Anything is possible, but that doesn't make it practical. 6 months may seem like an eternity to you (although, as I age, it starts to feel like minutes), but unless you're talking about spending all 180+ days learning to sail, you're biting off a pretty big chunk. 3,000 (learned something, btw) is a long, long, long way. Did I mention that's a long way?
Again, anything is possible, but it may be a little more involved than you think. Do like others have suggested and spend some serious time on the water first, then decide for yourself. But....when you're "gaining that experience", make sure it's far enough away from shore that you can't see land. That feeling is a little spooky the very first time. Good luck and keep us posted.
