Captain Washington thus describes Beeching's model sent to the
Exhibition: 'It may be seen from the model of that boat, that from her
form she would both pull and sail well in all weathers; would have
great stability, and be a good sea-boat. She has moderately small
internal capacity under the level of the thwarts for holding water,
and ample means for freeing herself readily of any water that might be
shipped; she is ballasted by means of water admitted into a tank or
well at the bottom after she is afloat; and by means of that ballast
and raised air-cases at the extremities, she would right herself in
the event of being upset. It will thus be seen, that this model
combines most of the qualities required in a life-boat; and the boat
which has since been built after it, and is now stationed at Ramsgate,
is said to answer her purpose admirably.'
M. Lahure, of Havre, sent a full-sized boat of _iron_; and Mr Francis,
of New York, also sent a model life-boat of corrugated galvanised
iron. Captain Washington thinks, that if metal is used at all, it
should be copper in preference to any other. For our own part, we can
only say, that we have helped to build boats, though not life-boats,
and we have helped likewise to man boats, but we should like to have
good sound timber beneath our feet in preference to any metal
whatever; and we should prefer cork for the floating substance to
air-tight cases, or copper tubing, or any of the other contrivances
that have been adopted to give buoyancy to a swamped boat. Air-cases
are very liable to leak, or may be stove in by the sea, or be crushed
by coming in contact with the wreck or rocks, but cork can never be
injured. And as to metal air-cases, it was found on opening the sides
of a life-boat at Woolwich Dockyard, that her copper tubes, supposed
to be air-tight, were corroded into holes; for copper will corrode
when in contact with sea-water, especially when alternately wet or
dry, as is the case in life-boats.
We cannot here follow Captain Washington through his critical and
technical details, but we think it right to express our strong
suspicion, that the much-lauded _self-righting_ power of certain new
life-boats is obtained only at the cost of greater liability to upset.
Doubtless a boat can be made to right herself after a capsize, but
this really seems to us something like locking the stable-door when
the steed is stolen; for even if she rights the very instant after
upsetti
