Abstract:
Systems and methods for displaying a marine signaling device are disclosed. A flag coupled to a top section of a telescoping shaft includes a folding arm pivotally coupled to the top section that folds upward to gather the flag into alignment with the telescoping shaft. A housing couples to a boat and supports the shaft in the display configuration and receives the shaft in the storage configuration. As the shaft is retracted, the folding arm contacts an upper surface of the housing and gathers the flag into alignment with the shaft. A motor automatically extends/retracts the shaft based on detected tension on a tow rope mount of the boat or a tow rope coupled to the boat. A tension switch detects tension and activates the motor based on the detected tension. The tension switch may include arms that rotate in response to tension to activate a limit switch.
