I checked my mainsheet blocks yesterday and found that indeed, they have locking screws. There are actually two apposed locking screws. I did not have the correct screwdriver with me, so will lock them down next time. They are not Sheafer blocks, but some other USA brand starting with a "S."
Also while there I measured my halyards. It seems that the PO must have purchased a spool of 3/8" polyester double braid and just replaced everything with it. So the jib halyards bind in the mast sheaves, and the mainsheet is too stiff to "run" through the blocks. So on my Christmas list there will be New England Regatta Single Brade for the mainsheet and some Sta-Set X jib halyards. (The Catalina book specifies 5/16 halyards and 3/8 sheets) Anyone have a good way of binding new to old halyards such that I can pull the new ones through without loosing the end somewhere in the middle half up the mast?
