Overblue 54 is a displacement power catamaran that is fuel efficient due to low hydrodynamic drag. Twin catamaran hulls also reduce weight and displacement resulting in better speed with greater efficiency. Catamaran hull design also reduces role and eliminates pendulum effect giving the benefit of comfortable cruising in safety. Why a power catamaran? Because of stability (seaworthiness), better cruising speeds, fuel efficiency, maneuverability (twin engines + thrusters), comfort at anchorage, and living-aboard and entertaining space. Why a houseboat? Because of volume, comfort, large living spaces, headroom, one level floor, home appliances and one of a kind Flybridge space comparable to super yachts.
