Nothing, so far, had come from English writers. “The only English
treatise on shipbuilding that can lay any claim to a scientific
character was published by Mungo Murray in 1754; and he, though his
conduct was irreproachable, lived and died a working shipwright in
Deptford dockyard.”[22] But indifference was at last giving place to
interest. Inspired by the formation of the Society of Arts in 1753
(which Society was itself inspired by the recognition, on the part of
the founder, of the value of prizes and rewards in improving our breed
of racehorses) a London bookseller named Sewell succeeded in 1791 in
forming a Society for the Improvement of Naval Architecture. “Impressed
with the many grave complaints which reached him as to the inferiority
of our warships as compared with those of France and Spain,” he gained
the interest of Lord Barham and other influential men. A meeting was
held at which it was decided, as something of a novelty, that the
theory and art of shipbuilding were subjects of national importance;
that a radical deficiency in knowledge of the same existed; and that
the most effective remedy was a focussing of the wisdom of the country
on this matter by the institution of the above Society.[23]
For a time the society flourished. A learned paper by Atwood before the
Royal Society, on the stability of a rolling ship, proved that this
country was not wholly destitute of mathematical talent. An interesting
series of experiments was carried out for it by Colonel Beaufoy, a
devoted student who had made his first experiments on water resistance
before he was fifteen years old. It appears that his attention was
first drawn to the subject by hearing an eminent mathematician state
one evening that a cone drawn through water base foremost experienced
less resistance than with its apex foremost; and it was said that
sailors always took a mast in tow by the heel. The paradox excited
young Beaufoy’s curiosity. Before bedtime, with the assistance of a
neighbouring turner, he was making experiments in one of the coolers in
his father’s brew-house, a large bunch of counting-house keys being put
into requisition as a motive power. Though the society was dissolved in
1799 Beaufoy continued to pursue this subject with unabated zeal until
his death. In one direction, especially, he did good work. Attracted by
the frequency with which North Sea fishing vessels, fitted with wells
for carrying the fish, foundered at sea, he showed experimentally the
loss of stability involved in carrying open tanks of water. He also
demonstrated to English builders by means of models that Bouguer’s
diagram of metacentric stability was of great practical value, even for
large angles of heel. “His experiments,” says Mr. Johns, “should take
an important place in the history of stability of ships.”
