A boat I am interested in will need new rigging. Forestay, backstay,
shrouds, and the hardware that goes with the wire. Turnbuckles, etc.

What process should I follow to replace the rigging? What supplier is the
best to deal with? What measurements etc do I need to know?

Is this a big job? From my reading, it doesn't seem to be. Mostly just get
the new and throw away the old. Am I missing something?

Also,,, life line? I will need new lifeline. Can I get this at the same
supplier?

Other equipment I am interested in and really don't know where to get;

A wind generator that attaches to the forward halyard. I've seen on in a
picture. My guess is it is a portable device that you put up when anchored.
I suppose you run a wire into the hatch or something. Any thoughts?

Also,,, an anchor windlass. One of the crank kind, not electric. Where
and who has this?
