Yeah, I think the captain was under the impression that most of the boat didn't want to continue. Technically, the 4 who didn't want to go again, didn't do the first dive either. They jumped in on the first and within 5 minutes were back on the surface. Others may have come up early as well. We were the last 2 to surface and the only 2 to make it to the Mizpah. I knew where it was, directly north. It's a pretty easy jump. At the end of the day, he saw that most of the boat wanted to do the second dive, so he set what he considered safe boundaries (don't leave the Mizpah) and we did the second dive.Sounds like the biggest issue was the inexperienced, anxious divers on the boat and not the viz. I've done dives with PV before when 10' viz was the best we could find. We all gladly did 2 dives because it's better than not diving at all. I used to dive in pea soup rock quarries in Indiana in the winter in 45 degree water, so ANY dive in South Florida is worth doing to me!!
