2. Description of the Related Art Conventionally, when a ship travels on a shallow water of a sea or lake, a rocky reef, or a place where the water depth changes drastically, the rudder and propeller are pulled up so that the water bottom does not come into contact with the rudder or propeller. At this time, a large force is required to pull up the rudder and propeller manually, and it is difficult for one person to pull up at the same time. Needed people. Also,
There was also a device that lifts the rudder and propeller with hydraulic drive etc.,
Since they were operated independently of each other, a plurality of persons were required to simultaneously perform a plurality of operations of rudder pull-up, propeller pull-up and steering. Especially when traveling in places where rocks are frequently raised and lowered, the work load on humans is heavy because it is necessary to respond promptly.
