Abstract: The present invention addresses the problem of providing a ship that can recognize the correct position of itself on the sea. A ship (100) comprises a recognition controller (160) that recognizes the position of the ship on the sea, the recognition controller (160) recognizing the position of the ship on the sea on the basis of relative distances between the ship (100) and a plurality of land-based targets. The recognition controller (160) captures an image (P1) of a structure (S1) and an image (P2) of a structure (S2) by using a first camera (161) and a second camera (162), respectively, and maneuvers the ship such that the sizes of the captured image (P1) and image (P2) do not change and thereby maintains a fixed point on the sea.

Abstract: A hydraulic and mechanical composite continuously variable transmission (HMT) is disclosed. The HMT includes a hydraulic continuously variable transmission (HST) and a mechanical speed change mechanism using a group of planetary gears as the differential part. The output rotation of the HST and the rotation of the input part of the mechanical speed change mechanism that receives power from the engine are transmitted to the differential part which translates the rotation to a speed change output shaft. The speed change input part is formed at one end of a pump shaft and the differential input part is coaxially formed at the other end thereof. Further, the operator may manually set the speed ratio via electrical means on the mechanical speed chance mechanism.
