The New English Twin Shin.

Il
The London Standard of June 3 has
the following in reference to the new
twin ship just launched:
"One at least of tho many rival
schemes for transporting passengers
across the Channel in moderat., comfort
is likely to have fair trial. The Eng
lish Channel Steamship Company YES.
tcrlay launched their twin ship Casta-
liza from the slip of tho Thames Iron
Works and Ship-building Company, in
the presence of a very large assemblagc
of spectators. This vessel is built upon
what is known as Capt. Diccy's princi-
pie, but which, ns far as the general
scheme of double ship is concerned,
is no novelty whatever, although it has
never before been tried upon SO large 4
scale. We can perfectly remember q
steamer of about the size of the ordina-
ry Greenwich steamers upon exactly the
same principlc-namely, that OF a ship
cut in half long ways, the two halves
being connected by Il deck, and having
a waterway between them in which the
paddles worked. This steamer lay for
two OF three years at short distance
from shore off the Isle of Dogs. This
must have been eighteen years ago, and
the fact that she did so lie idle would
seem to prove that she was failure.
We are not arguing from this that
the Castalia will be failurc-far from
it, for VIC believe that she will prove a
great success the fact being that, in a
small craft there would be no advan-
tagc whatever in placing the two halves
OF IL vessel at some distance apart i'll
stead of uniting them, for even when so
widened thcshipwo,lld ENTHUSIASTICALLY
large to meet ordinary waves without
being influenced by them. In Il slipof
the size of tho Castalia, 900 feet long by
GO feet wide, the great tlesideratum Of
steadiness in anything like a,l ordinary
Channel sea, will, we think, he att;linci.
We 20 not think thatshe would be Il good
sea boat in IN Atlantic gale, for large
as she is, she is by no means sufficiently
so to dominate Atlantic waves; but in
anything but a very heavy gale she
ought i'll the Channel to be absolutely
steady, the fact, therefore,, that the
precursor of the Castalia may, perhaps
from want of engine power, have proved
failure Us river boat in, no way
initiates against the chance of success
Of the Castalia as q Channel steamer.
and no doubt Capt. Hely has produced
various improvements which will so far
to insure success. The deck, or, rather,
the network of iron which supports
the deck and connects the two compart-
ments, IS of immense strength, and had
we'll need to be so. The strain when q
great wave takes one compartment upon
the broatlside, lifting it up while the
other remains in the trough, will be
enormous, as the portion which rises
must rs 1t docs SO heel over the other
compartment to the same angle which
itself takes. This strain would, in
heavy ocean seas, be so great that it is
hardly likely that the principle can ever
be applied to great seagoing steamers
but in tile Channel the seas, even in
storms, IRE SO short and chopping that
vessel OF the size of the Castalia may
be expected to ride fairly over them
Large as she is, she can enter the har-
bors Of Dover and Calais at all times,
for she will draw only five fcctof water.
Both ends are alike, and provided with
ruddcrs, SO that she will not have to
turn in labor. The engines, nominally
of 260-horse power, constructed by
Messrs. j. & A. Blyth, work up to L.
5OO-horse power. Her outside lines are
clean and promise speed, and as the i'll
side works are perfectly straight, and
will offer 10 resistance whatever to her
passage through the water beyond that
of friction, there is no reason why she
should not DO nearly as fast as she
would have been had her halves been
placed together, instead of being scpa-
rated by all interval of twenty.six feet.
In this interval arc her paddles. They
arc not, Of course, rs yet in position in
tho Castalia herself, but, as shown in 1;
large model exhibited in one of the
Offices, they appear to be altogether
Extraordinarily small for the size of
