I think if you do the math, you can see how the 1 hour limit is arrived at for the average boat. It takes 2 to 2.5 hours (depending on the weather, boat and destination ) to get to Catalina and back. Add in 3 one hour dives and 2 one hour surface intervals and you are at 9 to 10 hours. Assume an average of 20 minutes to get everyone in and out of the water on each dive (including repositioning the boat twice and anchoring 3 times) and you are at 10 to 11 hours. That leaves just one hour of slippage time if you are trying to run on an 11 or 12 hour schedule. My assumption of 10 minutes in and 10 minutes out per dive is probably very optimistic. I have been on boats where it seemed like it took 20 minutes just to get everyone in the water on the first dive.

Just as an aside, I am told that Reefseeker trips have a 30 minute dive time which they do announce. They run a lot of trips, so it must not be a problem for a lot of divers.
