[quote=shortyfox][quote]It has a white ball on top of the middle of front beam - is that the captive system people talk about? If so, I guess that is a modification done after manufacture right.[/quote]
[quote]Are diamond wires and shroud wires the same?[/quote]
Not sure about one as old as yours but all the Nacras I've seen use a nylon ball for the mast to rotate on. When it starts to flatten out on top, replace it. It's threaded, don't overtighten! A pin holds the mast step captive to the ball and the mast must always be turned ninety degrees when raising or lowering.
Shrouds are the wires that hold the mast up. The front one is usually referred to as the headstay or forestay. The diamond wires are part of the mast and are used to limit mast bend.[/quote]
