Yet another affordable and very compelling new water vessel has reached market. With a price in the region of an expensive sports car, the appropriately named Dutch company Uboatworx has begun producing the first affordable recreational submarine (U-Boat). Uboatworx currently builds a single seat version known as the C-Quester I with a two-seater due in June. Both C-Questers have a top speed of 3.5 mph, are safe to a depth of 50 metres and offer a dive time of 150 minutes. At just over 9 feet long, 6 feet tall and wide and weighing 1.1 tons, the submarine is small enough to trailer to the nearest boat ramp or launch from a yacht. Entry is jet fighter style through a canopy, steering is via a joystick and both the seating position and the experience are apparently quite similar to flight, though getting a license is much cheaper and less time-consuming than a pilot’s license - a three day course and an exam being the only obstacles, apart from the UKP65,000 price tag (more for the two-seater). The cabin is pressurized, a filtration system removes spent air, oxygen is added to maintain air quality and all the safety boxes appear ticked, so the C-Quester appears an out-of-the-box winner at such an affordable price. Motive force is supplied by three electric motors – so it’s a genuine plug-in electric boat which just happens to be able to operate below the surface too.
