The Discovery 1000 from US SUBS is one of the coolest sea going vessels Iâ€™ve ever seen. Designed to be used as both a boat and as a submersible, itâ€™s made for launch and recovery from a superyacht (incase having your own helicopter to get from your boat to land just isnâ€™t cool enough), and is available in 2 to 10 person versions. Inside, the occupants are treated to luxurious leather seating, air conditioning, and an almost entirely unimpeded view of the undersea surroundings. On the surface, the sub behaves similar to a boat, and the whole thing is controlled via a digitally proportional joystick and animated graphic touch screen display. The boat/sub has a range of 56 nautical miles and can dive to a depth of 1000 ft for up to 28 hours, traveling at a speed of 2 knots. If I had one of these, Iâ€™d put a CD player in it so I could listen to the James Bond theme song at every possible moment.
