A vessel includes a body, such as surfboard, that floats in water. One or more thrusters, and one or more sensors are provided on the body. A controller is configured to selectively activate the thrusters to cause the vessel to move along a path through the water, receive sensor data from the one or more sensors while the vessel is moving along the path, determine, based on the sensor data, whether a dangerous condition is present in the water; and output a warning when the dangerous condition is present in the water. For example, the collected sensor data may relate to locations and directions of currents in the water, the dangerous condition may relate to a rip current, and the warning may identify at least one attribute of the rip current. A map identifying a location of the dangerous condition may be generated and forwarded to other devices.

A lifesaving system for a swimming pool includes a plurality of lifesaving modules. Each module includes a platform and is stowable in a standby configuration under a surface of water in the pool. The module is deployable to rise to a surface of water in the pool beneath a swimmer in distress so as to support the swimmer on the platform.

An unmanned lifeboat 1 has a hull 2 with a transom opening 3, a fo'c'sle 4 closed by a rounded top deck 5, providing accommodation 6 for survivors. The aft deck as such is generally U-shaped with a cut-out 16 open at the transom 17, which is vestigial with two small port and starboard parts. Within the cut-out is a boarding assistance ramp 18. This is level with the aft deck at its forward end and slopes down to the transom. It extends aft of this by a few of feet—say about 1 m—to enable survivors to swim and crawl onto it.

For guidance to reach the vicinity of the survivors, the lifeboat is equipped with a communication apparatus including a receiver 32 for receiving survivor location data. In addition, the navigation apparatus with which the lifeboat is equipped includes a GPS system 33 of its own, a compass 34.

The built-in system for testing the sprinkler system of a lifeboat is characterized in that it has a water tank (17) connected to a pipeline for the water from the water installation of the marine facility (14) which pipeline is equipped with a sprinkler system pump (2). The pipeline for the water from the water installation of the marine facility (14) has a valve for the water from the water installation of the marine facility (15) and is connected to an outboard water inlet pipe of the sprinkler system (4), which pipe has an outboard water valve (5). At a connection point (16), the pipeline for the water from the water installation of the marine facility (14) is connected to the outboard water inlet pipe of the sprinkler system (4). The connection point (16) that connects the pipeline for the water from the water installation of the marine facility (14) to the outboard water inlet pipe of the sprinkler system (4) is located between the outboard water valve (5) of the outboard water inlet pipe of the sprinkler system (4) and the sprinkler system pump (2).
