Fuel Efficiency
Navigator Yachts hull shape was designed with one thing in mind: make the best use of a minimum amount of fuel and horsepower, and retain the maximum amount of boat speed and efficiency. In doing so, Navigator created a wide hull shape that is stable at rest and at displacement speed, while achieving 30% less wetted running surface when on a plane. The result is a hull with much less drag, a significantly smoother ride, and far better fuel economy.
