Sea Diamond #1558, a 2001 MkII is getting official PHFR racing handicap (in addition to my skillset). I have all the other ratings, but need to know the LP of a standard 140 headsail. PHFR says the ratio is 'perpendicular distance from the luff to the clew' of the headsail. Anyone? My next race is March 5 - and teh club is insisting I have PHFR rating. thanks . Doug Williams
