Masthead sheave upgrade

Post by Mvallus » Sat Feb 10, 2018 6:20 pm

Has anyone upgraded their masthead sheaves from the original delrin (I think) sheave? I ordered the aluminum version from RigRite, but they are much heavier and I really do not want 10X more the weight aloft. This was the closest I could find via Harken: http://www.harken.com/productdetail.asp ... &taxid=396

Original: FM2C Masthead Sheave w/ 12mm ID - Aluminum: NG2-3AB12

I replaced mine with black delrin last year. Make sure to use stopper balls on the halyards to prevent shackles from damaging the sheaves.
