Disclaimer: I usually stick to lurking in these sorts of threads and I don't have any real experience in a 3-man team under water. However, this debate parallels current debate in the fire service and there are some interesting comparisons to be made.
A two man team offers the simplicity of tracking only one other person. In cases of impaired visibility, communications and sound keeping track of two others is more difficult, requiring a higher degree of awareness on the part of all 3 persons. Given the number of reported "bad buddies" who can't keep track of one other person, this skill level may well be beyond many recreational divers.
However, if two people are working on a task they tend to be pre-occupied with that task, and not on other surroundings. If the surroundings are potentially hazardous then the benefit to having a third person focused on those hazards and the safety of the other two outweighs the liabilities. In my experience, this means that the person with the greatest skill and experience is usually following, directing the others from a position where the whole picture can be readily observed. A side effect is that the others must keep an eye on the "leader" behind them for direction.
Some of the above posts make reference to all members sharing the same mindset. I think that is absolutely essential. While it is pretty much a given in firefighting (eg: a particular team is assigned to a particular task) it may not be the case in a tourist situation were there is no specific task or special hazards and each individual is just there to "look around". I have never done any penetration or other technical diving, but I suspect the circumstances were 3 man SCUBA teams are of value would be found in those disciplines more than rec diving. In those cases there is a focus or task to be accomplished, there are special hazards to be avoided, and the skill, experience and concentration of the individuals is above average.
I offer the following suggestion for discussion: Perhaps the person in charge of a 3 man team should "lead from behind" so the other two are always within his/her field of vision. Having been explained during the pre-dive briefing, the other two will know to continually look back at the leader for direction. In the event that one diver obviously forgot the briefing, the leader will detect any deviation immediately and take corrective action. Who knows, perhaps experiencing such a team approach may serve to improve some people's buddy skills too.
Any thoughts?
