Did the Nekton in Belize late Feb 2006. Excellent time. 27 dives in 6 days. Strongly recommended. This is a boat that was designed to dive from, looks a bit odd - kind of like a mini oil drilling platform, but is excellent to dive from. It would be a bit crowded with 32 divers on the dive deck, but as Footslogger says this would be unlikely - there were 18 divers on the boat for my trip. If I saw the deck was crowded I would simply wait 10 min until it cleared and then gear up. On the boat the entire upper deck is open area so lots and lots of room to spread around during the day. Dinner would be tight with a full boat, and the evening talks would also be crowded, other than that 32 people would just be more people to talk to.
