摘要： Water rescue of an individual whether they be a man overboard (MOB) from a boat or someone close to shore requiring a water rescue by shore lifeguards, can easily become a dangerous and life-threatening situation within a few seconds.
The current invention offers a Compact Powered Rescue Apparatus (CPRA), a lightweight and compact powered watercraft that can be deployed from a moving boat in just seconds thanks to an innovative CO2 inflation system. CPRA can be stowed on-board a vessel and automatically inflated in just seconds much like the compulsory life-raft or pre-inflated and ready to deploy immediately from shoreline lifeguard stations.
CPRA is a powered watercraft based on U.S. Pat. No. 5,643,029 Motorized Surf Boots (Powered Waterskis), a recreational watercraft. However, in this case the craft is made inflatable, configured with a portable stretcher for water search-and-rescue operations, and driven by battery powered electric marine thrusters.

摘要： The invention relates to water ski (1) having a buoyant ski body (2), to which, in addition to a binding (3), a propelling drive is assigned, which comprises a rotary drive unit with a rotary drive (4) and a screw drive which can be driven thereby, and having a control device (6) for presetting a drive power. In order to create advantageous drive conditions, it is proposed that the water skis (1) of a pair of water skis each comprise a rotary drive unit with at least one drive sensor (7) each, an associated energy storage device and a communication device, which adjusts the rotary drives (4) of both water skis (1) as a function of drive sensor data and preset data of the control device (6).
