Claims

[Scope of utility model registration request]

In a ship with an open-bottom hold in which the left and right hold bottom plates are installed diagonally in an inverted V-shape with respect to the vertical hull centerline at an appropriate distance above the bottom shell, the hold bottom plate is installed along the vertical hull centerline. A rectangular cargo dumping port, a pair of left and right sliding doors that can move laterally along the hold bottom plate and form an angle of inclination greater than the angle of repose of the cargo, and open and close the cargo dumping port, and the slider. A ship with an open bottom hold, characterized by being equipped with a power device that moves the door.
