in regular crew? If so ages?
$100k budget to buy and outfit the boat? (living and cruising costs extra.)
Where are do you want to cruise
out of? Which coast do you want to set off from and more specifically where on that coast?
Where to you want to go?
Are you looking to cruise
extensively or liveaboard
and occasionally take several weeks or months off to nip around the Caribbean
I don't really have much to offer you advice-wise since I am exclusively a sailor, but I have found that asking questions to clarify your needs can be very helpful to the person asking and to the people with advice.
The one piece of advice I do have regardless of boat type, for long-term cruising, kids
need their own permanent berths preferably not in the bow of the boat where it will be very uncomfortable underway or in a bouncy anchorage. A berth that has to be converted nightly from the seating for dining or whatever just isn't good enough, they need their own permanent space no matter how limited.
Do you realize that an older larger sailboat will have much better fuel
economy for about the same up front price and same interior
living volume? Count on the vessels you listed getting about 1-3 mpg at 7-9kt speed and a larger sailboat getting 6-10mg motoring at 6-7kt. If you actually sail the sailboat then gas milage can run into the 100's perhaps 1000 mpg. If sailing is not really your thing or circumstances dictate a motor
vessel then ignore this paragraph.
