I don't have the measurements... and my jib is furled on my boat... and to measure I'd have to drop the mast.... don't plan on doing that until winter....
but yeah, it's worth it to have a jib.... it's like a different boat to me.... furled jib... or jib out and jammin....
i only furl the jib when it's REALLY REALLY blowing... OR... when it's just REALLY ( 1 really ) and I'm going downwind...'cause of the small fore hulls wanting to dig in and send me end-over...

So... you've got a turbo setup... just no jib? ( meaning the dolphin striker wire, trap lines... bridles, furler, etc.. just no jib? )
