Jerr, Wow,thanks for the detailed information!
My sheaves are original equipment and are "u" shaped for the rope with an in-cut smaller diameter "u" track for the wire. If I go with all-rope, my original C&C manual describes 3/8 inch rope for the wire-to-rope, so can I assume that i can still use 3/8 inch rope, and leave the original sheave alone? (other than the modifications with teflon washers etc.)
By the way: any suggestions for 3/8 line
? I see sta-set, stay-set x, lamson, and so on; mentioned with varying degrees of endorsements. The boat is just for cruising, so all i want is to set it and forget it when I am trying to sail and watch my 4 year old at the same time.
