I'll be going on my first Blackbeard Cruise October 28. I have read nothing but good things about them except for rjack321's post. From what I gather, if you don't expect more than spartan accomodations then you'll have great diving at a great price. I can't wait, counting down the days. 
They do have holding tanks for sewage. Blackbeard's is def camping at sea, but for those of us that don't need to be awakened with coffee at 9 am, it was great, I dove, dove, dove, ate, slept, ate, napped and dove some more. I would take some ear plugs in case you are in the galley. Breakfast did not wake me up becuase of the plugs. Definately take your mal de mer drugs just in case (I slept like a baby during a rough patch we had on the first night while other non-believers were hurling). I highly reccomend the experience and can't wait to go back. :14:
