Default Ocean yacht 45 vs 48

Looking at a mid/late 90s ocean yacht 45 and 48 convertibles. I found on another thread info on the 45 with 671DD doing about 20.6kts at 1800 rpm and getting 25gph. these numbers were pulled from a chart published which im sure is a bit optimistic. The late 90s 48 i cant find a chart for but I am told with 691DD it will do closer to 20kts at 40gph+. it seems like I am off base somewhere as a 45 to 48 cant be that much difference right? the 45 in the chart has a weight of 37k. I am not interested in running "fast" I regularly cruise now at 24-25mph and love it.

My late 80s 48 would cruise at 20kts at about 40 gph with the 671s. If the bottom is a little dirty you are looking at 18-19 at cruise. I have no experience on the 45.

The 48 Is a lot more boat, 3 staterooms etc, same systems shouldn’t be that much more money to run and maintain
