BALLAST AND LADING.--A ship's behavior, as the phrase is, depends as
much upon the manner in which she is loaded and ballasted, as upon her
model. It is said that a vessel may be prevented from rolling heavily,
if, when the ballast is iron, it is stowed up to the floor-heads;
because this will bring the ship back, after she has inclined, with
less violence, and will act upon a point but little distant from the
centre of gravity, and not interfere with her stiff carrying of sail.
The cargo should be stowed with the weightier materials as near as
possible to the centre of gravity, and high or low, according to the
build of the vessel. If the vessel is full and low built, the heavy
articles should be stowed high up, that the centre of gravity may be
raised and the vessel kept from rolling too much, and from being too
laborsome. But a narrow, high-built vessel should have the heavy
articles stowed low and near the keelson, which will tend to keep her
from being crank, and enable her to carry sail to more advantage.
CHAPTER II.
CUTTING AND FITTING STANDING RIGGING.
Measuring and cutting lower rigging and lower fore-and-aft stays.
Fitting the same. Measuring, cutting, and fitting topmast rigging,
stays, and backstays. Jib, topgallant, and royal stays. Rattling down
rigging. Cutting and fitting lifts, foot-ropes, brace-block straps, and
pennants. Breast-backstays.
CUTTING LOWER RIGGING.--Draw a line from the side of the partners
abreast of the mast, on the deck, parallel to the channels, and to
extend as far aft as they do. On this line mark the places of each
dead-eye, corresponding to their places against the channels. Send a
line up to the mast-head, and fasten it to the mast by a nail above the
bibbs, in a range with the centre of the mast, and opposite to the side
the channel line is drawn upon. Then take the bight of the line around
the forward part of the mast, and fasten it to the mast by a nail,
opposite the first nail, so that the part between the nails will be
half the circumference of the mast-head; then take the line down to the
mark on the channel line for the forward dead-eye, and mark it as
before; and so on, until you have got the distance between the mast and
each mark on the channel line. Now cast off the line from the
mast-head, and the distance between the end of the line and each mark
will give you the length of each shroud from the lower part of the
mast-head. And, to make an allowance for one pair of shrouds overlaying
another, you may increase the length of the pair put on second, that
is, the larboard forward ones, by twice the diameter of the rigging;
the third pair by four times; and so on.
The size of the lower rigging should be as much as eight and a half
inches for vessels of seven or eight hundred tons, and from seven and a
half to eight for smaller vessels, over three hundred tons.
