This equipment is available now, and I understand that many British ferries are already fitted with voice-recording.
It is possible to make such equipment 'float free', in a similar way to that used for life-rafts and emergency-position-indicating radio beacons, thus ensuring that even when such vessels are lost in atrocious weather, in remote areas, some record remains. All that is needed is legislation requiring that it be fitted.
As a serving merchant navy deck officer, I would welcome such equipment, as it would protect the competent from undeserved vilification and ensure that the incompetent and negligent were correctly identified.
In the end, however safe and survivable vessels are, the best protection is a well- trained and dedicated crew.
