So it sunk because...?
Because water came in faster than they could chuck it out again. What's your point?

Or so you say. But since it wasn't in open seas to demonstrate what you claim would have happened had it been, it's not evidence of what you claim would have happened.
There is absolutely no way a reader could honestly misconstrue a post so completely.So the short answer is no, only if it has leaky seams.
It would depend on the circumstances.
The direct comparison with the Herald of Free Enterprise is the ferry ro-ro, Jan Heweliusz.
It is astonishing that someone who professes to be a master of shipbuilding, architecture and engineering did not know of this elementary principle.

Their point being that if the sample hadn't been heat treated in the lab then signs of heat treatment must have been present before it got to the lab. You then seized upon this, assuming they meant such heating could only normally be achieved in a lab, and went galloping off in all directions with it. Your basic misunderstanding led to goodness knows how many posts about welding. None of it matters. You just didn't understand what they meant.
WikiTempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal. Tempering is usually performed after quenching, which is rapid cooling of the metal to put it in its hardest state. Tempering is accomplished by controlled heating of the quenched work-piece to a temperature below its "lower critical temperature".
Seriously, you are claiming metallurgy credentials and you are trying to get us to believe people can temper steel on their bathroom floor.
The discussion wasn't 'how hot can welding systems burn'. We were discussing why Clausthal-Zellerfeld said assuming Braidwood's sample had not been heated to 700°C then XYZ follows. The significance of the 700°C is to do with at what temperature causes a change in the inherent structure of the steel.
The Herald of Free Enterprise ended up like this. Stop making fabrications about it having sunk to the bottom of the sea like the Estonia.
Nonsense: a simple yes or no doesn't suffice, because my whole point is that such simplistic scenario-mongering as you insist upon doesn't provide useful knowledge. A boat sinks for exactly and only one reason: it has lost buoyancy. The reasons why it might lose buoyancy are many and varied. In the case of Viking ships, yes, they will sink if they ship too much water, which can happen if they roll too far, if they ship water over the bows, or if water enters via the notoriously leaky seams, or any other of a dozen other scenarios I can imagine. The Vikings knew this, which is why bailing the ships is such a prominently-mentioned aspect of their narratives.
The real point remains how you are being confronted with the knowledge and experience of people who have designed, built, and operated large oceangoing vessels as part of their professions, as well as studied professionally the failures in those endeavors that occasionally befall us. Yet you -- who have done none of these things -- rely almost exclusively on your own ill-informed say-so to attempt to make your point. Explain why a reasonable person should not dismiss your arguments as arrogant crackpottery.
Yes, it sank otherwise it would be afloatIt did not sink. It lay on its side.
Had it been in open seas it would have floated belly up

It was on the bottom of the sea.

What is your evidence it would have floated 'belly up'?
heh. A good piece of sophistry there to hide the fact it was a very different sinking from the Estonia
...such an outrageous attempt to obfuscate the matter.
