Stus-List Masthead sheaves C&C 37+

[Josh Muckley via CnC-List]

I have a new problem for the collective wisdom.

I'm getting the masthead sheaves re-made by Ed at Zephyrwerks.  He made my
boom end sheaves 2 years ago and did a great job.  I have a 1/2" wide
sheave box for 3 sheaves.  He cut them with a slight relief and cut the
groove for a 1/2" line.  I had told him that I simply didn't want to
needlessly limit my options in the future despite only using 5/16ths or
3/8ths for the reefing lines.

Now 2 years later I'm in a similar situation except the masthead sheave
boxes are 5/8ths wide.  I can't exactly recall but I believe that I'm
running 3/8ths halyards.  When I talked to Ed he advised that he would like
to cut the groove to match the line which is on the boat. 3/8ths. But also
stated that he could cut it however I desired. It seems unnecessarily
limiting of my options in the future to cut a 3/8ths groove. It is far
easier to run 3/8ths on a 1/2 inch groove than 1/2 inch on a 3/8ths groom.
The original sheaves were v-grooves and would accommodate anything from 1/4
inch wire rope up to 1/2 or even 9/16ths line.  And we haven't even talked
about the added thickness of a core to core eye splice.

Anybody want to share their thoughts?

I've been getting some good feedback on the torqing video I posted on
YouTube, so I told my wife.  She stopped dead in her tracks and I had to
quickly clarify torque-ing not twerking!  Haha 😂

Re: Stus-List Masthead sheaves C&C 37+

[Ron Ricci via CnC-List]

Josh,

 

My sheaves seemed to be original as I could not find anything from the FO 
indicating they had ever been replaced. Patriot’s mast was out last winter and 
my rigger said her sheaves were fine.  They did not have a groove for wire 
rope. 

 

I think my halyards are 7/16 with a  1/2” groove.  Each winter, I pull 3/8” 
messenger lines in place of the halyards.  The extra space makes it easy to 
connect the messenger to the reeving eye on the halyard.  I’d suggest keeping 
the 1/2" groove.

 

Just my thoughts,

Ron

I got mine several years ago from the original mast manufacturer In Michigan.  
Offshore Spars perhaps?   Perfect for for all the masthead sheaves.

Re: Stus-List Masthead sheaves C&C 37+

[Jake Brodersen via CnC-List]

Josh,

 

3/8” should be plenty big for your halyards.  ½” is certainly overkill.  Why 
not split the difference and go with 7/16”?  A slightly larger sheave should 
create any problems.  As strong as halyards are these days, some would argue 
that 3/8” might be a bit too large.  I’m sure your halyard stoppers are driving 
the decision as well.  Going too small can create problems.

Re: Stus-List Masthead sheaves C&C 37+

[Josh Muckley via CnC-List]

Halyard stopper?  What's that?  Haha, no really what's that?  Stopper
balls?  Or jammers?

You're right though 3/8ths is almost too small for my winches.  So smaller
is pretty unlikely.  But bigger might be nice, particularly if it becomes
necessary to run the taper of a core to core eye splice.

The 3/8ths sta-set I have for my spin halyard is almost too small at ~5000
lbs break strength.  I really like to make sure my lifting rigging is
sufficient for climbing standards.

I guess my question is, is there any disadvantage to running smaller line
in a big sheave.

Josh
