I've been looking at the 48's from the late '80's to mid 90's in great part because of the 3 stateroom layout (among other things), but I've seen the occasional 46' with 3 as well. However, I haven't been able to ascertain any major differences between the two just by broker descriptions and Internet searches. I assume the 46'needed improvements based on the simple fact that it was replaced by the 48'. Can anyone enlighten me on their differences? Thanks!
