The Columbus 199 designed by Hydro Tec is an eco-conscious $40 million superyacht slated for completion in 2012. The sleek 199-ft. steel and aluminum superyacht was designed to respect the environment without losing its sexiness. The Columbus 199 can accommodate up to 16 guests in seven staterooms, and 13 crew. Luxurious touches include a gym, spa pool, beach club area aft of the tender garage, and elevator serving four of the decks.
