I'm looking for a dive boat that goes out to the Spiegel Grove. I found the Rainbow Reef online. It looks promising because 1/2 of us aren't divers and they offer bubblewatcher rates of $15. They also have a 6 pack that we could book (there are 6 of us) for the trip. Any experiences with them? Any recommendations for others that could accomodate 3 divers and 3 non divers for a 2 tank trip?
