I've found a "late 70's era fiberglass" tornado for sale that is well within my price range and I've got a few ?'s for the Tornado sailors amongst us.

1) I'm guessing that this thing has the "old rig." What does this imply? Is the main sail shape different? If I were to want to upgrade to the "new" rig, what would it cost me? How about the helm systems?

2) The boat comes with a trailer, albeit non-tilt. Is it possible to trailer it assembled down the road like this?

3) Under mainsail alone, would it be possible to singlehand this boat?

4) Is there anywhere online I could find a spec sheet for line lengths for the tornado? (like the NAHCA site for hobies?)

I realize that I'd have to spend a lot to get this boat up to date, but I've done it with one boat already, and the money leftover from selling mine could more than pay for the parts to get this other one on the water.
