Bill1188:
Time to switch out the old wire to rope jib halyard. Too cold for me to go measure anything in Michigan. What is length I need and best diameter? Pearson 323.

Dolce_Vita:
When I converted mine, I used 3/8" VPC.  Strength wise, you could go smaller, but it would be difficult to handle.  And the hybrid VPC is a good compromise between hi-tech/low-stretch and cost.

Don't remember the exact length I used, but with a mast height of 45', you're already looking at 90'.  I'd round it up to an even 100' to allow for plenty of tail.

Be sure and replace the sheaves while you're at it.  Zephyrwerks (https://www.zephyrwerks.com/) will build custom delryn sheaves with bronze bushings to your exact measurements for a reasonable price. 

Alma:
So you still have those measurements Ed?

I'm looking at replacing my main halyard and on-the-fence about wire/rope or synthetic.

If I could get new sheeves in anticipation I may switch to lose weight aloft.

Thanks.

Dolce_Vita:
Took a while to dig them out.  Here's what I submitted on their form:

Question    Answer
Type of Boat (i.e. "Baltic40")    Pearson 323
Application (i.e. masthead, boom, etc.)    Masthead, external halyards
How did you find us?    Referral by Geoff Kloster
New sheave diameter    2.505 "
New sheave width    .493
Pin diameter    .370
Line size    3/8
Wire size (if applicable)    
Grooved for    Rope
Groove depth    5/32"
Quantity this size    4
Quantity and size of pins    
Comments    These are for a conversion from wire/rope halyards to all-rope. I'm a bit concerned about the side clearance of the sheaves because it's already very close, and the masthead is getting repainted with 3 coats of Awlgrip. My slot measurements of the bare metal masthead are:
Fwd Port Bot .554"
Fwd Port Top Not accessible to measure
Fwd Stbd Bot .527"
Fwd Stbd Top .568"
Aft Port Bot .555"
Aft Port Top .549
Aft Stbd Bot .533
Aft Stbd Top .549
   
          
 



 

Alma:
Thanks Ed. As detailed and accurate as ever.

Is there any reason to believe mine would be any different?

Would you order based on these dimensions?
