[quote=dssaak]The conversions from DPN to PHRF works for like boats because relative speed stays somewhat consistent as the wind increases. At least within the changes to the applicable ratings. That isn't necessarily true if you are racing multi v mono as the relative speed variation increases for nearly every boat you will race against. That is why we use, successfully I may add, B Factor adjustments according to wind conditions.[/quote]
