I remember seeing part of a movie about a bunch of commandos or other "hard men" that storm a ship at sea only to be suprised by a hoard of zombies on the ship. What is that movie? This is driving me crazy...
Hmmm, bad ships. Do you mean Deep Rising about a cruise ship being boarded by raiders/ pirates, only to find that all the passengers and crew are gone, attacked by a sea monster? Came out in 1998.
And there is Ghost Ship from 2002. Also a ship without a crew, on which strange things happen as soon as people board it.
