PURPOSE:To reduce resistance due to wind at the time of steaming, by a method wherein a resistance-reducing bodies each of has such a shape as to become smaller in the direction of spacing away from a superstructure of a ship's hull are fitted to the bow side and the stern side of the superstructure. CONSTITUTION:The resistance-reducing bodies 3, 4 each of which has such a shape as to become smaller in the direction of spacing away from the superstructure 2 are fitted respectively to the bow side and the stern side of the superstructure 2, which is fitted on an uper deck 7 of the ship's hull and on which a steering room 5 is placed. The resistance-reducing bodies 3, 4 are composed of sheets 8, 9 so that they can be detachably fitted onto the upper deck 7, and function to reduce the effect of the wind pressure exerted on the superstructure 2 at the time of steaming. |
