    Re: A credible AIS track for the Costa Concordia
    From: Hewitt Schlereth

    Why a gash 16% of the ship's length should sink her puzzles me, and I hope 
    will eventually be answered. As I recall, the reason the Titanic went down 
    was her watertight bulkheads went only halfway up the vertical span of the 
    hull, so when one compartment filled, the water spilled into the next and so 
    It also seems possible that the Concordia may have been sinking level and 
    listed only when she landed on the sloped seabed.

    keep up to reduce the consequences of groundings, collisions, and acts of war

    does the sums and figures the cost of putting in a double hull against the 
    risk of the oil getting out and causing vast amounts of compensation 
    liability as it spreads itself about. Then there is the cost putting a double 
    hull in a cruise ship against the compensation on some people dying if the 
    single hull loses integrity due to something or other. Hmm, tough one...
