Agree with Alan on this one ... I use sailboat
line exclusively because of it's strength and longevity. Also use sailboat
'blocks' in place of hardware store 'pulleys'. They are about 2X or 3X the price
but they never rust or sieze up and the line never jumps the
sheave.

p.s. if you do visit a marine store make
sure to ask for line and not rope ;~)

Hi Martin, yes but the stuff I have can have as short a life as
4 years in
the sun. It does go brittle and breaks up.....what is worse in
that state it
leaves loads of little "needles" of plastic under the skin if
you handle it
without gloves. They dont seem to do any harm,
but.......
I have some 7mm pre-stretched polyester slated MARINE yacht
ropes, made by
British Ropes many years ago (1974). This is still doing
sterling service as
guying on my tower after more than 30 years. It has
darkened (usefull as it
"disappears" against the background of the trees)
and does have a greenish
look where it is supporting a colony of algae, but
it seems to have not lost
any of its strength. Its rated at about
1500pounds I think. I do use draw
rope for a light-weight mast but replace
it regularly. Unfortunately my old
salt mine doesnt have a stores any
more....we were able to make a personal
purchases of rate-book
items.
