So once again we have confirmation, this time from erwinl, that ships which sank fast were either torpedoed or collided into.
Yet the claim is, the
Estonia's hull was intact yet followed the pattern of a collided ship, which would explain the speed of sinking. However, this was not even considered when Bildt announced the same day as the sinking that it was the bow visor's fault, when no-one had even yet located the wreck.
And despite being torpedoed by the Brits in the Battle of Jutland, well, well, well, it managed to stay afloat for twenty minutes:

Yet the Estonia sank took just fifteen minutes longer to sink, despite not having had one or two torpedoes slicing it in half nor igniting an explosion!
NB: the
Pommern is not included in the table of fastest sinking ships as it was a dreadnought battleship and not a passenger ship.
The carnival cruise ships which collided didn't sink at all which proves their hulls were not breached and they were able to carry on sailing.
