and the hull weighs las pounds. It IL fitted
with q 80 horsepower moto and with this
installed 1t weighs less than 500 pounds.
The model is similar to the French model
and has one jog In the bottom, The total
depth o. the boats sides 10 NJ inches and
the jog is Al inches deep. The engine is
installed forward Of the jog, or tooth, asst is
sometimes called. and the shaft goes out
through the middle nso TIL operator
will sit in the stern Of the boat, his-weight
bringing the hull to its proper trim. There
are two rudders. one on each side OF the
stern transom. This arrangement brings the
rudders outside the current created by the
propeller and reduces friction.
The hull lie built Of pine. The only piece
OF hardwood used is the thin piece OF oak
oiled silk. The floor and side frames are
Of pine, one-half inch at the bottom and
tapering to one-quarter inch at the top.
They are spaced 8 inches, The bottom Is
three-quarter inch thick and the sides one
quarter inch. The scoop shaped bow IL
planked in two thicknesses and the total
thickness is but three-eighthR inch. There
are two fore and aft %stringers or trusses
Of three-quarter inch pine 10 stifen the hull.
and several cross bulkheads all cut out in
ovals to lessen the weight. This boat Ia
expected TO make thirty miles an hour.
Lawley has built Il h~ydroplane designed
by Fred Lawley, which IL IS feet long and
will weigh a little more than q hundred
pounds. This will he fitted with q "a horse
power motor and more than thirty miles

A b. Raymond has had one built by the
Bath Construction Company Arthur Bin
ney has designed two Of these boats, which
are to be 20 feet long and 5 feet wide. Each
will be equipped with a 81 horsepower
motor and thirty miles an hour is expected.
At Lawley's another boat Ia building which
Is IA feet long and Z feet wide, for use oil
Silver Lake near Plymouth. This boat
will have a z horsepower motor.
An IS foot gliding boat to be named
Skiddoo has been designed by c.. u. Mower.
The Rudder OF this month prints plans
and a description Of this boat as follows;
The length il IL feet and the design
has been worked out on the three plane
system. which is believed to give better
results in a craft OF this length. The success
of a craft of this type depends to the greatest
extent on reducing the weight to the smallest
possible amount. so whenever an ounce Of
weight can he saved in the construction Of
the hull it must he done and the engine
equipment must he the very ltRhtest outft

THE design shows a hull is feet over all
with 4 feet extreme beam and with sides
parallel to within a short distance OF the
bow. where they round in slightly. h
bottom shows two joys or notches 8 inches
deep and 5 feet Q inches in length, with an

TO give the least resistance. The sides Of
the boats are vertical and the bottom abso-
lutely fiat athwartship.
The steering wheel and controlling de-
vices are placed on the afterside OF the mid
ship bulkhead and a seat placed on slides
80 that the operator can adjust the trim
and balance of the boat by moving his
weight forward and aft.
THE gasolene supply tank must be
placed aft. and it may be above or below the
deck, as preferred. Two rudders must DO
fitted with a cross bar connecting with two
tillers. A hood is thrown over the engine
cockpit, but this is not essential, as 1t must
suitable only for use in smooth water, and
the spray is thrown off on either side clear
OF the boat. At the water line shown the
boat has a displacement Of LOO pounds.
and on this displacement with an engine
developing 5-S0horse-power the boatshould
have a speed Of thirty miles an hour under
favorable conditional
