I understand that perfectly, the only point being that no matter where the ship sank in that region there will be a rocky outcrop nearby. It doesn't follow that this rocky outcrop caused the breach in the hull. The USS Park Victory that was wrecked in a similar region in 1947 happened because the captain didn't anchor properly and the vessel was thrown into the icy rocks (he was named and prosecuted BTW, in the same way drivers involved in car crashes are: they are supposed to be in control of their machine). Likewise, the TITANIC crashed into an iceberg. Many shipwrecks off Devon and Cornwall in ye olden days was due to their crashing INTO rocks, not hitting them at the bottom.
