Around 1990, some officers from Navsea, the navy’s research and acquisitions branch, visited my office to discuss a new power trimaran design. I showed them my Lightspeed 150 power tri design. It pretty much looked like this picture,  with a different cabin.  They were impressed with the possible efficiency.  And I learned that a tri can mask the boat’s thermal signature from Exocets.  They suggested that I go with them to a topless bar and discuss the project.  I had a very feminist office manager at that time.  She let them know what she thought of that.  I never heard from them again.   Until friend Chris forwarded this to me.   http://www.popularmechanics.com/military/navy-ships/a20197/darpas-autonomous-sub-hunting-ship-takes-to-the-sea/
