I'm looking at an O'Day 25 as my first boat. I'm buying it from a guy who never really got into sailing so couldn't answer many questions. I noticed that both the main and jib halyards are steel cables going through the pullys on top of the mast and then are tied to lines making up the working end. I haven't sailed many boats but it seems that the halyards have been a continuous line. Does this seem normal?
