Only on rare occasional does one find a boat that would be significantly improved if run hard aground. Here is one example, however. Many large yachts have hot tubs onboard. This 16′ boat, however, is simply a floating hot tub with a diesel-powered boiler to keep the water hot, an electric motor for propulsion, a sound system and four coolers for beverages (of course.) I wonder where the PFDs are stored. Why this nautical accident-waiting-to-happen is in any way superior to a dock-side hot tub is not clear to me. With luck it would never leave the dock. Available at Hammacher Schlemmer for a price of $42,000.
