Abstract: 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.

Abstract: In water or on land, an innovative Dual Retractable Handlebar System with adjustable damping, allows the rider of Motorized Surf Boots to transition from a kneeling, to squatting, to standing, or vice versa, in one smooth articulated motion while keeping a continued grip on the handles and throttles. Each handlebar of the pair is firmly connected to each boot (or board) safely behind the rider, with each handlebar extending around the outside of the rider to a comfortable and ergonomic position to grasp with each hand, providing the rider with the ability to impart body English on the left and right sides independently, in order to effectively steer his or her Motorized Surf Boots on water or on land. Additionally, the pair of Handlebars of the present invention can be quickly locked in the retracted (or down) position, or quickly released for deployment in a range of up positions.
