Check out this link Hunter 28.5
Lots of info on the 28.5. The 28.5 was one of the better hull shapes produced by Hunter. The 2GMF20 Yanmar engines in these boats is bullet proof and has reasonably priced replacement parts.
Negatives but not show stoppers are the iron keel and some of yhe build quality. Very nice boat for coastal cruising, club racing. I have raced against 28.5s 28.5s for 15 years and they move well in light air.
There used to be an Allmand 31 where I docked. Large boat for a 31. Owner had a lot maintenance issues. He complained that the boat did't sail all that well but it was nice at the dock. The universal diesel kept giving him fits.
In the same price range you might look at the C&C 29-2, A couple of steps above in quality from either of these boats. Priced in the same range. One of the members of this board just put his up for sale last week in the Chesapeake. Nice boat. Sailboat 1984 C&C 29 Mark II
