This is a prime example of why Solo certification should be recognized by dive operators world-wide. I've found that in most situations it's much safer diving solo when properly equipped, skilled, and experienced than being forced to depend on bozo buddies like that one.
The other poster hit the nail on the head. It is hard to plan work schedules around dive trips for most divers. Because of these conflicting schedules alot of divers postpone, or simply cancel trips. If the Dive operators would figure the money their missing out on because of this, I believe that they would find that the extra cost of liability insurance to cover solo certified divers would most likely be an insignificant hurdle. I've cancelled many dive trips in the past because a buddy backed out. If the Dive operators would have accepted Solo Certification I'd went on the trip without my regular buddy regardless.
I've been paired up with a few buddies like the one you had. Noone will ever convince me that diving with a buddy is safer than diving as a properly skilled, experienced, and equipped certified solo diver is.
I think you did the right things underwater, but you really should have went to the captain, or dive trip leader to make them aware of this guys behavior. What if he'd killed the next buddy on that second dive. There's a good chance you could've saved that persons life if you had made that information known. I do think you allowed yourself to be placed in a bad situation to begin with. Being paired with a complete stranger is never a good idea. There's just no sure way to tell how safe they are. (no matter what their certification level is)
In my personal, but humble opinion, I feel that the liability issues involved with diving with a strange buddy carry a far greater risk than the alternatives of: 1.) Cancelling the trip all together, and not going without a regular buddy that you trust. 2.) Getting solo certified, and go to a destination where this is accepted. (sadly there are few that do) 3.) Charter your own boat, and do what the heck you want to do. (this is mostly what I do) The heck with cattle boats. and last but definitely not least 4.) Hook-up with a group of divers that you know you trust that are planning a nice all-inclusive trip. This allows you plenty of time to figure out who you want to pair up with on your dives. Get to know them. Get with them at a local area (even if it has to be only in a pool somewhere) and see what they know. Lots of telltale signs to be had here. At least talk to them, and the absolutely compare log books long before you board the boat in agreement to dive with them. Remember, we are all at risk of being sued when agreeing to be someone elses dive buddy, no matter what forms we sign, or what agreements we make verbally.
I dive with the attitude that diving without freedom is usually no fun at all anyway. You are in control of your own life. Not the Captain, group leader, or Professional divers in your group. You make the calls when it comes to your own life. Be nice, but if you know you're in the right, just tell it like it is. No exceptions!
