Powered by a hybrid propulsion system comprising two 1,920 hp main engines and two 80 hp electric motors, the Columbus Sport Hybrid 40M (www.columbusyachts.it) provides high performance and eco-friendly operation. The aluminum-hull yacht reaches a top speed of 22 knots and burns just 58 gallons of fuel per hour when cruising at 15 knots; at 8 knots, it burns only 15 gallons per hour. When propelled by only the electric motors, the yacht travels nearly silently and with hardly any vibrations. The first Sport Hybrid 40M, which launched in August, was outfitted with marble surfaces, stainless-steel fixtures, and floors made from sustainably sourced oak. The yacht accommodates 11 guests in five staterooms. The starting price is nearly $22.8 million.
