Abstract
A ship's maneuvering simulator comprises a wheel house of a ship having a projection screen spaced therefrom and a point light source-shadow image projector provided for the projection of a shadow image, and one or more scale models and air-water images controlled by a computer, and a projection device for the projection of a motionless part of a forepart of a ship that is visible from the wheel house. At least two plane translucent projection screens are provided that join one another at an angle, and behind each projection screen the point light source-shadow image projector is mounted such that the central position in the wheel house and the stationary point light source are positioned symmetrically with respect to this projection screen and the models provided are uniform.
