best family day sailor is a Flying Scot, pretty fast, very roomy,
reasonable to buy, and quite stable. and you can trailer it with a
Toyota Corolla or similar. If you wish to race sometime, there are
fleets nationwide. Check it out on the net...

I owned a 470 for a while, fun boat, but not what you are looking for.
I sold mine for $950, and the hull was practically brand new, rarely
sailed and never raced.

buena suerte!
