The US 29s are based on Doug Peterson designs, so apart from the typical '70s IOR tendencies to death roll under spinnaker these boats move well. Large genoas and kites, small skinny main leads to difficulty handling large headsails, esp the kite in a breeze.
However these boats were built by Bayliner, (Buccanneer) and the execution was not very good. As a sheltered water coastal cruiser it may be fine as long as it's in good condition.... but even at a bargain it needs a real good going over. Not getting a survey is a mistake, IMO.
