Voyage Data Recorder

A Sperry VDR

A Voyage Data Recorder (VDR) is a small, buoyant and resilient emergency recording device. It stores looped recordings of machinery information, alarm states, navigational data, wheelhouse audio and radar data. In the event of a vessel loss event, the VDR will hydrostatically release and float away. The VDR will begin broadcasting a locating signal. This functionality is similar to the black box device in aircraft (and, similarly, is actually a bright orange).
