ChrisMan's post made me decide to ask for clarification on something that has been niggling at me as I read this thread: Is it the norm in Hawaii tourist diving (or at least tourist diving in this part of Hawaii) to have guided dives but to not have buddy pairs? In other words, is there a lead DM, a train of un-buddied divers, and then a following DM? I feel like I picked that up in earlier posts, but I'm not sure.
In other words, could someone clarify how the DM-guided dives (which I guess are basically mandatory) and the traditional buddy pair mesh in this part of Hawaii?
I'm wondering if the missing diver would have had a buddy.
Thanks,

I my experience with multiple operators on the Big Island, yes (to guided dives without buddy pairs), no (to the buddy pair meshing -- the only pairs are folks who show up paired already).
I don't know if the missing diver had a buddy. My speculation would be no.
A typical dive charter for an operator with a big (not six-pack) boat on TBI looks like this. I don't know if this is similar to how IDH runs their charters, or Oahu diving generally.
* About 10-13 divers show up at the shop/dock. Two or three pairs/teams, usually, couples or parent/child. Anywhere from 1-3 DSD or folks taking OW, AOW, or (once, in my experience) rescue diver.
* Folks get a boat briefing, usually what the USCG wants you to know, plus what not to put in the marine head and where to put your stuff.
* Since there are between 8-10 certified divers, there are usually two DMs (who usually also hold instructor certificates).
* The op divides the divers based roughly on experience into two groups. The divers are told who their guide is.
* There's a site briefing that describes the underwater features, interesting Hawaiian endemic species, and the general dive plan. The plan is almost always to swim slowly toward the primary feature of the site while looking for interesting fish and invertebrates, turn around once someone gets to 1500 psi, swim slightly more quickly back toward the mooring line, and then explore around the bottom of the mooring line, sending divers up individually once they get to 700 psi (so they will, in theory, be on the boat with 500 psi).
* The divers splash individually or two at a time. When the entire group is in the water, the DM signs descend. Everyone descends.
* The dive plan is executed. The divers usually fan out behind the DM. When I'm a single diver, I usually swim in between the fanned out divers and the DM.
* The DM will ask for SPG readings from time to time. Divers are asked to signal 1500 or "turn" at that point.
* Eventually you are back under the boat and LOA.
* The DM signs "boat" and points. Diver signs "I see boat," then "3 minute safety stop, " then DM waves bye.
Nobody is watching you while you ascend to 15', or, while you are on the line doing your stop.
* As divers surface and swim to the ladder, the boat captain helps them onto the deck and out of their gear.
Also, for those not familiar with Hawaii, many sites, especially on the Big Island, have fixed moorings. The moorings consist of an anchor in lava rock at 40-60' with a line to a steel ball that float at 15'. There is a line from 15' to a surface bouy (usually an empty bleach bottle). The boat also hangs a 20' weighted descent line from the stern (but usuallly does not hang a stage).
When I was first certified I ascended and did my stop on the mooring line. I could easily see a diver ascending on the line all the way to the steel mooring ball, getting whacked in the head by the ball (which jumps around in the surge quite a bit), and getting knocked out.
