 But it was quickly clear that the ship had broken its back, and the bow section came to rest in 450 m of water.On 14 April, the 250 m long main body sank from the coast, between Arenzano and Cogoleto.After the wreck was declared safe, a mini sub diver found that the stern section had grazed a rocky spur, though not hard enough to open any new holes in the hull, and come to rest at an angle on the flat, sandy seabed.
