The Danish cruise ship was constructed in 1974 and met disaster after striking a rock during a cruise in 2000, according to the History channel. The crew sent out a distress signal and arranged for all of the passengers to be safely escorted to a passenger ferry.

The Point San Pablo Yacht Harbor in Richmond, California, contains a sunken vessel that was purposefully placed there as a breakwater — a barrier that protects the harbor from San Francisco Bay's never-ending waves.
Capt. Raymond H. Clark, who started the marina, couldn't afford a breakwater levee, so he came up with the unconventional idea of using sunken ships, according to Point San Pablo Yacht Harbor. He got his hands on condemned wooden schooners and towed them to the best position for the marina.
"This graveyard of coastal steamers was quite picturesque," especially for people fishing for striped bass, which were abundant in the area, Harbor's website said.
