Here are the lengths of lines for a 470 tall rig. If you have a standard rig the only lines that are different are the halyards, they are 10'
My jib furling line will sound long, but I rig it as follows:
The furling line comes from the 3100 furler up forward, down the port side of the boat, back past the sheet turning block to the rail where I
have attached a block to turn it back forward. At this point it goes through a rope clutch, from there we take it across the boat to the electric winch. This was set up with a 135% Genoa, a 155% Genoa would require additional
footage. I only use Sta-Set X (less stretchy)for the halyards, By using the cheaper Sta-Set for everything else I don't mind replacing the line as much when it gets ugly.
