Styled after a second world war British special forces project, the stunning Ortega Mk. 1C Personal Submarine affords the everyman–well, those who can afford it–the opportunity to go deeper for longer into the magical underwater world of our seas. A pair of 10KWh electric thrusters will propel up to three passengers up to depths of 310 feet at nine knots. Range is good for 80 nautical miles.
