Hello Columbia sailers... My boat is a 1966 C23 Contender which I have owned for just under a year. Her previous owner spent more time sailing than maintaining, for which I will not fault him. I'm putting her straight now, hoping to have many more years with her, but I need some help.... 1) The boom's gooseneck fitting has corroded at the upper eyelet and I'm wondering if it's possible to a)repair, b) find another. I know a machinist who can make one out of solid billet. If anyone has a recommedation for me, I'd appreciate some help on this matter. 2) I've dropped the mast to change electrics & rigging. The main halyard is cable/dacron and the main halyard sheave, which is set up for cable, is original and looks worn. Does anyone have experience with changing cable halyards to rope halyards and the implications to the sheave? I know that if I change the halyard to full dacron, the sheave will have to be changed to accept it. I need some help deciding if I should a) replace the halyard and sheave, maintaining the cable/dacron setup, b) go with a purely dacron halyard and change the sheave accordingly...will a larger sheave fit into the trapeze? Any opinions would be appreciated. Thanks, Ron
