Backup plan is a Jersey Line, which is basically a spool of line you can attach to the wreck or structure and use to get to the surface or deco. depth. It keeps you from drifting away as you would without a line.

Sounds good but I don't think I explained well enough. We dive from pontoon boats in the Finger Lakes.

We are not on a wreck or a structure. We follow the anchor line down and check the anchor and then check depth before swimming into the current. More often than not we swim in one direction until someone hits 1500 psi or gets cold before turning around coming up to our anchors depth and returning. This has worked well for us. We have missed the boat and surfaced as much as 50 yards or so, but it has typically been an easy surface swim. One diver I go with will do a large square and everytime I am with him we have found his anchor line. I some how manage to get confused, simple math I struggle with in my head. Which is funny as I am a construction trade designer and I am forever doing math, I just need to write it out first...
