Submarines can generally be categorized by depth rating and number of passengers. Triton makes this clear with the 3300/6. As the name suggests, it can carry up to six humans down to depths of 3,300 feet, far deeper than the most daring SCUBA diver can go. The world's largest spherical acrylic pressure hull affords outstanding views from every seat while bright LED lights illuminate the depths. It has a joystick and touchscreen piloting system, a large hatch for easy entry and exit, and can be launched and recovered using a standard yacht tender lift.
