The Bayfield 25 is a cute little character cruiser, a comfy boat if you don't need much room, but will be a bit sluggish performance wise. The trailer is a definite bonus, but in today's market I'm not sure that it wouldn't go for a bit less.... but in pristine condition (trailer included) it's a starting point for sure.
