[quote=windwardde]Shroud extenders are typical on Supercats, in particular.
They have an extra wire on lower part of the shroud that is connected to a "caming device" similar to a miniature chain tightener for heavy equipment chain tighteners.
Once you have flipped and loosened your sheets, you flip the cam open and it adds extra length to the shroud, allowing the mast to be pulled further out of water before your weight and moment arm kicks in.
The point made earlier re mast ball is that without having the mast ball captured, you could pull the mast out of the ball and now, not only are you flipped, but you are demasted.
Supercats do have a mast ball captured if you leave the pin in.[/quote]
