·      DATE MFD: Date of manufacture or model year, if known.

·      OTHER RATINGS: Indicate a PHRF rating received from another area, e.g. NE-PHRF: 72; IMS GP: 622. For new or custom designs, this information is especially helpful to the committee.





MUST BE FILLED IN!  Dimensions can be measured or can be obtained from the manufacturer's brochure/specifications, or IMS certificate. If in doubt, measure! If standard information (such as I, J, P, SPL, or displacement) is not provided to the committee, the committee may assume the standard dimensions for the boat being rated, if possible. It is the boat owner's responsibility to verify this information. The committee assumes no responsibility if the rating is successfully protested on the basis that the standard dimensions used by the committee do not match your boat.


·         I:         Height of foretriangle. Measured from deck sheer line abeam the mast to the point of masthead/forestay intersection.

·         J:         Distance from foreside of mast to the point of intersection of the forestay with the deck.

·         JC:      The total length rom the front of the mast to the tack that spinnakers, etc.are attached to

·         P:        Distance from the upper edge of boom (lower black mast band) to the lower edge of upper black band.

·         E:        Distance from aft side of mast to inboard edge of black band on boom.

Record the bowsprit length (if one is to be used) in DIST FWD of HEADSTAY, and total distance forward plus J in JC in the spinnaker table. The spinnaker/whisker pole length is measured from centerline of mast to the extreme outboard end of the fitting with the spinnaker/whisker pole in its mast fitting and set in a horizontal position. If no spinnaker/whisker pole is used (e.g. asym sprit boats) then enter "0" in the SPL field.  The bowsprit length is measured from forward side centerline of mast to the extreme outboard end of the fitting with the bowsprit fully extended.

·        ISP:    Height of the spinnaker halyard measured from deck sheer line abeam the mast to the point of the spinnaker halyard exit from the mast.

This section must be filled out if asymmetric spinnakers are use. 

·         ARTICULATING POLE AT MAST: Check this if the asymmetric is tacked to an articulating pole that is attached to the mast (e.g. spinnaker pole).

·         FIXED POLE TO MAST AND BOW: Check this if the asymmetric is taked to a non articulating pole that is attached to both the mast and the bow.

·         BOW: Check this if the asymmetric is taked on the centerline at the intersection of the headstay, i.e., no spinnaker pole, bowsprit, or anchor roller.

·      FIXED POINT: forward of head stay attachment on centerline.

·      RETRACTABLE bow sprit.

·      ARTICULATING bow sprit.

·         DISTANCE FWD OF HEADSTAY: When asymmetric is tacked forward of the headstay, either on the bow, anchor roller, sprit or pole, fill in the distance in feet forward of the headstay.

HEADSAILS TO BE USED: Fill in boxes with  LP % size (e.g. 150%) for each headsail carried. The luff of headsails must be attached to the headstay. The midgirth of headsails must be: for sails with LP > or = 118% midgirth must be < 50% of the foot and for sails with LP < 118% midgirth must be less than 55% of the foot. Headsails with midgirths greater than these limits are NOT valid for racing.

SPINNAKERS TO BE USED: Enter the JC, SMG, Foot, Luff and Leach dimensions in the table for Spin1, Spin2, and Spin3 of the three largest spinnakers amongst the inventory of symmetrical and asymmetrical spinnakers.  All dimensions to be given in FEET. JC measurement is for Asymmetric spinnakers measured from the forward side of the mast to the point where the Asymmetric is tack to (anchor roller, fixed bowsprit, retractable bowsprit, etc.). For measuring SMG see "Quick reference for measuring Asymmetrical Spinnaker Mid Girth" (SMG) under the "White Papers" tab.

CODE0: A Code 0 is any free flying headsail that is a cross between a spinnaker and a genoa.  If a Code0 sail is being used, enter the JC, SMG, Foot, Luff and Leach dimensions of the Code0 in the table (SMG = mid girth length from midpoint of luff to midpoint of leech). All asymmetrical spinnakers must meet the criteria of “R11” below.

If you will use more than 4 genoas (95% or greater) or 3 spinnakers, you must supply information under Comments/Modifications In addition, use of any asymmetrical spinnakers, and oversize spinnakers, and the type of pole/sprit which will be used, and oversize mainsails must be reported under Modifications. Please read the Modifications Instructions carefullly!


HEADSAIL CREDITS: If you race with  one or more Roller Furling headsail(s) that are (MUST MEET ALL CRITERIA):

·            short hoist (i.e., its luff length is at least 2.5% of the I measurement shorter than the headstay length (Headstay length is measured from deck sheer line to mast))

·            attached to a bottom drum and top swivel and regularly used at the primary racing headsails, and is roller furled during racing (Note:any number of headsails 110% or smaller, roller furling or non-roller furling can be used as appropriate)

Check the “ROLLER FURLING HEADSAIL” box for a  3 sec/mile credit.


If you race with a roller furling headsail that meets all of the above ‘’ROLLER FURLING HEADSAIL CREDIT” criteria, and, in addition (MUST MEET ALL CRITERIA) :

·            is the only headsail greater that 110% LP used  for racing  (Note: any number of headsails 110% or smaller, roller furling or non-roller furling can be used as appropriate)

·            is regularly stored on the headstay when the boat is not racing or sailing

·            is regularly used as the primary genoa when the boat is daysailing and/or cruising

·            has a UV material leach cover attached to the sail (e.g. stitched or glued)

·            all head sails must be of a woven polyester material (no exotic sail materials such as pentax, mylar, kevlar, spectra, technora, etc.)

Check the “CRUISING HEADSAIL” for a credit of  6 sec/mile.



  • Except when changing headsails, participating yachts rated as a sloop, may not fly more than one headsail at a time.
  • Yachts that are permanently cutter rigged (with rig type declared as “Cutter” on the application Certificate), may fly a staysail. The inner forestay must be set-up at all times. As only one headsail at a time may be flown by a sloop, a staysail shall not be flown by a sloop.
  • Headsails may be held out by a single spinnaker pole or whisker pole, attached to the mast, whose length does not exceed the base of the fore triangle (J) unless so declared on the application/Certificate (SPL).
  • Symmetric and Asymmetric spinnakers shall NOT be used during non-spinnaker racing.








FORWARD - PHRF separates boats into "production boats/one design boats" and "custom boats". A base rating is assigned to a production boat and one design boats and adjustments to this base rating are uniquely estimated for each boat based on genoa size, mainsail modifications, spinnaker pole length, mast modifications, propulsion, and any modifications noted herein.  If you have a One Design boat, any deviations or changes from its one design configuration must be reported.

If you have a CUSTOM BOAT and you have made any changes to your custom boat from your previous year's application, you must describe them on your current application.

The following describes what items or modifications are considered to be REPORTABLE and must be noted herein on your application. All reportable items or modifications must be described in the comment section of this application, or on a separate attached page. Issues which are considered to be NON-REPORTABLE ITEMS OR MODIFICATIONS need not be reported. If in doubt about the need to report a change, your guidelines are "If in doubt, fill it out!"




R1)   Any changes in material, size, or shape (other than fairing to design specifications) of the hull, deck, rudder, or keel.

R2)   Any canard rudder; other lifting or steering device forward of the keel; or any rudder, steering or stabilizing device added to the boat.

R3)   Removal or relocation of any interior or exterior structural components; changes in construction technique/schedule, or changes in materials of bulkheads and/or interior cabinetry,  that results in the removal or relocation of weight.

R4)   Removal of standard tables, floorboards, headliners, lockers, locker doors, permanent berths, and head enclosures, i.e., you are not allowed to “strip the boat”.  Cushions, however, are allowed  to be removed for racing.

R5)   Any internal ballast or removal/addition of lead or similar density material. Any moveable ballast, (i.e.. water ballast): indicate weight, location, volume, and rate of transfer or discharge.

R6)   Dagger boards in addition to keel.


N1)   Fairing to bring the hull, keel or rudder into design specifications. Wet sanding and/or waxing are allowed.

N2)   Flexible flaps to fair the skeg into the rudder are allowed provided they do not extend deeper than the skeg.

N3)   Water, fuel, and holding tanks maybe emptied as provided by US SAILING. Cushions may be removed.




R6)   Rig modifications such as, but not limited to:

a.     increase/decrease of mast height, boom length or spinnaker pole length.

b.     spinnaker/whisker poles exceeding 101% of the J dimension.

c.     change in cross-section and/or material or weight of any spar.

d.     addition/elimination of spreaders, shrouds or stays including running backstays, babystays, checkstays, and jumperstruts.

e.     use of cobalt, titanium, boron, carbon fiber in rigs, lifelines or lifeline stanchions.

f.     use of fixed/adjustable bowsprit for flying spinnakers.

g.     carbon or PBO standing rigging.

R7)   Headstays, mast stays, and/or partners that are adjustable while sailing, whether accomplished mechanically or hydraulically.

R8)   Use of hiking straps, trapeze wires or similar devices that would allow the torsos of the crew or skipper to be extended

          beyond the beam of the boat.



N4)   Removal, addition and/or relocation of deck hardware.

N5)   Additions or deletions of hydraulics.

N6)   Running rigging of any size or material.

N7)   There are no restrictions on instruments electronic or mechanical, autopilots, and on-board computers except that outside information may be received only as permitted by US SAILING.




R9)   Any sails or sail construction that would incur a penalty or not be allowed under IMS, or if a one design boat, eg Melges 30,

          is not allowed by the class rules:

a.     Full battens in mainsail are allowed, but any oversize mainsail girths larger than the standard IMS girths or one design specifications must be reported.
Girth at 7/8 leach = .22 * E
Girth at 3/4 leach = .38 * E
Girth at 1/2 leach = .65 * E

b.     Oversize headsails, oversize spinnaker luffs (1.10 times the square root of I squared + JC squared), Symmetrical Spinnaker luffs (.95 times the square root of I squared + JC squared) or mid girth (1.8 x SPL  (JC)) must be reported.

R10) Use of more than 4 headsails (95% and larger LP), and/or use of more than 3 spinnakers must be reported.

R11) You must report the use of any Code 0 and asymmetrical spinnaker and their dimensions (JC, SMG, Foot, Luff, Leach). A spinnaker is asymmetrical if the leach and luff differ in length by more than 4 percent. Indicate if the asymmetrical spinnaker will be flown from spinnaker pole or fixed or adjustable bowsprit. The following standards apply: the luff must not exceed 1.10 times the square root of ISP squared plus JC squared (where JC is the length reported for the spinnaker pole or bowsprit to which the asymmetrical spinnaker will be attached); the maximum mid girth does not exceed 1.8 times JC; and the mid girth must be greater than 75% of the foot . Spinnakers that do not meet these standards shall NOT to be used during racing.
