Our First Boat at Age 50

[waterworldly]

OK, here goes, I am throwing us to the lions! We have done lots of homework (books, magazines, forums such as this) and after careful consideration, have made the decision to retire to a sailboat (we are mid forties and early 50's in good health). We have never owned a sailboat, but have sailed with friends on boats 42-100 feet in the waters around Miami. SO, the decision was made and over the past several years we have sold off all our collections (lots and lots) via Ebay, sold the house a couple of years ago, and now are in the process of selling our business. We are in a rental apartment with no strings, owned by a good friend who allows us to make our own lease. Once the business is sold, we are planning on purchasing outright an Amel Maramu based on all of our research. It will be a few years old (5 or so, but not older), but will be paid for up front, no note.
SO NOW WHAT? We are planning on having it delivered to us down hear and starting our sailing lessons from here while having a dock space, as we are very new to this and want instruction on our own boat. We are thinking the instruction and practice will take about 1 year in the Florida waters and Bahamas before we are skilled enough to take off.
NOW, based on this, in your humble opinions, ARE WE CRAZY, or does this sound like a sound plan?
Thanks in advance for your input.
