Shakey, depends on locale, jib, etc,
I think PHRF's differ from region to region. As a ball park number, though, there's a 340 on Haverstraw Bay, Hudson River, with a 132% jib with a 174 PHRF. Also, the boat was reduced by 3 points b/c of 900 lb. weight limit. I'm told a folding prop will cost you 6 points, but its well worth it.
