As I read the Adventures in diving manual something about it was familiar but I couldnt put my finger on it. Later it came to me
the Boy Scouts! Its like earning merit badges.
A good analogy. It is a bit like that. But, then again much of what is done in education in general is like that - to get a degree you must complete X courses/credit hours, including Y course in a major field, along with certain required general courses that touch on whatever the particular college / university thinks are politically, culturally, or socially redeeming in value. The average undergraduate student does not have to actually learn much of anything, just check the boxes.
The Nav and Search and Recovery dives sound boring. The cove where were going to do the skills is a mud / sand bottom. Its probably easier to find an object, but not much to see.
To a certain extent, the AOW course is tuned to the level of experience of the usual student diver. With over 1000 dives, you are NOT the usual and customary diver in an AOW course. The instructor working with 6 divers each with less than 25 dives on one hand, and you on the other, would probably be challenged to come up with a meaningful common educational experience for the seven of you, WHICH CONFORMED TO STANDARDS.
I can appreciate why you are adding the cert - more than a few charter boats require it for certain deeper wreck dives. But, I agree with Jim and Andy, you would probably be better served by an essentially private course, where you could articulate YOUR learning goals and work with a qualified instructor to meet them. As Jim points out, you can make the nav dive interesting and challenging, even though the PADI standards are limited - e.g. the recommended navigation square side lengths are (only) 100 feet. But, in that case, 'limited' does not need to be 'limiting', and doing a square with a 200 yard side is acceptable. For the Deep Dive, in contrast, the maximum depth is 100 ft, which may be 'limiting', where the student diver has already been deeper, on numerous dives.
Out of curiosity, other than getting the cert as the charter admission ticket, what specific learninjg would YOU like to get out of the course?
