The Goubet submarine torpedo boat
is Of iron, IS feet inches long, feet 3
inches wide, and , feet 1Ol5 inches deep,
including the lookout dome.
The weight of the boat, with its water
reservoirs empty and without the crews
is 4,19G pounds (l,45O kilograms), and its
displacement when submerged is 1856
pounds in sea water (2,S0O liters). Its
buOyancy is, therefore, $50 pounds, and
the boat Is submerged by the weight of
the crqw and the water admitted to the
reservoir.
Each man requires about 400 liter.

To provide for this Il reservoir contains
air at pressure of fifty atmospheres,
in sufficient quantity to last the crew of
two men for ten hours. The carbonic
acid and other acids are absorbed by
other chemicals, and an air pump expels
the foul air.

There is TO rudder, but a universal
joint in the screw shaft permits the
screw to move through an arc of so de
grees on each side.
In submarine boats il is essential that
the trim should be very exact, as other
wise the motive power might cause the
boat to jump out of water or dive to un
safe depths. To maintain the trim III
the GoUbet boat there is a water tank at
each end of the boat connected with
double acting pump, which draws and
delivers i'll opposite directions, accord
ing to tho direction or opposite motion
of its shaft. This shaft ends i'll crown
wheel, which may gear with either of two
wheels on a shaft at right angles to the
first, and revolving constantly III tho
same direction. As long as the boat re-
mains with its axis horizontal, the pump
is mOtionless, but on any change of the
axis n pendulum throws the pump into
gear with one of the two wheels on the
second shaft and water is pumped from
the lower to the higher tank, bringing
the boat to Il level axis.
The torpedo is carried outside the boat

trolled from the inside. On arriving
under the enemy the torpedo is released
and rises by its reserve of buoyancy un-
til il catches on the vessels bottom by
spikes, with which its upper surface is
provided. The torpedo boat then with
draws, maintaining its connection with
the torpedo by upreeling wire. When
the boat is at a safe distance the torpedo
is exploded.
The boat is also provided with small
torpedo, which when released, rises to

its flame, calls attention to the boat and

In case the motor breaks down there
is an arrangement for working two oars,
which habitually trail alongside These
oars, fold longitudinally. When in use
they open at the stroke and close at the

1t is stated 800 of these boats were ord
erd for Russia in 1881, and that fifty
were delivered 1888. The early form of
the boat was driven by manual power.
