Catalina...2 words....cold....low visibility. Average temp about 58, average visibility, about 10 ft. I have a drysuit. Why do I dive it? Because it is there. Actually, it is the only place I have seen blue/green starfish with mother of pearl looking bumps....incredibly beautiful! I booked a dive boat for Catalina 9/22. This time I'm taking my camera! Aren't most of the short cruises with great dive spots out of Texas and Florida? If you go on the trip and can find the time, diving La Jolla cove in San Diego the day before, or the morning of boarding is recommended. Do you think the others on this site think we should be chatting on a dive forum?
