Nemrod, Why not buy a "cheap" kayak to paddle out there? At least to the mooring balls are and then swim the rest of the way? Or is the current to strong to get back?
acteg, I was there yesterday. First time there, we dove from Datura. the vis was pretty bad. Real bad at first but as we got out closer to the reef it opened up to maybe 30ft at best. I did see a lot of critters but no Lobster, sharks or turtles. Of course I was also having issues with a new mask fogging up constantly so I may have had a 15ft great white in front of my face and just not seen him. haha.
I have used my kayak there in the past, it is a superb kayak dive site and that is the best way to get to that area. But, this trip down I flew instead of driving so I could not get the kayak into the carry on much as I tried.
I am not sure I understand why only use the kayak to the mooring balls and then swim the rest of the way, if I had a kayak I would go all the way on the yak. Yeah, there could be current there but if I can swim it then a kayak would have no issue. Yes, there can be signficant current on the deep break. You might want to add a cell phone in a waterproof bag, depends on how good a swimmer you are

Hey, just because I can do something or have done something do not take it as a recommendation for everyone to do the same, all I am saying is that it is possible. Evaluate YOUR capabilities and the sea state and conditions and YOU make the decision. I, have no difficulty swimming that distance or being in the water that long. As long as I am not cold, I am good to go and I have gone much further than that.
More than once dive boats have tried to pick me up thinking I am lost from another boat. Sure, I will take a ride, out, not in, lol

. Well, OK, in also if I am done diving, but what fun is that?
