Welcome to the forum. Sailing is a great family sport.
There are several threads addressing the pluses and minuses of buying
a boat out of charter. As long as you recognize that it has probably been used very hard and go into with eyes open, why not.
One thing I don't favor is that you are buying
the "charter version" which maximizes bed
and heads. That could be a plus for a family.
Search the threads and read up on the opinions of buying boats out of charter. There are lots of good comments pro and con.
Again, welcome aboard.
