Re: C&C 30 interior question
I would say there's not much in it either way... techincally you've got 5 sleeping spaces, with the 30's dinette 4 of them are 'doubles'.. with the quarterberths and centerline tables the V berth is the only 'double'.
The cockpits are very similar, and that's an area where you're likely to 'feel the squeeze' for space as your kids get older (and bigger).. These boats do not have large cockpits.
Personally I think the 29 MKII is the prettiest of the lot, but it's also probably the smallest overall. Surprisingly there's not necessarily that much price diff between the three of them, with the 'cherry' MKIIs drawing the higher prices as a rule.
Ideally, of course, you get yourself on examples of all three.. you'll know which one suits you best...
