1. Don't you think it would have been intellectually honest to include the Herald of Free Enterprise in your list? After all, it too capsized (and would have entirely sunk if it had been in deeper water) because there was a gaping hole in its bow. Do you know how long - measured from the time of the first ingress of water through the bow - the HOFE took to capsize, Vixen? Shall I tell you? It was 90 seconds.
2. You still seem unable or unwilling to comprehend that a ship with a) a gaping hole in its bow, and b) vast open vehicle decks directly connected to that gaping hole in the bow, take on water extremely quickly and destabilise extremely quickly. See: a torpedo might create a breach in the hull of 2-3 square metres, and that breach would almost always be on the side of the ship. By contrast, a gaping open bow would present a breach of over a dozen square metres, and that breach would be in the very worst place for water ingress (for obvious reasons). And the internal compartmentalisation of "regular" ships - by which I mean ships without vehicle decks - would create numerous baffles which would slow down the passage of water through the ship and therefore provide a form of defence against rapid destabilisation; by contrast, huge volumes of water pouring into an open vehicle deck (which is more-or-less the entire dimensions of the ship) causes rapid destabilisation, since the water can slide across the ship virtually unencumbered - and once the ship starts listing, even if only by several degrees, the water will rush to that low side of the ship and accelerate the list.
In short: you have no idea what you're talking about.
