If I understand correctly, the problem posed was dealing with a steel cable
or a ski tow rope with steel cables in it. The British test had a variety of
prop protectors deal with what looked like electrical wires. After cutting
the first wire, they all jammed to varying degrees. If your prop(s) hit a
broken or discarded wire tow rope, you are up the creek unless the prop
itself knocks it away. Cutting such a wire would require a hacksaw (and much
energy) or a long-handled cutter, or an hydraulic cable cutter - and luck.
The extent to which any protector can do anything depends as much upon the
design of the cutter as it does the method of attaching it to the boat. It
is unlikely that anything will work other than a properly equipped and
experienced salvage diver.
