This will result in greater fuel efficiency as it takes less power to push through the water and usually a greater speed than that beamy vessel of the same length each given the same power plant. It is similar to the aerodynamics that go into making automobiles more fuel efficient. A slick deign in the in the wind tunnel will help with MPG in the real world.
