Remote control device for vessel and remote control method for vessel propulsion device

A remote control device for a vessel that is installed in a vessel and remotely controls a vessel propulsion device of the vessel, the remote control device comprising:

• an operation member that is supported rotatably around a rotation axis, and is operated by an operator to switch a shift position of a forward-reverse switching mechanism in the vessel propulsion device according to an operation angle of the operation member;
• an operation load applying mechanism that applies an operation load to the operation member and includes an actuator that adjusts the operation load;
• and
• a control section programmed to control the operation load by controlling the actuator based on a vessel speed of the vessel;
• wherein
• the vessel propulsion device includes an engine;
• and
• the operation member includes a single lever that is operated by the operator to both switch the shift position of the forward-reverse switching mechanism and change a throttle opening degree of the engine according to the operation angle of the operation member.
