SailorJack, are you trying to say you're a jinx?
I highly doubt that. This honor belongs to one of my aunts. Every ship she ever sailed eventually sank. She also believes she started the NYC blackout of 1965 when she plugged in an old appliance.
You mentioned Costa -- have you every been on Federico C? I knew her as SeaBreeze, and she is my favorite ship of all time. May she rest in peace.
