Document Type and Number:
Japanese Patent JP7375077
Kind Code:
B2
Abstract:
Provided are a stern add-on structure and a ship with which it is possible to mitigate thrust loss and save energy. This ship 1 comprises a stern add-on structure 2 disposed on a ship bottom 12 above a propeller 11, and the stern add-on structure 2 includes a first surface 21 positioned in front of the position of the propeller 11, and a second surface 22 positioned in rear of the position of the propeller 11. By providing the stern add-on structure 2, it is possible to: decrease a force F1 pulling the hull backward and to increase a force F2 pushing the hull forward; obtain propulsion force from the pressure difference generated on the first surface 21 and the second surface 22; and mitigate thrust loss and save energy.
