Can't the socket be made to swivel and float upright.

Hello Jens. You certainly have a nice library.

The method of attachment shown in the above link is pretty nice. One possible problem may be that if the sub was on a wreck and there were additional entanglement hazards, the "two rope" system might increase the risk in getting the sub attached to a heavy lift line. The "pin and socket" used at JSL seems like a foolproof method. Here's a quick sketch for the folks who didn't get to see it at Harbor Branch.

Although just about ANY mechanism is subject to failure for one reason or another, this one seems good.

The pin follows the buoy line down and the socket is just a tube with a "collar" so the expanding "ears" catch on the inside. The pin was very heavy and it appeared to be able to enter the socket at an angle if the sub was not sitting level. Not sure how much angle would be accepted. The missile shaped pin should be able to maneuver through most obstructions, and "center-up" on the socket at a pretty good angle.
