I didn't find Maracaibo challenging, currents were mild. But we went deep and my very conservative Suunto made me do 22 minutes of deco. That might pose an issue for a newbie low on air.I have gone to Maracaibo a few times with Aldora and the dive was not planned nor did it become a deco dive. That it was a non-deco dive even with my very conservative Suunto dive computers means that it was even further from deco for most everyone else.
They seems to start out at some arch formation then head shallower to a nice area. Obviously someone could go as deep as they choose at that site but that applies to many sites on Cozumel, including Palancar.
It is a nice dive and not that challenging in my opinion (yes I may be wrong). Barracuda would rank higher on the challenge scale.
It does make sense that there would be a shallower area, it's probably just not very well publicized because the few boats that do go that far south are probably only a "special" trip to go deep. I can accept that answer, unless we hear otherwise from the OP and I'll bet he's afraid to open his mouth again. Dave probably ripped him a new one for implying online that Aldora took him to an "expert" dive site
And if I hear any other newbie reports saying they went through Devil's Throat on their first dive, I reserve the right to again "raise my eyebrows" and question it. After all, that's what we're here for. Can't just talk about restaurants and CO analyzers all day.
Barracuda is the goal for my June trip. I've never gone north.
