My wife and I both have excellent bouyancy skills and never touch the reef. Really. Frankly, neither of us have any intention of touching anything underwater besides a decent/ascent line.
Now, with that said, we have both at some time or another been stung by marine invertibrates in the water column. I was stung by a sea wasp on the back of my leg in Aruba while snorkling while my wife got some sea lice (baby jellyfish) while swimming in the BVIs. Consequently we take the term "exposure suit" quite seriously and never dive without a full wetsuit, booties and, yes, gloves. The gloves makes sense to me for another reason as one is often called upon to decend or ascend on a mooring line, invariable encrusted with some quantity of fire coral.
We are going to GC for a vacation soon and, while I know that gloves are "not permitted," I am wondering just how strictly the dive ops there enforce this?
If you pull them out during your predive, you'll be told to leave them behind.
I have heard of some individuals who will keep them in a BC pocket and put them on only
if they're going to touch a crusty mooring line ... even then, it is probably wise to put the gloves back in a pocket when leaving the line (before reboarding)...in any case, its probably smarter (and better in several ways) to just carry a Jon line with hook instead if you plan on routinely using mooring lines - - I've found that for the occasional desire to hold on that a careful hand placement usually suffices ... and if it is nasty, then I'll hook my (wetsuit protected) elbow around the line instead.
For floating stinging stuff, I'd say that in the Caymans that's generally only going to be a meaningful concern on night dives when the sea wasps happen to be out. Of course,
even when the Wasps are really bad, they usually manifest as a surface layer, which you can address by purging your 2nd Stage to "blow a clean hole" to move them away long enough for you to ascend the last 15ft to the surface.
For those with legitimate health issues (e.g., Raynaud's or extreme allergic reactions to marine life stings, etc.) you can request an exemption for the duration of your trip. The exemption is issued by the Cayman Marine Conservation Board. You will need a letter from your physician. Your dive shop should be able to assist with this, and it's advisable to make your request several weeks prior to your trip.
Good to know at least who the relevant office is, since that info's not clearly documented on Cayman websites, just like how it isn't all that easy to find where the rule is listed ... it is not documented at all through CITA (who still keeps their "Safety Code" not available to the public by that name).
Of course, in trying to locate a contact email address, the
Govt page that popped up on my search is from 2001 ... only a mere ten years out of date!
