François-Alexandre Bertrand has designed and built an unusual surface-underwater vessel, which was named Platypus Swordfish.
Swordfish is a 12-meter tourist the tender (a small support vessel for cruising in shallow water and larger ships – approx. ed Techcult) for eight people. Its unique feature is that it allows passengers to travel both over water and under water.
The underwater module is sealed, the air in it is pumped pump. While the transparent cab can be opened in good weather and fully closed to dive.
Swordfish will be delivered in fully electric and hybrid versions. The electric version can accelerate to 40 knots (cruising speed is 18) and is 115 nautical miles on a single charge. The hybrid model at 10 knots faster, has a much greater power reserve – but as with electric Swordfish can swim under water in complete silence thanks to the electric motors.
It’s almost all information that the company Bertrand is ready to reveal at this stage. Swordfish production would start in 2021, and the debut of the ship shall take place at the Yacht show in Monaco. Interest in development was expressed by the customers from USA and Gulf countries.
