is 
do this a second upper boom is used, as shown; also a horse for 
the end of the sheet to travel on. By means of the clew outhaul, 
from the clew of the sail to the after end of this upper boom, the 
sail can not onlj' be rolled up in the ordinary manner, but the sheet 
lead can be perfectly adjusted, so as to get exactly the right pro- 
portion of strain on the leach and foot of the sail. . 
The sheet is spliced around a thimble travelmg on the horse, 
and is then rove forward through the single block on the upper 
boom, and down and aft througn a cheek sheeve on the fore end 
of the lower boom, and aft to the cockpit 
The clew outhaul is spliced to a rmg travelmg along the upper 
boom, and rove aft through a bullseye or block on the clew of the 
sail; then down through a sheeve in the bare end of the upper 
boom; forward and down through another cheek sheeve in either 
the upper or lower boom (but on the opposite side of the sheet 
lead), and aft to the cockpit, like the sheet. , , . , 
The roller line is fast to the drum of the roller, and led aft 
through a thimble seized on the lower boom near or on the goose- 
neck of the upper boom. , . , , , j r 
The spinnaker guys are endless, bemg fast to the fore end of the 
lower boom, where the wire tack is made fast;- then passing aft 
outside the shrouds and through two small eyes in the deck, one at 
each after corner of the coamings, returning to the end of the 
boom on the other side in the same manner. By this arrangement, 
when the fore tack is let go, and the sail hauled round as a spin- 
naker, the guy overhauls itself and leaves enough slack to belay 
on a jamb cleat on deck, but at once becomes taut when the 
boom is amidships and the tack hauled down again. 
A light pair of signal halliards should be rove through a small 
screweye in the top of the masthead, or through a truck; but the 
latter is very clumsy on a small boat with a stump masthead. 
These signal halliards are very useful for hauling the cover up the 
roller foresail, as it is laced or hooked on; as by this means a roller 
foresail can be kept clean and dry as easily as any other sail. 
The centerplate is lifted by means of a wire fast to the arm of 
the plate and rove through a large metal block on the mast thwart, 
and spliced around a double block, to which the standing part of 
the tackle is made fast, the other double block being shackled to 
a deckplate or eyebolt on the after end of the center case, a manila 
fall bemg rove through the two. 
The chief differences between the rigging of the No. 2 boat and 
that of No. 1 are that there are several extra parts, consequent on 
the greater strain and the extra sails of the larger boat. They are 
as follows: 
SAIL PLAN OF NO. 1 DESIGN. 
Standing Rigging. — One shroud a side from the hounds and one 
shroud a side from the masthead, through the arms of the cross- 
trees. These are set up with rigging screws to two separate 
shroud plates each side. 
One runner a side, from the four-eyed band, to which the peak 
halliard block and the roller foresail are attached. These runners 
are cut to reach to within an inch of the runner plate, and the end 
is shackled to a horizontal wire rope, stretched tightly between the 
runner plate and the after shroud plate, so that the shackle will 
travel freely fore^nd aft along the wire, out will not come right up 
to the runner plate. A small manila line spliced to the end of the 
runner and led through a bullseye on the runner plate serves to 
haul the runner aft, and consequently tightens it to any required 
tension with very little effort. The sketch fully explains the 
method of fitting. 
A topmast backstay should also be used for racing purposes, and 
would consist of a light steel wire cut to exactly reach the lower 
end of the runner when the latter is hauled aft. One of Blake's 
patent hooks is spliced into the end of the wire, also a manila 
line similar to that on the runner^ but of smaller size. 
The backstay is kept hooked into the eye of the runner when 
not in use, and is slacked oS with it by the one action. When, 
however, the backstay is required, it is unhooked from the runner 
and the manila line belayed on a strong cleat on the side of the 
coamings, as shown on the sail plan. This method is only suitable 
for a small craft, like the 24 linear rater; as, on a larger boat, 
sufficient strain could not be put on the backstay to set it up, in 
this case there would be a small snatch block on the backstay, 
and after taking the line under the cleat it would be taken over 
the snatch block and brought back to the cleat again and set up. 
For cruising purposes these backstays will not be required, as 
the large spinnaker and topsail would not be in use. 
Masthead. — The fittings of the masthead will, in addition to the 
hounds and bolsters used in No. 1 boat, consist of the following: 
A pair of American elm crosstrees, 4ft. wide and l%in. by lin. 
in section at the center. 
A four-eyed mast band resting on a 3-16in. shoulder at the point 
shown, and with a rivet through the masthead. This band carries 
the peak halliard block, runners and the roller foresail. 
There is a large sheeve at the masthead for the topsail halliards; 
also a small single block for the spinnaker halliards. Above this is 
the short pole and truck. 
A slightlv different method of fitting the masthead gear was 
shown in the chapter on spars, and eitlier of these may be used ; 
the sail plan shows the neater of the two, perhaps. 
Gaff.— This is slung at quite a different angle to that ot the 
smaller boat, and has a cheek sheeve for the topsail sheet; the 
peak halliards are of wire, similar to the throat halliards, and both 
of these are fitted as for the smaller boat. 
The only other differences between the gear of the two boats are 
that the larger boat is fitted with a bowsprit, and this has a short 
steel rod as a bobstay, set up to the bowsprit end with a nggmg 
screw, which is shackled to a small two-eyed band, to which the 
forestay is also set up.
