The Jungle Yacht was created for and used by Italian explorer Commander Attilio Gatti and his wife, who both traveled extensively to the African Congo as a deluxe apartment “for his 1937-1940 (his 10th) and 1947 (his 11th) expeditions” and “equipped them quite lavishly.”
The expedition used two streamlined trailers designed by Count Alexis de Sakhnoffsky and using 1937 International Harvester D-35 chassis, and were 44 feet long and weighed 9 tons. The vehicles were built by the International Harvester company, who was evidently one of the sponsors of the expedition.
The trailers were pretty luxurious accommodations for camping out in the boonies of British East Africa. They were joined together in camp as a deluxe 5-room apartment on wheels, and served as headquarters while the expedition’s personnel sought out the secrets of the dim heart of Africa.
The camps were equipped with electricity and air conditioning and had a workshop, a photographic lab, and a ham radio station (Gatti was an enthusiastic ham radio operator). Electricity was supplied by a 110 volt generator mounted behind the cabs of the trucks. Each night a single wire 4500 volt electric fence was put up to dissuade the large specimens of the local wildlife from approaching the camp.
