Hello, I am planning on replacing my main halyard on my Catalina 27 (standard rig). I believe the sheave & winch are the original set up, the current halyard is currently made of about 30' of steel cable with a snap shackle on the cable end and about 50' of what looks like a 3/8 line attached to a an eye on the cable. As the eye on the cable is crimped with and the eye being somewhat large, the 3/8 line won't fit through the sheave.
I am wondering if a 3/8 line would fit through the sheave? Do I need cable and line? I was looking at buying this replacement but I am wondering now how I will be feeding it through the sheave? http://www.defender.com/product.jsp?path=-1|118|75227|753823&id=75388 Any insight welcome:-) -- Stephan
