Jerry,
I dive the "O" about twice a year, and will actually be going out to it Tuesday. The boat ride can be long, O is 22 and a half miles offshore. Regular charter boats usually take 2 hours give or take depending on seas. We go out on a 6-pack 30 foot pro-cat called "Wildcat" captained by Alan. It is a little more cramped than your usual dive boats, but it is FAST. If seas are no more tha 1-2 it only takes 40 minutes. There are other great charters in Pensacola though. Viking Dive Charters is top-notch professional and very safety conscious. MBT and Scuba Shack are also excellent options. If you are coming down alone or with just a couple of people and want buddies send me a message. I am always up for a trip. Jim.
