The best I've seen for this kind of thing is Spectra 12 from Novabraid--a hollow braided 12 strand rope with breaking strengths comparable to wire rope. The 1/8" diameter rope, for instance, has a breaking strength of 1800 pounds. Anyone who checked the JSL emergency buoy reel will have seen about a half mile of that stuff on a spool between the pilot's sphere and the diving compartment. It is seriously strong, easy to handle, and resistant to virtually everything, apparently (sun, salt water, heat, and so on). Great stuff.</font>

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.<br>

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

Vance, <br>
Great idea, I<br>

it is good but,,, the other day I hit a tree and dragged<br>
it. When I was surfacing I noticed the buoy line was going<br>
down while I was going up. That is why I attached it to<br>
the sample bag winch. Clever yes? lol.<br>
