once again my ignorance to this media and not

using the correct subject matter. following

is an idea i have been thinking on a rescue device

used from surface craft for a poor diabled psub

What ya all think? still just basic planning

but I havnt' seen anything on this in the

archives. Are their any existing methods

been done already?

following is my idea of an emergency retrieval device to pull

disabled psub up.

Basically it consist of a float attached to a spool of small

diameter strong line (such as SPECTRA).

The float is released in an emergency and surfaces.

Top side on the tender is a cone shaped heavy lifting

device with a hole thru it to run the line from float.

The cone device is equiped with an appropriate

device to attach a wench and cable..

Then the cone is overboard and allowed to follow the

line down to and into the receptacle on sub.

the cone will penitrate thru hole and locked in when locking

fingers spring back above it. This will lock it in place and

the wench can than be used to bring the sub to surface.

The full details strengths and location etc have not been

worked out but I think it would work even if sub is at a fairly

steep anglel from vertical, the ring diameter would determine

what angles could be achieved, and naturally the superstructure

would have to be built to handle the load.

attached is simple sketch

once again I have not been able to attach the sketch

Appreciate any assistance on what I might not be doing right.\

to send attach or sketchs on note
