Founder Francois Alexandre Bertrand and his team released the schematics which reveal a number of augmented features, including upsized twin hulls to improve surface navigation capacity.
Other notable additions to the 19-foot, four-person vessel include a built-in electric air compressor – or "hookak" – to supply oxygen to passengers when beneath the waves. Additionally, the final version’s weight has been reduced to 700 kg to ensure it can be transported in a 20-foot shipping container.
Several optional features have also been included, such as an underwater visualization system consisting of a waterproof display and surface camera, with 360-degree viewing angle giving passengers the ability to manoeuvre the craft while underwater.
Other customizable add-ons include a central platform (or sundeck), digital periscope, submarine lights, underwater cameras, GPS, Wi-Fi, and "Ocean Reef" mask submarine communication system.
The Platypus, which will be CE certified as a "standard boat", will be available from next year for prices starting from €50,000 (US$69,000). Platypus is accepting pre-orders from this month.
