Cowes, oil depuis plus de 20 deja Mr. Saunders
se consacrait a 1'etude et a la construction
de canots automobiles, hydravions monocoques et autres appareils d'aviation. Sous
son nouveau regime, la maison Saunders-Roe
—habituellement designee par l'abreviation

chantier toute une serie d'hydravions marins,
de construction similaire mais de dimensions
et de puissances differentes, comportant tous
une coque en duralumin et des ailes en bois.
Le plus petit est le " Cutty Sark " a quatre
places et deux moteurs " Hermes." Ensuite,
vient le " Windhover," appareil a six places,
puis le " Cloud " qui est capable de prendre
a son bord de 8 a 10 passagers. Chacun de
ces trois types peut s'amenager en appareil
amphibie et comporter differents groupes
moto-propulseurs, au choix.

A FTER severing his connection with the firm which bears his name, Sir
•** Alliott V. Roe, with his old friend and associate, Mr. John Lord, acquired
a controlling interest in another old-established British firm : S. E. Saunders,
of East Cowes, Isle of Wight. The new firm was renamed Saunders-Roe, Ltd.,
usually abbreviated into Saro, and a vigorous policy of development was at
once instituted, with Mr. Knowler as chief designer.
Mr. Saunders having been a designer and builder of motor boats for 50
years or more, and Sir Alliott Roe and Mr. Lord being believers in the flyingboat type of machine, it was natural that the firm should turn its attention to
this type of aircraft. At Olympia last year was exhibited the first Saro machine,
the little " Cutty Sark " with two Hermes engines. That machine was the
first of quite a little " family " of amphibian flying-boats, the third of which
appeared a few weeks ago, and is known as the " Windhover," while the
second member of the family made its appearance some time ago and is
called the " Flying Cloud."
In all three machines the constructional features are similar, and a description of one will, with minor modifications, apply to all three. First, however,
it should be pointed out that the three amphibian flying-boats mentioned cover
a range in size, power and carrying capacity calculated to meet the requirements of all but those desiring really large seagoing civil flying-boats. The
" Cutty Sark " is the smallest of the three, and carries pilot and .three passengers. The " Windhover " comes next as a six-seater, and the " Cloud "
last as an 8-10 seater.
Two main features of construction were decided upon from the outset in
planning the Saro amphibian flying-boats. They were to have wooden cantilever wings and light metal hulls, the wings and hulls to be built as complete
units so as to reduce maintenance costs to a minimum.
The Saro wing construction consists of two main spars of box section with
spruce flanges and three-ply walls, while the ribs are of three-ply. The entire
wing is covered with three-ply, and in the neighbourhood of the engines this is
made thick enough to walk on. This wing construction is simple, does not
