This may be a prototype of the M80 Stileto which is being developed here along these docks. The length (88 feet) is almost exactly the same. Perhaps wihout the carbon fiber shell. "Looking like a cross between the Batmobile and a hovercraft, the M80 stiletto is composed of a carbon fiber composite that is both very light and strong. The 88-foot-long vessel, designed by San Diego’s M Ship Co., also features the company’s patented M-shaped hull, which provides for a fast and stable platform for mounting electronic surveillance equipment or weapons or for conducting special operations."
