Chuck is absolutely correct, different PHRF have different rating
adjustments. Do pull up the rating adjustments for the PHRF area you
are in when making significant investments on a boat.
On Narragansett Bay we review our rules/rating adjustment yearly and
changes are published and voted on by the members. PHRF-NB use tables
for headsails, mains and spinnakers based on the sail area. We are
trying to keep boats racing and believe that giving some relief to those
who are moving from cruising to racing or can no longer afford a full
sail inventor; ie, headsail 1>4, code 0, spinnaker .50 and .75 oz, etc.
As an example the headsail table adjust the rating by 1sec/nm for every
3% of the sails LP% change with 155% being 0 sec adjustment, 170% -5sec,
145% +3 sec, 135% +6 sec and 125% +9 sec. (samples from table).
