Just for thought:
Upline with sufficient but not exceessive scope, redundant surface =
floats, and bottom chain with snap/hook. Down rig with divers is dropped =
ahead of wreck to drift into wreck (one diver in team drops with the =
chain end). On end of dive last divers detach chain from wreck and toss =
into sand. Proceed up line. Now the line is drifting with the current =
with a slight bottom drag from the chain. No flag flying. No issues. =
Relaxing. The boat is always free to maneuver. If too crowded on line, =
you can hover alongside or pop a lift bag nearby. Will still drift the =
same as main upline with a slight backpeddle to compensate for chain =
drag on main upline. The captain on the boat knows where everyone is; =
can drop a safety diver on you if appropriate and recover used stages. =
Its a piece of cake and works well in raging currents like we can have =
in the gulf stream (and with close to shore shipping as well). A slight =
mod on deep stuff (350+) though, and you need a captain with a clue.

My two cents,
Doug
