The research laboratory of the Saint-Petersburg State Marine Engineering University directed by laboratory head, PhD Vladimir Taradonov, has invented a `Dry Multi-Role Underwater Vehicle with Muscle Drive,` which will enable mankind`s long-dreamed-of hope to be realized and will offer Earth dwellers underwater spaces of some millions square kilometers. Preliminary analysis of the scientific-technological and other special literature, accomplished by the developers of the UV, allow one to stipulate that no serial `water-impenetrable` (`dry`) small underwater apparatuses with a muscular drive for mass use on resorts and in other possible areas of application are generally manufactured in the world at the moment. This is due to the fact that, with the traditionally mounted screw propulsors fixed on the underwater apparatuses, it would not be possible to ensure the necessary requirements for the speed of surface and underwater motion, because the capacity developed by one or two people would be limited, as it has been discussed above.
