A remote control device for a vessel is installed in a vessel and remotely controls a vessel propulsion device of the vessel. The remote control device includes an operation member, an operation load applying mechanism, a control section, and an actuator. The operation member is supported rotatably around a rotation axis, and is operated by an operator to switch the shift position of a forward-reverse switching mechanism in the vessel propulsion device according to the operation angle of the operation member. The operation load applying mechanism applies an operation load to the operation member. The control section controls the operation load. The operation load applying mechanism includes an actuator that adjusts the operation load. The control section is arranged to control the actuator based on a vessel speed of the vessel.
