So your information comes from something you read but you can't remember were it was, who it was by or what it actually said?
Herald of free enterprise did not have a pivoting visor, it had clamshell doors. It was completely different in function and construction. It sank because they were left open.
Once again the EIPRB buoys on the Estonia failed to activate because they weren't turned on by the crew when the ship sank, They were not automatic.
If you recall, the recommendations in the public inquiry into The Herald of Free Enterprise was that a 'gate' be provided to cover the car deck door as a safety feature. This is what the bow visor is in working practice.
Thanks for your opinion on the EPIRB's. The JAIC however does not back you up.
