These boats have always appealed to the traditionalists with their "salty" lines, clipper bow and pinrail teak trim.
The 29 is a decent 2 person cruiser, as long as you're not in a hurry. Performance to weather is not going to be great with that underbody, but you have the advantage of shallow draft at other times.
Rating level with older, moderate performance 25 footers gives you an idea of their speed (did anyone really pay for a PHRF rating for one of these??) The rating is likely irrelevant otherwise, not many are raced.
The lack of a permanent double berth could be an issue for couples as well (who likes to put up and take down the berth every day?)
Designed by Ted Gozzard, who continues to produce boats of that "look" in a more high end market nowadays.
