PHRF OF EASTERN CONNECTICUT
The Performance Handicap Racing Fleet of the Eastern Connecticut Sailing Association
2008 REGULATIONS
I. General Regulations
Handicap ratings are based on boat speed potential, determined from the demonstrated speed of "standard" boats, that are expertly
sailed, well equipped, and conditioned. A standard boat must be equipped to the degree intended by the manufacturer, including
those appointments and equipment supplied or intended by the manufacturer, such as joiner work, cushions, galley equipment, etc. It
is the responsibility of the applicant to provide details of all changes that could possibly affect boat speed. To qualify for a handicap, a
boat must be singlehulled and selfrighting. Also, the use of a trapeze, hiking straps, hiking boards, or any other hiking aid is not
permitted. A boat shall not have more than one current Eastern Connecticut PHRF Certificate at any time. Rating changes based on a
change in headsail size will be limited to one per season.

III. Handicap Adjustments
NonSpinnaker Rating
NonSpinnaker ratings are based on the ratio of mainsail size (including mizzen sails, if applicable), to foretriangle size as follows:
Ratio = (P x E + [PY x EY] + [.6LLY x LPY]) / (ISP x J).
Rating Rating RatingRatio Adj. Ratio Adj. Ratio Adj.

Mainsails
Unless standard for a class, unpenalized mainsail girth shall be limited as follows:
MGT (7/8 leech) shall not exceed .22E
MGU (3/4 leech) shall not exceed .38E
MGM (1/2 leech) shall not exceed .65E
Mainsail girths exceeding these dimensions must be declared, and will be penalized on an individual basis.
Excess mainsail foot (E) shall be penalized at the rate of 1 second/mile for each additional 5% or fraction thereof.l

Asymmetric Spinnakers
(To classify as a spinnaker, the AMG shall not be less than 75% of ASF.)
PoleFlown or DeckTacked An AMG of up to 180% J, and an average of the leech and luff lengths ((SLE+SLU)/2) not exceeding
SLIM, shall be permitted without penalty. Oversized sails will be penalized using the same methodology as for symmetric spinnakers
(see below), except the average of the leech and luff lengths will be substituted for SL.
Oversized poles will be penalized using the same methodology as for symmetric spinnakers.
Decktacked asymmetric spinnakers may be flown from a pennant not exceeding 2 feet in length, and will receive credit as follows:
TPS Rating Adjustment
Up to 100%J +9
Greater than 100%J to 112%J +6
Greater than 112%J to 124%J +3
Greater than 124%J No credit
SpritFlown Base boat rating will be based on the largest standard asymmetric spinnaker, as specified by the boat manufacturer.
Additional sail area will be penalized at the rate of 1 second per mile for each 5% increase, or fraction thereof, in sail area.
Symmetric Spinnakers
Spinnaker rating adjustment is based on the largest spinnaker measured by the G/J ratio and the SL/SLIM ratio. A luff length equal to
SLIM is standard. The maximum girth without penalty is equal to 1.8 x J. If spinnaker luff length is greater than standard, excess length
is converted to excess girth. Convert the excess luff to excess girth using the following formula: G/J Rated = (G/J Actual) (SL/SLIM).

Modified Appendages All modified rudders shall initially be given 3 sec. penalty until reviewed by the council. Modified keels must
be reported to the handicapper.
