I just got home late last night after staying seven nights at Caribe Blu and diving with Blue Angel. Blue Angel is an excellent dive operation for what they charge. I have only been on the fast boats and they do motor along at a good clip to the sites (put your towel under your butt). The DMs all have their own particular styles but they try to match diver's abilities on the boats and the divers mostly pick the sites that are done. Ramon especially has a democratic election on the boat to decide where to go. If you want to do Devils Throat you have to be an advanced experienced diver and everyone on the boat has to want to do it. If you want to do Maricaibo (sp?) or Barracuda you have to be advanced, experienced, have dove with them enough to prove it, and arrange with enough other divers in advance to make it worth their while to do the trip. If you want to do the cenotes on the mainland, which I highly recommend, speak to Matt (Mateo) Moran in advance. He is an experienced and excellent cave guide and will take 2 to 4 divers on the trip. If you have not done this try to do the Dos Ojos cenote, it is indescribable - 300 foot plus visibility and an strange beauty you have to experience if you are a capable diver.
The temp was 78 degrees on every dive except the cenote which will be a few degrees colder ( depending on if it is all fresh water or layered fresh over salt water).
