Owned by the U.S. Office of Naval Research, this ship named the R/P FLIP is used to study acoustic waves underwater in reference to ship noise. The entire 355-foot long ship can partially flood causing it to pitch backward 90 degrees. The end result is only 55 feet of the front of the ship sticks out of the water looking similar to a capsized ship. Wen turned on end, the entire ship is very stable and is very immune to waves due to the bulk of its weight being underwater. To have a look at what is perhaps the craziest ship ever designed, you can check out the video below.
