![]() On the surface, the Seattle runs on diesel fuel, but once submerged, it switches over to battery power for a nice, quiet cruise. It can dive as far as 1,000 feet (300 meters) and can travel at a rate of about 14 knots underwater. Their 116-foot (35-meter) Seattle 1000 sub has five staterooms, generous common areas and looks much like a small yacht, save for the porthole windows that line the hull on both sides of the craft. ![]() Regardless of the depth of their subs, they remain pressurized at one atmosphere, leaving the comfy climate-controlled interiors feeling like you're above the surface at all times. Interiors can be selected from a catalog, or the prospective buyer can work with a designer for a 100 percent custom job. Submarines, Inc., has taken the luxuries of the fully-loaded yacht and integrated them into the personal submarine. The Seabreacher ranges in price from $48,000 to $68,000.Ī company called U.S. If you want to cruise the surface, you can crank that up to 35 to 40 miles per hour (56.3 to 64.3 kph). If you're wondering why it's called a "breacher" - just like the dolphin that inspired the design, this sub can actually leap entirely from the water at a maximum underwater speed of 20 miles per hour (32.2 kilometers per hour). You can only go about five feet (1.5 meters) down in a Seabreacher, but enthusiasts of this craft aren't interested in an ocean-exploring deep dive. There are two wings and a rear tail that resemble dolphin fins. The cockpit is where the head and mid-body of the dolphin would be, with a clear bubble surrounding the occupants for optimum viewing. The sub is shaped like, and operates much like, a dolphin, right down to its bottlenose design. ![]() Cross a jet ski with "Flipper" and you have the right idea. There's no mistaking a Seabreacher for a marine science tool this one is pure toy. For just south of $250,000 you can own a CQ-2, and say goodbye to your scuba gear. Maintaining a personal sub isn't easy or cheap, so C-Quester only sells their subs in markets where they have qualified mechanics available. Even so, the price tag comes with a mandatory four- to six-day course on how to safely operate the craft. The four 36-volt electric motors pack about 100 pounds (45.4 kilograms) of thrust, and the company claims that it's no more difficult to operate than a boat. Before the CQ-2, C-Quester was known for the single-seat model, and it now has plans to begin manufacturing a four-seat model. The CQ-2 can run up to two and half hours underwater and has an emergency air supply that will last about 36 hours. This means there are no decompression issues to worry about when diving and surfacing. It looks like a small, enclosed speed boat, with two clear bubbles on top for the operator and passenger to behold the wonders of the deep. The CQ-2 twin seater personal sub, manufactured by C-Quester, is a fully electric mini-sub that's capable of maintaining cabin pressure at one atmosphere. The same inventors came up with the idea of the torpedo at the same time, making the new submarine a very unique war tool. These subs were powered by petroleum or steam on the water's surface and used electric motors under water. Two rival inventors developed these two designs, which were purchased by the militaries of the United States, Russia and Japan. ![]() Skip ahead again to the 1890s, when the first modern-style subs were built. The United States military used The Turtle during the Revolutionary War, to middling success. The first military sub, The Turtle, was built in 1776 by David Bushnell and was powered by hand-cranked propellers. Of course, there were no engines at this point, so Drebbel and his 12 oarsmen hit the Thames River and submerged for about three hours. Fast forward about 50 years when a Dutch inventor named Cornelius van Drebbel built the first working submarine. He's basically saying that if you make the boat heavier than the weight of the displaced water, it will sink (purposely). It may be 1570s English, but the concept was undoubtedly that of a submarine. Any magnitude of body that is in the water, having always but one weight, may be made bigger or lesser, then it shall swimme when you would, and sink when you list." "It is possible to make a Ship or Boate that may goe under the water unto the bottome, and so to come up again at your pleasure. ![]()
