I took a tour of the FLIP back in 2002 when my wife was working aboard the Robert G. Sproul at Scripps and it is one of the most interesting ships I’ve ever seen. The Scripps website tells us alittle about this amazing vessel:
FLIP stands for Floating Instrument Platform: it is actually a huge specialized buoy. One of its creators described it as looking like a 355-foot long ( 108 m) baseball bat. If that isn’t unusual enough, it really flips!
Popular Mechanics is featuring the FLIP in this month’s magazine. Here are some highlights from the story:
Shaped like a giant baseball bat, the 700-ton FLIP, or Floating Instrument Platform, is a Navy barge operated by Scripps Institution of Oceanography in San Diego. Once towed to a site, the vessel flips to vertical. “It was built in 1962 to refine acoustic targeting for submarine rockets, but scientists quickly realized that it would be useful for all kinds of research,” says Bill Gaines, FLIP’s program director. “So 45 years later, FLIP still serves the oceanographic community.” And it is still one of a kind.
Stability
Tanks 5, 8 and 9, and parts of tanks 6 and 7, remain filled with air to keep FLIP buoyant. Like the Louisville Slugger that the vessel was modeled from, FLIP increases in diameter from bow to stern — a profile that contributes to its stability when vertical. “A design criterion for FLIP was that it move less than one-tenth of a passing wave’s height,” Gaines says.

I worked in San Diego for a few years. Seemed to me that FLIP spent most of it’s time at the dock… but it sure was a sight to see when it did go out.
Superb vessel! I am building a fully working scale model of FLIP so any photos/footage appreciated- Cabin photos also needed so I can really do a good job! Thanks in advance for your help. Kev
