On the powerboat side, it's a heavy-duty, 31-ft. surface-cruiser with an enclosed cabin. Powered by twin 440 hp inboard diesels for a total output of 880 hp, the Hyper-Sub has a maximum surface speed of 40 knots and a maximum surface range of 500 miles. In dive mode the Hyper-Sub can plunge up to 250 feet, and offers umbilical SCUBA support.
2. Yellow Submarine
I don't know how far you could go with this guy from the shore, but man, I would love to see it for myself. After all, they only cost a low price of…two million dollars? Well, I knew that this type of hobby wouldn't be cheap.
3. EGO Compact Semi Submarine
The clear view gives the user a terrific view of the aquatic life, which is perfect for those who want to see fish up close without getting wet. Best of all, the EGO is eco-friendly as it is mostly electric-powered. On a 6-10 hour charge, the user is able to get about four hours worth of cruising time. The EGO semi-submarine is made by a company called RAONHAJE, and the product's official website does not have a price. All I have to say is: “if you have to ask, then you can't afford it”.
4. Seabreacher X
The Seabreacher X can sustain high speed dives and then breach the surface, launching the entire vessel clear out of the water. The new fully vectored thrust system mimic the tail articulation of real aquatic animals like sharks and dolphins. The custom tuned exhaust system also gives the vessel a more throaty growl as it tears across the surface.
5. Deep Flight Super Falcon
It has a single rear-mounted propeller, looking much like an electric fan, drives the vessel, and a 48-volt lithium phosphate battery provides power. Its thick pressure hull is a carbon-epoxy mixture, and the two passengers aboard ride seated in cockpits fore and aft, observing their watery surroundings through thick Plexiglas canopies.
According to Hawkes, the craft “flies” just like a jet plane, with electric motors controlling for roll, pitch and yaw. It can fly downward at a maximum of 200 feet per minute, upward at twice that speed and keep flying for a maximum of five hours at 4 knots – about 4.6 mph. John McCosker, [California Academy of Sciences] chair of aquatic biology, said the agile submarine will enable him and his colleagues for the first time to follow along with the travels of “whales and dolphins and even super sharks – maybe even the mysterious giant squid.”
