What makes Roatan unique in the Mar Caribe?
Shallow, protected, Sunlit. No more or less to it.
If the weather is dead flat calm, return atop the CCV wall. Not at 25', nope....I mean in 5 feet. I have not found a better and more intact Caribbean Coral example. It is startling.
Different depths, not hurrying. These drop off dives, essentially dive #2 and #4... You get those 2 per day times 4.5 days, so 9 in total...you get "the same dive" only four times in total.
Hydraulics, which us what you're talking about, are a mathematical fact. I've really studied that Front Yard very hard, I'm the guy who painted that map on the big round table on the bar porch. Look at the geography. When the wind picks up, that basin overflows with surge. If the DM says no, you should agree. Suffice to say, if it's 6' plus out of the SE, you're going to be better off in the bar. It would be akin to landing a J3 in a 15mph sidewind. Doable but why bother?
Surge, per se, is a shallow water phenomenon. Current? Roatan has very little current at the commonly dived sites, the leading exception is Cara a Cara, the Shark Dive, but they rig the boats with proper lines, easy breezy.
Visibility is simply not what the Bay islands is known for. You figured out that macro is the name if the game. How much viz did you need exactly to see something the size of a Seahorse... Or smaller?
I'm thinking that you're way past most divers in learned perceptual abilities. The majority of divers are still gawking at and seeking "larger fish". Along their quest, they like to see wrecks (not understanding that wrecks are more than romantic rusty iron), pretty corals, and are subliminally attracted to variations in geographical reef architecture. I believe that viz (aka crystal clear gin visibility) is in that category. It is highly overrated. Want viz in the Caribbean? As far as accessible for easy travel, that would be Cayman, but we all know that.
In my experience and as stated in "the standard bible" by Paul Humaan of Caribbean Reef Coral ID, Roatan and the Bay Islands have to widest array and most plentiful concentration of Soft Corals. Paul was specifically referencing the protected South shallows you visited.
Again, your post was brilliant.
Thank you for mentioning the shallow depths, I forgot to mention that additional advantage of this part of Roatan. More ambient light and less gas consumption and nitrogen absorption. More critters at the shallow tops (20-30ish feet) of the walls, in my experience. Look at the wide-angle reef shots on my Instagram page, and you can see how shallow I often was, capturing the texture of the surface and some sunbursts in the background of the sea fans and the elkhorn coral.
Some have cited this shallow wall topography as a reason why they found Little Cayman diving to be so great. This part of Roatan had comparable depth/topography to many of its walls, but much denser reef growth and more critters, albeit of the smaller varieties. I would also agree that great visibility is overrated. What good is 100 foot visibility if it only highlights how sparse the reefs are, as in some parts of the Cayman Islands?
