Six Maps is good however, you cannot save anything but you can measure paddock sizes.

I think Agworld has these features and it's free, so that could be worthwhile looking into.
Then there is Agriwebb - that is a paid subsciption, however I think they offer a 14 day trial?
There is probably plenty more out there but they are the ones I know of and have used.
There is a long list of mapping/ farm management software avialable. If you want basic mapping without having to pay, try PA source. Maia grazing software also has a good mapping facility which i believe is available in the free version.
