SHIP BUILDING. 
horizontal lines should be run from their 
heights in the body, to the half breadth 
plan and their knuckles, squared down 
thereon from the sheer plan, and at those 
places their half breadth transferred to the 
bodv plan. Thus we should find the half 
breadth at the lower counter knuckle 
14 feet 6 inches, and at the Upper counter 
knuckle 13 feet 5 inches ; then set off these 
half breadths on their corresponding hori- 
zontals from the middle line in the body 
plao, and by sweeping arches as at the 
wing transom, from the heights at the side 
and middle line, the round up of each 
counter would be represented ; then draw 
an horizontal line in the body plan, at the 
height where the top timber line curs the 
side stern timber in the sheer plan, and on 
it set off the half breadth of the top timber- 
line, which is 12 feet, as taken from the 
half breadth plan. Draw another horizon- 
tal line in the body plan, at the height of 
the top side, and on it set off 11 feet, its 
half breadth ; then draw a straight line 
from the knuckle at the upper counter and 
the two half breadths above it, and the up- 
per part of the timber will be formed, and 
from thence to the lower counter the same 
line may be continued, only having it to 
curve between the knuckles ; then to com- 
plete this timber between the knuckle at 
the lower counter and wing transom, three 
or more horizontal lines should be equally 
spaced and drawn across the body plan, 
then several Iralf breadths taken and set off 
the Iralf breadth plan, and curves drawn 
through them ; then when these horizontal 
lines intersect the side stern timber in the 
sheer pfan, they must be squared down to 
their corresponding lines drawn in the 
half breadth plan, and their several half 
breadths there t-aken and set off on their 
corresponding lines in the body plan ; then 
a curve passing through those spots from 
the knuckle of the lower counter to the 
wing transom at the side, completes the 
side timber in tlie body plan. 
Now to complete tiie half breadth plan 
and the main half breadth and top-timber 
line abaft, thus sqtiare down to the half 
breadth plan where the height of breadth, 
the top-timber line, cuts the side stern tim- 
ber in the sheer plan, and from thence 
transfer its height to the stern timber in the 
body plan, and there take its half breadth 
and set off from the middle line of the half 
breadth plan upon the line last squared, 
dowp which is its ending at the outside; 
from thence sweep a curve to the round aft 
of the stern at those places, and it is coiil-* 
plete. 
Now there only remains to complete the 
sheer plan, and the construction of the 
sheer draught or principal design will be 
completed ; and first set up the heights and 
lengths of all the decks thus, above the 
upper side of the gun deck already drawn, 
set up 7 feet 1 inch all forward aft, and 
draw a curve parallel thei'eto, which will 
represent the under side of the upper deck, 
and another curve, drawn 3 inches above, 
and parallel thereto, will represent the up- 
per side of the upper deck ; then above the 
Tipper side of the upper deck set iqr 6 feet 
7 inches at timber T, and forward to the 
beak bead ; tben draw a curve through 
these heights, parallel to the upper decks, 
and that will be the under side ot the fore- 
castle ; then draw another curve 3 inches 
parallel above it, and that will be the upper 
side. Again, set up at timber 6, above the 
upper side of the upper deck, 6 feet 
7 inches, and at the middle stern timber, 
6 feet 9 inches, and above those heights 
3 inches, drawing curves as before, the 
quarter deck will be represented. Set up, 
at timber 24, above the upper side of the 
quarter deck, 6 feet 5 inches, and at the 
midship stern timber 6 feet 7 inches, and 
above those heights 2^ inches, and the round 
house deck will be represented as well as 
the before mentioned at the middle line. 
The ports next claim our attention, but 
before they can be drawm, the decks at the 
side must be represented, and to do this 
correctly, the round np of the beam in raid- 
ships, or the longest, must be represented 
by the segment of a circle, as was lately 
observed for the round aft of the stern. 
Transfer the height of gun deck at 0 in 
the sheer, to the body plan, and then take 
the half breadth of the midship timber 
and set it off twice on some straight line, 
and in the middle set-up 6 inches, tlie 
round-up of the gun deck, at that place, 
dian ing an arch as before. 
Then for the round of the deck, or the 
deck at tlie side in the sheer plan, set down 
below the under side of the middle, as al- 
ready drawn at 0, 6 indies ; -and tor the 
other timbers observe the following method : 
transfer the height of tlie under side of the 
deck from the sheer, to its corresponding 
timber in the body plan, taking then its halt 
breadth and apply it from each side the 
middle to inscrsect the arch for the round- 
up of the beam at 0, drawing para’lei lines 
to each intersection, then the distance taken
