Yeah, when I did the Blackbeard cruise (looking back at my log), I did 18 dives.
I skipped the shark-feeding dive because I am morally opposed to that. And our last dive got blown out*. Otherwise, I could have gotten in 20 dives.
My total dive time was 1017 minutes, which works out to an average of 56.5 minutes per dive. 3 of those were deeper than 100 feet (just barely) and 1 was 95 feet. Even all those dives were more than 40 minutes.
I had 4 dives that were more than 70 minutes, with a longest of 82 minutes.
I can see that the main reason my per-dive average was so low was that we did a dive on the Smuggler's Plane and I only did 37 minutes on that. It was shallow and there really just was not much to see. The plane wreckage is not that big. And we did the Washing Machine. It's more of a ride than a dive. That was also only 37 minutes.
If there are Caribbean liveaboards that limit dive time to some arbitrary number, I would avoid booking with them.
* Generally, dives don't get blown out. The boat captain watches the weather and simply takes the boat to where the weather is good. But, on the last day, the only real option for the last dive site is one that is pretty close to the harbor where the boat docks. So, for that one, if the weather is bad, there's not really an option to go somewhere else, as the boat has a schedule to keep.
