its corre- 
sponding ending, as squared down, from the 
sheer plan, where the water lines intersect 
the aft-side of the rabbit on the stern post; 
then, with a radius of 4 inches, sweep an 
arch within the half thickness of the post, 
on tlie half breadth plan, and the water 
line ends, intersecting the back of the arch, 
and a line squared out from the back of the 
water line to cut the half siding of the post, 
would show the thickness of the bottom 
plank in that direction. Proceed to com- 
plete the fore part of the upper water line, 
with a 35 feet 6 inches radius, and ending 
of it similar as the main half breadth was ; 
and, for the centre of the radius, draw an 
horizontal line at 11 feet 6 inches, under the 
middle line of the half breadth plan, with 
the above radius extended from the half 
breadth, or spot, given at timber S gives the 
centre, where it cuts the line last drawn ; 
then sweep an arch from S, to the rabbit, 
will complete the upper water line. 
Proceed to set off the several half 
breadths and endings of the fourth water 
line as before ; set up at S, 16 feet 8 inches ; 
at 0, 21 feet ; at K, 22 feet 5 inches; at F, 
22 feet lOt inches ; at 0, 23 feet ; at 6, 22 
feet lit inches ; at 12, 22 feet 10 inches ; at 
18, 22 feet 2 inches; at 24, 20 feet 8 inches; 
at 30, 16 feet 8 inches ; and at 36, 2 feet 11 
inches. To sweep the fore part draw a 
line under the middle line, in the half 
breadth plan, and parallel to it, at 21 feet 9 
inches ; then with a radius of 47 feet, from 
the half breadth at S, sweep in the fore 
part to the rabbit, as the paper on which 
the draught is drawn will not extend so 
low as this ; in this case of sweeping in the 
fore part of half breadth lines an additional 
sheet is placed underneath for this purpose. 
Ending of the water lines being all the 
same abaft, refer to the ending of the upper 
water line. 
Proceed to set off the several half breadths 
and endings of the third water line ; at S, 12 
feet 4inches ; at 0, 15 feet 8 inches ; at K, 
20 feet 3 inches ; at F, 21 feet ; at 0, 21 feet 
5 inches ; at 6, 21 feet 4^ inches ; at 12, 21 
feet 1 inch ; at 18, 20 feet 3 inches ; at 24, 
18 feet; at 30, 12 feet ; and at 36, 1 foot S 
inches. We must here remark, that to 
complete this line forward with an arch, 
the radius would be too long for practice, it 
must therefore be finished by a mould or 
thin batten. 
Proceed to set off the several half breadths 
and endings of the second water line. Setup 
at S, 7 feet 3 inches; at 0,13 feet 6 inches ; 
at K, 17 feet 2 inches; at F, 18 feet 11 
inches ; at 0, 19 feet 3 inches ; at 6, 19 feet 
21 inches; at 12, 18 feet 11 inclies;at 18,17 
feet 8 inches; at 24, 14 feet 2 inches ; at 30, 
6 feet 2 inches ; and at 36, 8 inches ; draw 
it as the last. 
Lastly, for the first or lower water line : 
set up at S, 3 feet; at O, 8 feet ; at K, 12 feet 
6 inches ; at F, 15 feet 3 inches ; at 0,16 feet 
2 inches ; at 6, 16 feet 1 inch; at 12, 15 feet 
3 inches ; at 18, 13 feet 0i inch ; at 24, 7 feet j 
at 30, 2 feet 1 inch ; and at 36, 4 inches. 
Now all the water lines being drawn, in 
the half breadth plan, and their delicacy of 
shape, if we may so term it, well examined, 
we may proceed to show whether they will 
likewise make fair timbers in the body plan ; 
thus transfer the several half breadths of the 
water lines, as taken at 0, and set them off 
from the middle line, on their corresponding 
water lines, in the fore body plan, which will 
be found to answer with the shape of 0, 
already drawn ; then proceed in the same 
manner with the other timbers before 0, 
drawing curves through the several half 
breadths, and ending them at the’ keel to 
the inside of the rabbit, but as timber S, 
comes upon tlie stem in tlie sheer plan, the 
keeling will also come on the stem, in the 
body plan, therefore its height must be 
taken above the line, at the upper edge of 
the rabbit, as continued before the stem, to 
where timber S intersects the fore side of 
the rabbit on the stem, and transfer that 
height to the fore body plan, to intersect 
the half thickness of the stem above the 
base line, or upper edge of the rabbit ; in 
midships then, with a radius of 4 inches, 
sw^p an arch from that height within the 
half thickness of the stem, then a line drawn 
through tlie several half breadths of S, and 
ending over the back of the arch, at the 
keeling timber, S, will be drawn; and to 
complete the keel, draw a square line 
from tiie back of the timber to intersect 
the height of the keeling at the half thick- 
ness of the stem, and the timber S wilt be 
complete below' the breadth. Thus, having 
the perpendicular fore and aft appearance 
of the several timbers in the fore body, they
