Online shopping often offers me the opportunity to read fairly objective user reviews. I've stood in Walmart doing this on my iPhone with intent to buy something in front of me if it checks out.
Wookie, I'm still trying to get a better handle on your target customer. From what I've seen, dive boat op.s offer a continuum of service & target demographic, such as...
1.) Aim for newbies; guide in the water, maybe one in the rear watching for strays, guide periodically signals divers to report their remaining gas pressure, etc... Catering to cruise ship divers, protecting the sheep from Darwin, enabling people who shouldn't be certified, people have varied reactions to this practice, but it's there.
Not your demographic.
2.) Valet service - this is what I see mentioned when I read about Aldora, Little Cayman Beach Resort and some other places. While much of the customer base is seasoned, there's an emphasis on a 'luxury' experience; they set your gear up, break it down, maybe rinse it; you just show up and dive.
Not your preferred business model I take it.
3.) Middle-of-the-Road service - boat takes you out, gives a briefing, guides may just lead the group (e.g.: Jupiter Dive Center on hot drop drift dives), cost extra or not be offered, set up and break down your own gear, and while there may be a time to be back on the boat, it's less likely anybody checks your dive computer (unless it's squawking) after the dive - not much 'monitoring' aside from making sure everybody's back on the boat. My impression of Jupiter, FL and Morehead City, NC.
4.) Closer to Taxi Service - like 3.), but you can solo dive without a cert., how many dives you do is up to you (long as you don't hold the boat up), what's a guide? My impression of California live-aboard diving from my one trip & what others write.
Tell us more about the demographic you want or need (not just your perfect fantasy customer). Are they doing on-the-fly light deco., deep diving on air, expert navigators, what? Are you just after more self-sufficient, low maintenance seasoned intermediate recreational divers?
And what diving have you offered, or do you want to offer, that requires that level of diver?
Or is this about dive boats that don't have ensuite heads?
