One thing I do know, I never enjoy meeting a crusie liner, and I do mean, ANY Cruise Liner out at sea.

I have made safe passing agreements with everyone I have ever met and they have NEVER kept to the meeting agreement. We would both promise to turn right 10 degrees and they will consistently give me a 2 degree turn at the most.

The major factors in the M/V STOCKHOLM and M/V ANDREA DORIA collision was: 1) going too fast in limited visibility (sea fog, Both vessels), 2) Lack of knowledge and experience in using their RADAR (Andrea Doria), and 3) Departing from the Rules of the Road (Andrea Doria kept turning to the left/Port).

It all came down to the M/V ANDREA DORIA was more concerned in "docking in New York per their schedule" than in practising common sense and good seamanship, in adverse weather conditions.
