[Public-List] Mast up! No halyards~!

Good morning Jeff -

The mast column is no problem - it's massively over built for the loads our
boats put on them with regard to compression.  They'll take thousands of
pounds.   The issue is the integrity of your halyards and blocks - those are
the weak link in the system.  I would hesitate to trust a forty odd year old
nicropress or an old block.

For your immediate issue rigging your halyards, I'd say the safest way to do
this with the mast in place is to use the mast crane to hoist somebody up to
the masthead.  That person should have a sailor's safety harness on so that
once in place they can clip onto the mast, thus providing a redundancy for
safety.  A problem you may encounter is your marina, who probably doesn't
have a human lift rating for their crane.

I think I have already related my story of getting hauled up to the masthead
of a Fife P class boat when I was doing itinerante rigging only to discover
that the block I was on had opened; all that was holding the sheave on the
pin was the remains of the burr that was once the riveted end holding the
absent strap.... I started carrying binoculars in my kit so that I could
take a hard look at the masthead before going up, and then always requested
two halyards on my bosun's chair.

You'll probably have to drop the stick and rig the halyards horizontal.
That should only take a few minutes each way so is not really much more
bother than sending a man up.
