Your wife, Hank. Now there's a good option, does she know how
to operate the ballast valves?
If the cable started going slack you would know the sub was
coming up & could get out of the way. just keep tension on the line
with the boat & as long as there is an angle on the cable you won't get
hit.

If I have my steel barge above Gamma there could be a very serious collision.  The other option is to forget the barge and send Gamma down with a rope attached as a locator and a way to slide a cable down to retrieve it.  The rope only needs a rubber float to locate it.  I would put a second auto pilot in that relies on a battery going dead to make it surface with a separate hp source.

>> The other option is use the auto pilot from Alec without the water sensor and have the barge over Gamma with the cable between.  Then there is a safety if the cable fell off or what ever, and if the sub fills with water I can winch it up.
