Katamaran
They seem to meet some of what you're after.
13ft long 6ft wide and 93 lbs for under $3,000

I'm assuming you're trying to find a way to get kids down to the water and sailing a cat without a big hassle, a trailer and with no mast up storage.

I don't think the original idea was to start an F12 class.
