We are a family
of four (kids are 4 and 10mths but we dont plan on setting sail for another two years) have been looking at this area too. If you haven't already, go to yachtworld.com and you can set your limits. We have been looking at ex-charter cats like Leopards and Voyage. I personally prefer Voyage 440 and my husband prefers Leopards. There are lots of posts in here comparing the two but it seems to always come down to personal preference and the individual boat. Charter
companies do 'off loads' once a year, i believe, and flood the market so prices can be dropped. Tuimarine.com have the ex-charter Moorings fleet but they are mostly always listed on yachtworld.com anyway.
Good luck. It's a mine field out there
