If you are going to compare PHRF, better ad in a 1D35 at about 30 or there abouts, melges 32 in the very low double digits, they go to weather quite well.
PHRF will not address the how close you can sail to the wind for the most part. For that, you need to look at deck gear, ie how close to centerline is the jib tracks, 8-9 degrees, you will tack quite close, start talking 12-15* not as close, altho it might be abit faster, as 12* off is faster than 8*.
