I bought a Getaway from Miami Catamarans, and I'll never buy one anywhere else! They keep their boats in excellent condition and you can't beat their price. They replace their fleet throughout the year, so I think you normally have a couple of their "older" boats to choose from which is really nice. I put "older" in quotation marks because they are 1 year old at most.
And not only do you get a great boat at a great price, you'll be working with some of the best people around! I'm not going to bore you with all the details, but I will say that they didn't just go the extra mile to accommodate me, they went an extra 100 miles (nautical miles of course

).
Message me if you have any questions. If you're in the market for a used Getaway, you should check with Miami Catamarans to see if they have anything available. You won't be disappointed!
P.S. Or if your just in Miami and want to go do some hobie sailing, all of the above applies to taking one of their boats out too. They're in a great location. Both days I was there were windy and sailing with the city of Miami in the background is really a fun experience. I'm not sure if these links will work, but they're to pics of me and my daughter out on one of their boats.
