This
is probably a dumb idea and for sure it would not work in water with low
visibility - but, assuming that you have very good visibility, very clear water,
what if you shot a laser directly up from your sub ? how bad does a laser
diffuse in water? It seems like you could do that and you might be able to
detect the light on the surface using binoculars. During the day it would
probably be difficult, but at night it might be possible.

Comms and a pinger sound about right (sorry for
the pun!!). Redundant sure works. Lines are dead simple but can be
a hazard. I would have to assume you're staying within scuba limits
because of your backup divers?
It's amazing that what seems so logical on
paper is, in reality, a complete bust in the field.
Keep us informed about the OTS
items.

on the line could work but I think that I am just going to jettison the
safety line and buoy. I have a pinger attached to the boat so finding
the boat should not be an issue. What I really need on the
boat is the underwater comms. Dan Lance put me on to some really good
equipment from OTS that I am looking at.

Hi,
Cliff - nice to see the progress on your sub. That is one beautiful
boat!!
I have
a thought about your lines. Since you're in really poor vis would it
be prudent to keep your locating line, but, keep it buoyed by intermittent
floats along the rope? This is a buoy system we use up here that keeps
lines off the bottom. Whether it would be practical as far as your
intakes are concerned is another matter, but, it may just save your
bacon.
