As explained, the principle in the
construction OF the new craft was Dor
rowed from the ideas of the inventor
In regard to aerial navigation.
The aero planes, instead of working
on air, operate in the denser medium
of water
At rest, the boat rests in the water
like any vessel; when under speed
the inclined planes, being forced
through the dense medium OF the wa
ter lift the hull clear, thus doing
away with almost all the resistance.
The greater the speed the higher the
craft rises.
There are three sets of planes on
each side, each set deeper under the
hull than the former. At from IL to
Ia miles an hour, the Gliding rises
until the topmost planes leave the
water. At 35 miles an hour all the
planes are driven upward but the
lower ones.
When Swimming along at more than
16 miles an hour the craft Is COM
pletely clear of the water. The effect
is that of being moved along on fiat
shoes or skees.
The model craft, which has attract
ed SO much notice, weighs 26SO
pounds. A boat of the same power
and strength, it is said, can be made
weighing 1900 pounds. Such boat
can bear a load of 1900 pounds.
With this as basis, it is estimated
that the craft can carry 60 pounds a
| horsepower unit at speed OF 60
miles an hour or even more.
| Another advantage of Mr.. Hewitt's
model is said to be the ease with
which 1t takes sharp curves at high
speed.
There is no loss of equilibrium, 1t is
claimed, but the stern skids just as
the rear wheels of an automobile slew
over wet asphalt when driven around
q sharp curve.
From the data he has obtained in
constructing the Gliding, Mr.. Hewitt
has worked out rules for the guidance
of constructors Of similar vessels.
The area of the planes should de-
crease with speed for economy, speed
and safety. They have lifting power
of about 300 pounds per square foot
at 80 miles an hour.
The limitation OF speed bias only
been in the propeller. With the pro
peller in use in the Gliding, SO miles
an hour is possible and is calculated
for.
With a propeller expressly design.
ed for a speed of 100 miles an hour,
all the limits to an incredible rate will
be eliminated, it is believed.
The craft will greatly improve In
speed, stability and commercial posi-
bilities with increased size, Mr.
Hewitt claims. The larger the craft
the better the principle will work, ac'
cording to his calculations.
AS the surface of stretch of water
is uneven, the hull is lifted out OF the
resistance caused; at sea, in the great
waves of storm, the larger the craft
the smoother it will glide over the
toughest seas.
Aside from the prospect of the use
of this discovery in peace projects are
the possibilities in warfare.
BY the absolute elimination of roll
ing and pitching, it will be possible
to use the large guns at high speed
with the same accuracy as when the
vessel is at rest.
Experts have shown that in naval
warfare guns cannot be accurately
aimed on vessels going at high
speed But on gliding" fitted OUT
as a cruiser, travelling at the rate Of
an express train, the ships battery
could work accurately, they believe
Such boat could dash by fort
raking it with it's heavy guns, but al
