New Motors for the u. S. Gov
eminent

Inc 10ll0Wlng article is taken from I,
the Nautical Gazette of September
%, 1909:
"A new type of motor dory is be-
ing constructed for the U. S. govern
ment at the Charleston Navy Yard,
Boston, and for which quantity of
Bridgeport motors have been sup
piled for power.
''The boat was designed to meet
the requirements of a small tender
for torpedo boats and destroyers,
which cannot carry the heavy steam
launch commonly used in the navy.
The requirements call for boat able
to negotiate exceedingly rough wea-
ther, as the boats which carry these
tenders usually anchor in the outer
harbors where the water is rough.
A boat to be suitable for this work
must also be very roomy and of great
carrying capacity, so that designers
have found difficulty in bringing out
tender which would meet the re-
quirements satisfactorily. Mr.. R.
H. Robertson who has charge of the
boat department at the Charleston
Navy Yard is responsible for the de-
sign of this tender. He has had
broad experience in the building and
sailing of all types of boats, and de-
serves great credit for having met
the requirements so fully.
"The tender with its outfit complete,
weighs approximately 1,5OO lbs. 1t
has carrying capacity of from 8 to
10 persons, and together with being
admirably suited to the purpose for
which it is intended, its general lines
present a very pleasing appearance.
The length over all is 20 ft. 10 in.
The extreme beam is 5 ft. in, the
draft 20 in. The bottom of the hull
is of the fiat dory type about 80 in.
wide at the widest part. The hull is
carvel planked of 8 in. stock. The
curve of the overhanging stem is
more abrupt than usually in the reg
ular dory type, giving more fullness
at the water line forward, thereby
increasing the buoyancy and carry
ling capacity. This form of bow and
the method of planking employed
gives the boat more the appearance
of the regular round bottom launch
than that of the dory type. The
free board is greater than that of the
usual dory model, especially at the
bow, giving a very graceful sheer.
"The decks are finished bright in the
natural wood, as is also the coaming.
The seating arrangements consist of
transoms running from the forward
end of cockpit on each side full
length, to a seat across the stern of
cockpit. The athwartship seat is al
so provided just forward of the
motor.
"a steering wheel on the starbOard
coaming opposite the motor makes it
possible for the operator to attend
the motor and reversing lever, and
at the same time control the boat
without leaving his position. A
spray hood is provided which folds
down fore and aft, and which entirely
encloses the cockpit in bad weather.
THE boat is equipped with single
cylinder, 2-cycle Bridgeport motor,
having a cylinder bore of Al in, and
piston stroke of in., which showed
under government test over At h. p.
on the brake.
"The motor is regular stock model
and drives the boat at Z miles per
hour under ordinary conditions. This
motor has been found admirably
suited for this type of craft, on ac-
count of its simplicity, as well as
through the fact that it is capable OF
withstanding severe conditions under
) which these boats operate. Its gen.
, eral design is such that in case OF
Z necessity, repairs can be made by the
: operator with dispatch, as it is pos
y sible to remove not only the eXter
ior, but the interior working parts
