I am a retired Navy Captain with 30 years of service and a Doctor with 2 postgraduate degrees. My spouse is retired and has a computer science engineering degree. I have spent 2 years aboard a naval aircraft-carrier and 2 years aboard a naval destroyer tender, which had approximately the same propulsion system as the Seven Seas Navigator, two controllable pitch propellers.
We departed New York Harbor 26 Sept 2015 around 8:00 PM. As the ship began backing away from the pier, we noticed heavy vibrations and the rear section of the ship began shacking violently. The heavy vibrations and violent shacking remained throughout the duration of the cruise. We noticed that the Captain reduced the cruising speed to try and reduce the vibrations. At times it become much worse. We had approximately 3 hrs of sleep that night, with calm seas.
27 Sept., we arrived in Newport, Rhode Island on time in calm seas, with blue skies and high clouds. Departed on time calm seas. Heavy vibrations and noise from ceiling, drawers, cabinets and doors. Unable to sleep, period.
The carpet was stained,damp and smelled of mold. The vernier on the drawers in the stateroom was cracked and pealing off. The drapes were worn and the lining was torn. The wall and ceiling vibrated so loudly that we were unable to sleep.
