NC Wreck Diver
Contributor
This is what we did on my boat. I agree with everyone who posted 'get a third person.' Here is how we did it. Diver 1 & 2 do a dive. Diver 3 stays on the boat. After a SIT time, diver 1 & 3 dive, diver 2 stays on the boat. After another SIT time, diver 2 & 3 do a dive. Diver 1 stays on the boat. With Nitrox, this can work out quite well, since SIT times generally not as long, and you can easily get at least two dives each.
Also, we always tied the hook (grapling) into the wreck with sisal rope after fouling the chain through the wreck a few times. This always gave us a sense of security that the hook would stay put. A cross wreck line tied into the anchor line is a must. Visibility off NJ, DE & MD is normally limited, so a line is worth it. Just spool it up and take it topside after your dive day is done.
We have no coral reefs in our area. So all we dive is wrecks (which is our choice anyway). So, I have no real experience in anchoring into a fragile coral reef. Safe diving to you.
