This time might have been at low tide and all bunkers full of fuel since he had just set out from port. The ship reportedly drew only 25 feet. That would suggest it would be top heavy and subject to a roll over. |

I guess it doesn't matter how many nav aids a ship has if the chief nav aid (read captain) has a faulty cpu. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |

Had he sailed straight on he would probably have passed clear of the rocks, as he had done before. But he turned the bow right and the stern went left, because of inertia, hitting the rocks on the left side of the ship. Tullio |

However looking into it, I now discover that Carnival now own all of them, including Costa ... Thought you knew that from my earlier post about Carnival running into things. |

Cruise shipping has become a carnival. The Captain and his officers must entertain their passengers. Seamanship is no longer required. Tullio |

Yes. he was the Comandante in seconda, the senior officer after the Captain. My brother had that role on the Michelangelo liner. Tullio |

Do passenger ship designs include watertight compartments to protect against severe flooding? All modern ships have watertight compartments, some are better than others. The Titanic had around 6 watertight doors (I don't remember the exact number). |

A bigger question to ask is how much can she list and still operate her lifeboats? That was one of the issues with the Titanic so there is no excuse to not abandon ship before she reaches that point. It sounds like from some media reports some of the lifeboats did tip enough from scraping the sides to put people in the water. The problems with the Titanic were many, there weren't enough lifeboats, there had been no lifeboat drill and no one knew what to do to abandon ship, and remember, the Titanic was "unsinkable". |

Every new generation or two they have to learn the lesson again from the school of hard knocks. |

In this day and age how does a ship with every nav aid hit a reef leaving port? ...by not watching where there going!! The Kite Fliers -------------------- Kite fliers: An imaginary club of solo members, those who don't yet belong to a formal team so "fly their own kites" - as the saying goes. |

His wheel watcher forgot which way was starboard. |

Unfortunately, they were not completely watertight in that they did not reach from deck to bulkhead. As the bow went down, the fullly flooded compartments tipped over into the next & so on. Since then, all watertight doors must be deck to bulkhead. |

IIRC recently there was discussion in the news about that. The engineer was on-board and knew before sinking that the berg had put a hole through enough separate compartments that she would sink. IIRC she could take four being flooded, the hole got six. |

Costa Concordia will be floated and righted by an American firm, then towed to a harbor and scrapped. A new Costa Crociere ship. Costa Fascinosa, will sail in May for its maiden voyage. Tullio |

Visits to the bridge are to be restricted and ships will have to carry more lifejackets under new cruise ship safety requirements agreed by the industry in the wake of the Costa Concordia disaster. We've only been sailing ships for about 2 to 3 thousand years yet they still can't get the rules, regulations or procedures right.

The Italian Government has established that ships bigger ha 500 tons must stay away 2 km from isles and small harbors. The Liguria shopkeepers are protesting that in the deep Tyrrhenian Sea ships cannot drop anchors at that distance from the shore and send passengers ashore to spend their money by motorboats, while ships could anchor in the shallower Adriatic Sea. A compromise is likely to follow. Tullio |

What hasn't been mentioned is why the ship was so vulnerable to a hole in it's hull... Has nothing been learnt for ship design since the Titanic or Herald of Free Enterprise disasters? Well... Car ferry design has been modified in a minor way to reduce the possibility of a very rapid capsize due to water sloshing across a car deck. But what of passenger ships? How does the safety there compare to the extreme lengths taken to make airliners safe? Two solutions come to mind that would have kept the Italian cruise ship afloat and upright despite huge holes below the waterline: 1: Watertight longitudinal bulkheads along with the more normal transverse bulkheads; 2: Gas powered rapid-set expanding foam to flood a water flooded area with buoyant foam that could also seal up any hole. There must also be two layers of mesh loosely fitted on the inner side of the hull that would stretch during the collision but act to hold the foam in place. The foam system could be made as part of the existing water fire suppression system pipework. Worth patenting so that I can make my millions? ;-) Cheers, Martin See new freedom: Mageia Linux Take a look for yourself: Linux Format The Future is what We all make IT (GPLv3) |

I think ship design is very conservative, compared to aircraft design. The best solution is to stay away from rocky coasts, as my brother has done in his 40 year career as a seaman and captain. Tullio |
