The heavy weight of the engines was causing a bend in Titanic's double bottom. Does this mean the double bottom was weakened and did the breakup start there? this would go perfectly with the V breakup theory, because the double bottom would of held on and water would seep through, causing the bow to rise and the stern to sink. If there was no water in the stern, flooding would be minimal. Eye witness accounts inform us that the bow seemed to rise. After all, B deck was considered "A strength deck". Even though the Aft. expansion joint was there. But the usual bow pulls stern down theory could also be truthful, that's probable why the stern sank. Or it may be that the titanic had no power so the water tight doors failed, even though they might be hand operated as well. here is a good theory (even though its 11 years old) Good day!
