your budget is 3k? or you will have double that amount? (selling 2 boats).
where are you located and where do wish to go?
you can't be in a hurry if you want to sail... in sailing its more about getting there.
in a powerboat its more about what you do once you get there.
its also more work to sail, but you typically get more for your money. especially when you start looking at boats over 30 feet.
you can get a lot of sailboat for 30k.
then there are the powersailers, like the new macgregor M (can plane in good conditions avg ~14knts )
