We had garhauer modify some of their sheaves for Perception's 3 forward halyards, as their stock were just slightly too wide, the aft 2 the stock fit fine. One benefit is the new sheaves do not rub the aluminum mast head casting. The sheaves I removed had chef sharp knife edges from rubbing on the casting.
To get the correct width, I sent the old sheaves to garhauer. Our halyards now have ball bearing blocks and sheaves at all turning points .... only noticeable friction is now from the sheet stoppers, and mast/headstay track.

I had planned to but a track slider system, but didn't; I seldom use the halyard winch and the main drops when the halyard is released. The boat came from a saltwater environment and we are in freshwater, for whatever that's worth. good luck with it! Richard S/V Bushmark4; 1985 C&C 37 CB; Ohio River, Mile 596 Richard N.

I could not find listers' advice/experience about changing SIZE of halyard line from current wire/rope to Dyneema blend (looking at 3/8 Samson MLX). The halyard sheaves appear to have enough width to handle 3/8 line; and understand the sheaves need to be smooth to avoid chafe, which they appear to be. Seems 3/8 MLX would have enough load capacity for each of the 3 halyards on my 35-3. Or...is there guidance to go up to a 7/16? Anyone with opinion?
