work. but the plating, or underbody, IL
heavy enough TO do good service In giving
additional rigidity.
Tho plating. like tho frames, Ia Of nickel
steel. Low down, where the weight Of the
hull is not against tho stability of the boat,
the plates are about q quater Of an inch
thick. but on the topsides they are so thin
that II Ia difiicult TO see how the counter
sunk rivets arc made to hold the frames
and plating OF the hull, which is carried
down to the bottom Of the draught. Lead
Is slung inside the bottom Of the fin, as in
Shamrock /. The decks are Of aluminium
sheets riveted to the deck beams.
The mast, gah and boom are Of hollow
steel The bowsprit Is of solid wood. The
lighter spars are Of hollow wood. Par
ticular care has been paid to that part OF
the hull which in Shamrock ii. gave way
and caused her dismasting. The bobstay
Is fixed by a new method. The pole mast
is slightly longer than that Of Shamrock ii.
1t has been laced In q novel manner, as
have also the san and boom. The yacht
Ia painted white, with a broad band Of
green at the wsterline, but this may not
prove to be her racing garb.
Perhaps the most interesting feature OF
Shamrock III. is that she is the first chal-
lenger to be designed with the help OF data
gained from the principles Of Robert Ed
mund Froude, superintendent Of the Ad-
miralty experiment works at Gosport, as
embodied by the experimental tank. She
is undoubtedly typical tank yacht.
Shamrock iii. will be steered with wheel
and not with tiller. as In the case Of pre-
vious challengers. She will outfit at Green
ock, and will be ready in ten days to enter
upon eail-stretchinR tests. In company with
Shamrock /. She will start on her trip
across the Atlantic about the middle of
June.
At the luncheon after the launching
Lord Provost Primrose proposed the health
Of Sir Thomas Upton and the success Of
the challenger. Speaking in the name Of
millions Of Sir Thomass well-wishers on
each side Of the Atlantic. he said their one
desire was that keen and tenacious strug
gle for supremacy would justify the old
proverb about luck on the third trial. They
all knew that IL would be formidable work
to beat the great Projections Of the Ameri-
can defenders Of the Cup and therefore they
could not fail to DO astonished at Sir
Thomas's colossal pluck and pertinacty.
It was a pleasant thought that the efforts
to wrest the sovereignty of the sea do not
provoke rancor hostility or unfriendly
rivalry. but bring the two great English
speaking people into praiseworthy rational
relationship.
Sir Thomas Upton, in reply, again ex-
pressed his belief in the success Of the chal-
lenger In the coming contest. But. he
said. whatever the result might be, there
was no doubt as to the welcome they would
receive from the American people. He
paid a high compliment to the builders.
designers. captain and crew OF the Sham
rock III. Everything, he said. justified
his most sanguine expectations.
Sir Thomas said the Americas Cup must
now be homesick They had fifty years
experience Of American yachts and Ameri-
can yachtsmen and knew that none more
than the Americans would cheer Shamrock
Ill. on to victory.
Sir Thomas then presented the Countess
OF Shaftesbury with beautiful souvenir,
Designer William Fife made a brief
speech In which he said his instructions
from Sir Thomas were: 90 on and do your
best
