Boat…check. Submarine…check. Scuba platform…check. Submarine , boat, and dive platform…check. The Scubacraft 3 and 6 are the newest ultimate watercraft. Price tag? Well, that is not important right now. What is important is that this is on Dr. M’s Christmas wishlist. The SC’s are advanced twin-tunnel composite hull and deliver on the surface a 50 mph top speed on an air cushion. All the hydrodynamic control is brought with a 4 stroke fuel injected engine and underwater with jet drive powered by a high performance pump. However, keep in mind this boat is a dive platform. You can ride it below the surface, baby! The SC have intuitive dive controls, multiple dive capability, a stable submergence procedure, onboard GPS and dive computer, and onboard air supply with backup. And the coolest feature? VHF radio and and underwater comms. The 6 person SC6 has a range of 150 miles and provides 90 minutes of run time on the 4x24V lithium maganese batteries. How deep can you go? 50 meters with an underwater speed of 3 knots.
