[PSUBS-MAILIST] gamma upgrades

[hank pronk via Personal_Submersibles]

Vance,
I like this rope because it is buoyant so it is always going straight up, also it never sinks into the prop on the surface.  It is not a tether really, it is a tow line for the flag since I don't have a surface boat.

 I don't like nylon
 for a surface tether because it soaks water over time and
 gets negative and heavy. Quarter inch polypropylene is
 neutral and has a 1400# breaking strength. We always used it
 unless there was a lift to do ( like long base acoustic
 transponders with a 300# bottom weight, for instance).

 am using 1/2 in yellow nylon rope that is buoyant and so far
 it is good but,,, the other day I hit a tree and dragged
 it.  When I was surfacing I noticed the buoy line was going
 down while I was going up.  That is why I attached it to
 the sample bag winch.  Clever yes? lol.
