A watercraft control system includes a watercraft and a communication device. The communication device includes a communication unit configured to transmit information indicating a location of the communication device to the watercraft. The watercraft includes a communication unit configured to receive the information indicating the location of the communication device and a difference calculation unit configured to calculate a difference between the location of the communication device and a location of the watercraft.

This automatic ship handling system includes a ship and a communication device, the ship includes an actuator that has a function of generating a propulsion force for the ship and a function of generating a turning moment on the ship, an operation unit that receives an input operation for activating the actuator, and a ship control device that activates the actuator on the basis of at least the input operation received by the operation unit, the ship control device has a manual ship handling mode in which the actuator is activated on the basis of the input operation received by the operation unit, and an automatic ship handling mode in which the actuator is activated without a need for the operation unit to receive the input operation, and in the automatic ship handling mode, the ship control device controls a speed of the ship on the basis of a relative distance between the ship and the communication device.

A location indicator assembly has a support mechanism for undergoing movement between a retracted position and a deployed position, an indicator device mounted to the support mechanism, and a mechanism for deploying and retracting the support mechanism to place the indicator device between deployed and retracted states, respectively. A flotation device, such as a life jacket, is equipped with the location indicator assembly to provide high visibility for an individual floating in open water while using the flotation device.

A signal device for maritime distress rescue and a surveillance device for maritime distress rescue are provided. The signal device for maritime distress rescue which is carried by a user aboard a vessel may include a first communicator configured to communicate with a surveillance device for maritime distress rescue of the vessel, a first position detector configured to generate first position information of the signal device at a predetermined time interval, and a first controller configured to receive second position information of the surveillance device from the surveillance device at a predetermined time interval and determine whether the first position information is within a safe area of the vessel that is set on the basis of the second position information. Accordingly, when a distress occurs, it is possible to transmit a distress signal without operating a switch while minimizing power consumption of the signal device.

Visual safety device providing a caution wristband and alert flag designed to protect a water sport participant from surrounding boat traffic. The safety device includes a rolled up banner attached to a wristband to be worn by a water sport participant. A downed water sport participant, such as a water skier, wakesurfer, wake boarder, or tuber, manually deploys and waves the alert flag while in the water to notify their boat operator of their location and increasing visibility to oncoming boaters. Once the water sport participant is in a safe position or back on a boat, the alert flag is simply wrapped back into a caution wristband.
