Navigational running light retrofit system comprises a position tube that is inserted into a U.S. Naval specified navigational running light fixture and is further positioned, aligned and sealed using existing elements of the navigational running light fixture being retrofit. The positioning tube, having a generally tubular form, is a receiver for a commercially available LED navigational running light having cylindrical form. LED navigational running light is modified to secure a plate to the top surface of the assembly. This stabilizer plate has a similar diameter to the inner housing of the navigational running light fixture being retrofit, whereby stabilizing the retrofit system assembly when subjected to extreme mechanical shock. The positioning elements of the navigational running light retrofit system cooperate with the elements of the navigational running light fixture being retrofit to align and maintain alignment of the light exiting the fixture at the direction and angle.

A watercraft safety lighting system includes one or more light sensors for measuring ambient light levels, which are operatively connected to an electronic controller, such as a programmable logic controller or any suitable programmable computing device. The navigation lights are operatively connected to the electronic controller, as well as docking lights, interior lights, and instrument panel lighting, such as the lighting for gauges, instrument panels, video screens, GPS monitors, and the like. When ambient light levels reach a predetermined level of low light (as darkness is setting in, for example), the electronic controller is programmed to switch on the navigation lights, and to adjust other lighting to appropriate levels for night-time operations. The system may also shut off docking lights at a predetermined speed after dark, and may include alarms to warn the boat captain of improper lighting settings in low-light conditions.

A distress signal system for a sea vessel comprises several navigation lights (11, 12, 13, 14, 15), which are connected in an electrical circuit and arranged to emit a steady light in different directions in a normal operating state. The distress signal system comprises a control means (28, 30) connected to the electrical circuit which in a distress signal state is arranged to vary the current to the navigation lights (11, 12, 13, 14, 15) in order to vary the light emission therefrom in accordance with a distress signal, such as SOS. A manually actuatable actuator (24) is connected to the control means (28, 30) to activate or deactivate the distress signal state. A light activating means (26) is arranged to provide a varied power supply to the navigation lights (11, 12, 13, 14, 15) in connection with activating the distress state, regardless of whether these are in operating state or not. Such a distress signal system can be provided by connecting a separate distress signal unit comprising a control means to the navigation lights of a sea vessel.

A boat anchor monitoring system is disclosed and includes a status indicator and an anchor module that are operable to communicate with a base module. The anchor module includes a transmitter operable to transmit a signal containing a data payload on a set schedule. The base module on the boat is operable to determine if the signal strength exceeds, or is equal to a predetermined threshold value, in order to direct the status indicator to either display the anchor in a “Deployed” or “Not Deployed” position. The system may further include a time measurement component or water contact sensor that will direct the indicator to display the anchor in a deployed position if sufficient time has elapsed with no signal or the anchor module has contacted water. The system is also configured to prevent ignition if the anchor is determined to be deployed.
