DIMENSIONS OF THE CHALLENGER
FULL DETAILS OF SHAMROCK IT'S MEAS
UREMENTs NOW MADE PUBLIC.

The correct measurements of the Shamrock's
hull are here published for the first time in this
city. Among the other dimensions now made pub
lie two have been published here. The others are
new. The most important item is the boats beam.
concerning which no one seems to have devoted
than hint, and that a wrong one. The
chaengers width is exactly the same, to an inch,
that of the last victor the Columbia-namely,
"a feet. Her draught of water is about foot
inches less-namely, 10 feet. In over all length
the new Shamrock is 1s7 feet and not 1874 as has
been published. Her waterIine is intended to be
close to the ninety foot limit
Above water she is plated with aluminium and
below the surface the plating is of manganese
bronze. All the pla ting. both above and below have
the contact edges tapping each other. This gives
much extra strength the hull. but has been
avoided by the designers of the Constitution and
the independence. who have believed in making
their huils as smooth glass all over. The thin
nickel plating which is in the construction of
the decks is covered with light planking of pine
over which there is painted canvas to make all
watertight
The mast is stepped far out from the forward
part OF the Keel, being closer than in the other
ocats TO the stem-head, beyond which the horn
extends 20 feet out from the CANNON iron The
