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.
