RE: [PSUBS-MAILIST] Distress Buoy

["Jon Wallace" <jon@psubs.org>]

Alec,

Most of what I've read from the ROV world indicates that regular coax cable
gets stiff in cold water which makes it difficult to work with.  So even if
space was not an issue, I wonder whether the line would have fed out from
the spool efficiently enough to make it realistic.

This discussion sounds like a potential "chapter" in any operation
guidelines that we might eventually publish.  I'm wondering if this is an
area that you'd be interested in pursuing further Alec and make some
recommendations on.  For example,
 1) Is an antenna buoy feasible?
 2) If so, what materials are used?

Assuming materials are not an issue, what classes of distress buoys can we
identify as practical?

Jon
