nj Russia. Guards are everywhere; at
the gate stand several; at different parts
of the yards are several more, and an
army guards the portals of the shop
where Morgan's new racing yacht is be-
ing built.
But in spite of all this, people get in
and bring out the information they wish.
And as it happens. this is the informa-
ton wanted by the public.
When the prospects for an international
yacht race for the Americas cup became
a fact, and the probability of building a
new craft 10 represent the New York
Yacht Club formed the principal topic OF
conversation among Yachtsmen, Designer
Nat Herreshom made the statement that'
should he he commissioned 10 build the.
new boat, he was prepared TO guarantee
an increase of speed over the Defender
OF 1925 of six minutes over thlrty-mlle
course. From reliable data that have
been received from yachtsmen who have
kept in close touch with G. Oliver Iselin
and others who have had access TO the
yard where the new yacht is being built
II can he stated that when the big cup
defender is tuned UP 70 concert pitch she
VIII make good the prophecy of the noted
designer.
Nearly three months ago a well-known
naval architect said that he thought Her
reshoh would probably take the lines Of
the Defender as a basis upon which to
be evolved from her model by the simple
process Of lowering and augmenting the
amount of lead in her keel, thereby in
creas3ng the draught of the vessel and
giving her a greater amount of stability.
This Improvement alone would give
great sai-carrying capacity, and 1t will
be remembered that it was by such i'm
provements that greater speed was OBJ
tanned in the Defender when compared
to the Nigiiant and Colonla.
Trustworthy information has been
CLEANED that Herreshoff has worked
mainly on these lines, as a comparison
with the principal dimensions of the De-
fender will show:
The overall length of the new boat will
be Isl feet I inches or feet I INCHES
longer than the champion of 1895. She
will also have eleven and a half inches
more beam, one foot greater draught and
nearly 1000 more square feet of duck in
her working sails. She will have trifle
more displacement than the old Defender.
Her complete sail spread will not be far
from 70 500 square feet.
Jobin bronze and niCkeled steel are the
sole materials used in the construction Of
the hull of the new defender, the latter
being used for the topsides, with the I'M
derbody Of bronze. The experiment of
the Defender mas proved that aluminium
is not the proper thing for tOpsides of a
big sailing yacht 1t is compelled to
bear a great deal Of strain and becomes
weakened through the action of salt
water and air and is especially bad when
used in conjunction with another metal
that will generate galvanic action. For
this reason aluminium has been discarded
IN the construction of the new boat and
through the extra weight of the steel as
compared TO the lighter metal her hull
will be somewhat heavier than that Of
the Defender.
T0b1n bronze, which will sheathe the
Un6erbody or wetted surface, is the light
est and smoothest that the manufacturers
have as vet made. and 1t will be riveted
t1 the frames in the same manner as on
the older boat The bronze will be put
on in five strakes. seven-fortieths of an
iuch thick. and the steel topsides will be
worked on in two strakes, each One-quar-
ter-nf an inch thick. She will not have
as much freebOard as the Defender, but
will have a crown to her deck of ten
inches.

and, coupled with the lowering of the

ity to carry additional sail.

Of the run have been refined trfe but
do not differ materially from those Of
the Defender Nor is there any marked
difference in the breadth of the lead keels
Of the two boats. The extreme width
o
Defender, was twenty inches. which
has been reduced to twenty-one inches in
the new craft. and the bulb of both is
about the same, nearly three feet. The
new boats lead casting is nearly two feet
deeper than that Of the old champion and
weighs in the vicinity of ninety-five tons,
or about ten tons more than the De-.
tenders.
In displacement. Commodore Morgan's
boat viii be between six and seven tons
heavier than the Defender, which, with
the new design and various other i'm
provements, Will practically be that much
weight as ballast. A new feature is a
statement that the new defender will be
equipped with steel mast as well as
other spars, and the Defender will also
have metal mast to replace the Oregon
pine stick that she carried in the races
Of 1895. The mast for the new boat will
be Of thin plates Of steel riveted to longi-
tudlhal braces ON the inside and will show
the same smooth, cylindrical surface as
did the steel boom and gait of the old
Defender. 1t Will be twenty-ore inches
in diameter at the deck. and will be a
great deal lighter and stronger than the
