The X-Tream Angle Cam Fairlead is for the large cam cleat. It is most often used on the Flying Scot for the jib cleat when the sheet is led down to the seats. This allows for you to be able to control the sail from an aft position and still keep your deck clear of cleats for racing. Whether you daysail or race, this is a fine option.
