Comments Water temp was warmer than expected - 85 on most dives, a few dives had a thermocline deep (80-100') that dropped the temp to 80. Most everyone was diving a 3mm full suit.

The group of 21 divers was split between two pangas with each typically going to different sites and then they'd swap so that everyone got to the same sites. At one site a couple of times both pangas went but separated by 30 minutes which worked fine.

My group was horribly unlucky compared to the other group - they had much closer encounters with hammerheads, saw a tiger shark multiple time, allegedly saw a baby humpback. My group had a couple of divers who wouldn't hang on the rocks at the cleaning station or would chase after sharks when they'd show up and I think that went a long way towards the sharks keeping their distance from my group. There were some confrontations with one couple who would do that and the captain and cruise director talked to them but it didn't seem to help.

Panga rides were 5-15 minutes, all gear is kept on the pangas and you'd gear up once you got to the site. You'd backroll in negatively buoyant and head for the bottom to wait on the rest of the group. I often was the first one in and it would typically take 10-15 minutes for the rest of the group to get in and get to depth. I started hanging out shallower because I'd run low on air if I went to 80-100' waiting for the group. The divemaster was last in and then you'd typically hang out deep at a cleaning station waiting for something to arrive. If after 5-10 minutes nothing showed up we'd start swimming around the site and quite often would then swim out into the blue around 50-60' and see what we'd run across. The panga followed but they typically wanted the divemaster to be first on the panga to help people back on board with the panga driver and he typically would surface around 55 minutes.

The longer panga rides were a beating if you were sitting near the front. Choppy seas and the throttle being wide open is going to result in some hard slaps against the water in spite of the best intentions of the driver to recognize the waves and chop the throttle to avoid that.

With the longer panga rides, it taking 20 minutes to get everyone geared up and to the bottom, then taking another 15 minutes to get everyone out of the ... Subscribe to get the full story. For Subscribers Only  Active subscribers continue reading here
