What is your evidence for this? Water on the car deck would have gone straight down in to the hull through open hatchways and stairways.
It would have filled the machinery spaces, they are the largest open areas and span multiple decks, it's the reason ships usually sink by the stern.
Why would it have been any louder than the noise of the water flooding through a hole caused by a submarine or down the stairwells or in through the broken windows?
Didn't the bombs blow the bow visor off and let the water in?
Make your mind up.
They reported loud noises and movements consistent with a ship losing it's bow visor in a storm and the ship heeling over as it foundered
Do look at MS Jan Heweliusz. The reason the Estonia sank in 35 minutes and the MS Jan Heweliusz over several days underlines the point that the JAIC should have investigated (a) the speed in which it sank, (b) the passengers' accounts of explosions/collision and (c) the reason for the hole in the starboard hull and superstructure.
Your saying all of this is consistent with a ship losing it's bow visor in a storm and the ship heeling over as it foundered, does not constitute 'an investigation' in the normal meaning of the word.
