[C38] Halyards

[les]

We have been using Sta-Set X on JACE and I like it.  No wire at all.  

I don't remember the numbers, but Sta-Set X compares favorably with
wire.  And no rope to wire splice.  

Some folks run the wire to rope splice around their winch and end up
with all wire.  If you do that, you will surely eat up the drum on the
winch, and you will make the splice weaker as running it around the drum
will stress it in ways it will not experience other than over the
sheaves, only if you leave it on the sheaves will it be bad for it.  At
the lowest point of the lift, the splice has little weight on it as it
goes over the sheaves. 

If you are looking at technora or more sophisticated lines, read their
flex ratings carefully.  The carbon core lines cannot be flexed too far
or they will break the internal strength strands, that is why the
America's Cup yachts have those large winch drums.

The sheaves can corrode and lock up on the masthead.  That is what
causes some of the failures of halyards.  The sheave chafing adds to
that problem.

What our boats don't consume in fuel and oil they consume in sweat.
