I am reinstalling a Furlex 64A roller furler. I am confused about how long to make the forestay. According to the data I have it should be 9.165m or 30ft 7/8 inches, but this is LONGER than the standard C25 forestay. Seems to me it should be shorter, to allow for all of the fittings. Have any of you ever installed one of these furlers and do you know how long the forestay should be? Thanks, A. K. Moser
