Found in "Helicopter and VTO World, January-February 1961 issue, three designs for
hovercraft aimed at te commercial and military market. On http://worldhovercraft.org/insider/aug06_printable.htm
a prototype of the Aquagem (Aqua GEM) is shown and three more examples are mentioned.
but with the large rear propof the first vehicle differed considerably from the later designs,
which should be driven air ducted from the fans to guiding vanes.
A larger hovercraft, designated GEM-2 and actually built for the Marine Corps is mentioned, too.
It is said to have been powered by two 240 hp Ford engines driving six fans.
