I'm in the same boat (so to speak)
but my job is still here, so I'm delaying, and planning. My budget so far is $20k for a boat, and my time frame is 10 years to buy, and get to know the boat, ease out of working, plan my transition from landlubber to sailor. There seems to be a TON of experience and great people to share it on this site, so that's where I'm starting. What an advantage, having a community of seasoned sailors in a forum like this. Along with reading books and looking at classifieds for boats, there is a wealth of information available.
