Yep, that's it! Brazilian Docks is what I remember Mike from Kyalami (PVD alumnus) telling me about.
I just called PVD to talk with them about the possibility of scheduling the boat for a long drift dive with twinset. I'm expecting a call back from Justin who schedules their technical dives. I'm diving Paradise Springs this weekend otherwise I'd be back with PVD to talk with Dean or Jason directly.
The two-three hour drift dive I mentioned above isn't really feasible without expanding beyond a plain vanilla AL80 twinset. I ran a hypothetical profile of 18m / 54ft with 36% backgas. I picked 18m because that's just deep enough to see everything even if the bottom drops to 24-28m. That gas and depth profile yields a few minutes shy of 90 minutes without a deco obligation with the AL80 twinset. Not very much a technical dive - really just an advanced drift dive but a super fun profile nonetheless! That's a pretty good stretch of sightseeing as long as the terrain is promising.
How many is a Brazilian?
But seriously, why is it called Brazilian docks?
I’ve been saying for years, that’d be the way to dive in these reefs with these currents, for those capable, I think it’s a much better option than going back to surface and back down again for a second dive.
In fact, some years ago I did an “investigative” dive to scout the area for that possibility, did it in Jupiter, started on the southern most reef, dropped down with the group and coordinated with the captain I’d stay down and scooter north, where the group would do the second dive on the northern most reef, half way through the dive, which was the combined time of the 2 single tank dives plus the surface interval, I realized I still had a long ways to go and went full power on my XK scooter, still didn’t make it to the group or the northern most reef.
I had a lot of the logistics worked out, since I was doing this from both the perspective of the diver as well as the boat/crew.
Anyway, can you please post here or message me if it happens, I’d be interested in doing it.
