If it stays upright will it sail off in to the distance when you fall off?
I'd say within reason, yes it would, however the sail will swing around off the wind. Heave to if you like.
I'm guessing that for beginners you wouldn't be out in too strong a wind anyway, so how far could it go?
Yes I imagine also that it would tip over, but again its only for learners so you would have a very small sail, so wouldn't take much effort to keep it upright.
