i too have looked at the bayfield 25....
personally i have no "hands on" experience but what i do know is they changed interior design around 77/78 i think. went from more wood, porta potti, less headroom to marine head, more grp looking interior and i think maybe an inch or so more headroom. i've seen one go on ebay for $7k and see listings in the $10k- $12k range. sure a pretty boat with a good "pocket cruiser" reputation. i read that the,(8hp is it), yanmar is a bit anemic for the boats weight. think there are some interior design options too....dinette, aft galley etc but this may have just varied between yr models. i'll include a link to a bayfield 29. (my "25" link no longer works but this site has some other bayfield links.)the link didn't work so heres the long ver: http://www.tcc.on.ca/~dbieman/b29/
