What is S-VDR? What data items must be recorded by the S-VDR as per IMO Resolution ?

Simplified Voyage Data Recorder (S-VDR), as defined by the requirements of IMO Performance Standard MSC.163(78), is a lower cost simplified version VDR for small ships with only basic ship’s data recorded. It is not required to store the same level of detailed data as a standard VDR, but nonetheless should maintain a store, in a secure and retrievable form, of information concerning the position, movement, physical status, command and control of a vessel over the period leading up to and following an incident.

Hence, the principle difference between VDR and S-VDR lays in the requirements for recording of additional data
