It is absolute nonsense to say that because there is a rock nearby that it must have been the cause of the damage, when nobody has even done any calculations as of yet.
Breaches in the hull occur where they are expected to be found. For example, the SS
Park Victory that hit rocks in 1947 in a severe blizzard, was found to have a breach exactly at the boiler room portion where it also hit a rock and you can see the curled metal.
With the
Wilhelm Gustloff a
Kraft durch Freude cruise ship being used to evacuate East Prussian Germans away from Danzig (now Gdansk), and loaded with about 10,000 fleeing refuges, wounded soldiers and nurses, it was sunk by a Soviet submarine the S-13 captained by Marinesco and torpedoed in three places: the bow, the stern and the auxiliary nurisng quarters ( a fourth failed to launch). The Wilhelm Gustloff was on the Zwangweg 58 ('Fairway 58') rather than running close to the shore and with just a small escort ship. It sank at just six fathoms or ten metres near the
Stolpe Bank. Thus, we have a ship a similar length to the
Estonia at 166m sinking in quite shallow water and with a rocky seabed.
When examined, the
Wilhelm Gustloff was exactly damaged in the three places we expected to see it damaged.
The breach on the hull of the
Estonia hasn't happened by chance. However, obviously, we want to rule this out.
