Scuba diving is a sport that carries inherent risks and PADI, the world's largest scuba diving organisation offers a comprehensive range of courses to give people the skills and qualifications to dive safely. Ultimate responsibility for operating Scubacraft is with the pilot and they will have to be suitably trained with an official Scubacraft qualification.
Scubacraft is operated by a single person both above and below the water surface. On the surface, the combustion engine is used for power and directional control through a steering wheel and throttle arrangement. In order to submerge, the main engine shuts down and seals airtight. Occupants then fit scuba equipment before the craft sinks down into the water where electric thrusters provide the power and hydrofins control the direction.
In normal operation Scubacraft is designed to have slight positive buoyancy at all times, submerging under power using the thrusters. If at any time the craft loses power it will slowly float back to the surface in a controlled manner. If so required, Scubacraft will be able to lose its positive buoyancy in a special 'park' mode, thus allowing occupants to depart from the craft and perhaps swim off to explore inside a shipwreck before returning to Scubacraft.
Scubacraft features a system of limiting the maximum dive depth to suit specific market demands. Scubacraft has emergency backup systems that ensure any system issues will result in the craft rising safely back to the surface. Even with total failure of the main buoyancy system, Scubacraft can snorkel its main engine at the surface and rise up onto the plane under power.
More advanced safety features include an automatic depth control (ADC) system that assists the operator in maintaining depth, controlling ascent and descent. VHF radio, underwater communications, lights and GPS are accessories that further enhance safety and performance in operation.
Scubacraft also features an integrated SMB (Surface Marker Buoy) system that indicates its presence underwater to all surface craft and incorporates an EPIRB (Emergency Position Indicating Radio Beacon) transmitter.
Scubacraft will meet international classification and certification requirements, dependent on market and application.
