This ship with a small duct is characterized in having a propeller (10) attached to a stern of a hull (1), and a duct (20) attached to the front of the propeller (10), the hull (1) being a small duct having a propeller load condition in actual sea areas of 1.0 or greater and an eddy resistance of 10% or greater, and the diameter of the duct (20) being between 20% and 50% inclusive of the diameter of the propeller (10). Therefore, a hull (1) that yields a horsepower-reducing effect is specified from the relationship between eddy resistance and the propeller load condition, and the shape of the propeller (10) is contrived and a small duct (20) is placed near the front of the propeller (10) as an energy-saving device that has the characteristics of both a large duct and a small duct, whereby cavitation is suppressed and interference with the small duct (20) is utilized to optimize the radial load distribution of the efficiency-governing propeller (10) in actual sea areas where the load rate increases.
