Interesting article and pictures. The Oriskany accomplished alot during her service. http://www.irishmansoftware.com/Oriskany.htm
I guess that small boat was providing radio communications/power for the remote detonation. Notice the arial on top.
Very impressive array of pics, CTDave. It's a wonder the small boat didn't capsize in all the turbulence or get sucked down. Yeah, she was junk, but still sad to see a boat go down nonetheless.
