I tell crew members to pretend they're electrified.

There is an interesting and long discussion on the cruising world forum about the high modulus fiber lifelines - basically spectra, dyneema, and or DuX brands.  The international sail racing federation apparently recommends 5mm diameter (10,000# breaking strength) Dyneema or DuX, or equivalent in non coated wire.

So no more lugging around a bunch of nasty, heavy wire coils in the the bilge or wasting prime locker space whilst cruising the seven seas. Some of the local race boats have dropped hundreds of pounds of weight out of their rigging by replacing all wire with this stuff.

So 5mm line needs 25 mm deadeye -1" eye.  Not a big deal... However, Looping around a pelican hook or other sharp radius reduces the breaking strength in half.  Down to 4,500#.  As that is the working load for lifting three bull moose off the ground, and the standard for pacific racing association life lines, I think I will  be staying with the fiber lines.

They seem to be sound excepting a couple of cracks in the plastic and having only been in fresh water.  I have been doing a little internet research and the current fashion seems to be stainless wire without the plastic covering, now required in some races such as the Lake Ontario 300 mile race and also there is a new type of rope which is non stretch, UV resistant and apparently very strong. The wire on boats I have seen is fairly skinny and looks like it would be very uncomfortable to handle.  Any opinions on the subject will be appreciated.
