FLIP, the FLoating Instrument Platform, is not a ship, but a 355-foot-long research platform that can be deployed for oceanographic research. Designed by scientists at Scripps's Marine Physical Laboratory, FLIP is operated by Scripps Oceanography for the U.S. Navy.

Normally docked with Scripps’s fleet in San Diego Bay, FLIP can be towed to out to sea in its horizontal position and then “flipped” 90 degrees so that 300 feet of its length are under water. This turns FLIP into a “spar buoy,” a tall, thin, weighty structure designed to be uniquely stable and resistant to wave motion.

FLIP was built in 1962 to help study long-range sound propagation for submarine warfare, but the platform has since supported research in geophysics, meteorology, physical oceanography, and other scientific fields. Its unique appearance and method of deployment have also made it a worldwide curiosity and the subject of many documentaries.
