[Alberg30] Main Halyard

[Bill Blevins]

If you have a really old mast and the original brown/maroon fiber/mesh-coated sheave, you will have to replace it if you want to widen the groove to accomodate larger rope haylards.

3/8" halyard MAY fit on it  "as is" though. (Probably not "in" the groove.)

I'm not very good with the technical terms. I'll post a link to a photo of an old sheave tomorrow.
