The MV Estonia sinking 1994 was allegedly caused by water loaded in the superstructure whereby the vessel heeled and sank. In 2005 the Swedish government decided that the sinking should be clarified in more detail. On May 23, 2008, two research consortia presented their findings. One finding is that a ferry floats on its deck house! The deck house side may be 10 metres below water ... and the deck house is still not flooded and provides buoyancy to prevent capsize. This amazing finding - in contradiction to international safety (IMO/SOLAS) standards - is analyzed at http://heiwaco.tripod.com/news.htm . It seems that the two ship safety research consortia manipulated their findings to support a 'politically correct' suggestion. This is evidently unacceptable and does not promote real safety at sea.
I was intrigued by your comment Mr Bjorkman, and tried to follow your link. I got a warning from my anti-virus to disconnect!
Consequently I could not read the analysis. However, we all know that weathertight superstructures and deckhouses provide buoyancy in the damaged condition. The margin line can be far above the freeboard deck.
Could you kindly explain why you say it is amazing and how it contravenes SOLAS.
