As designed by Williams F. Crosby in 1931
For all boats built after January 1, 2015

GENERAL RESTRICTIONS
1. The purpose of the restrictions under which Snipe hulls and sails are approved is to ensure that, to as great degree as
possible, all hulls and sails have identical racing capability. It is impossible to list every single variation that might turnup in the future, and it is impossible to make any set of restrictions, which at some future date, someone cannot findwhat appears to be a legal means of obtaining some racing advantage. Any boat or sail having features which are notconsistent with this purpose will not be approved and cannot race even though there is no specific restriction preventing
the item in question. Improvements and changes will be made only when these changes do not obsolete older boats andsails from the standpoint of racing capability or when they can be accomplished by anyone at reasonable expense.
2. Boats must be measured by officially appointed or elected Fleet Measurers or by Class Measurers approved by SCIRA.
No certificate shall be acceptable unless recommended and signed by such a Measurer. (See also Certified Builder Rule on
page__.
3. Boats, to be eligible to race in this Class, must be built to conform in every way to these measurement rules. A boat that
does not meet all these requirements shall be ineligible to receive a Certificate of Measurement, but it retains its identifying
number. Such boats cannot take part in any open or closed regattas whatsoever. The measurer must notify the Executive
Director of any boats that cannot pass these requirements, giving the boat number, and the name and address of both thebuilder and owner.
4. Nothing is optional in these plans, specifications or restrictions unless definitely stated as such.

Hull

Snipe Class General Restrictions 2015 – Amended November 2014 effective January 2015

Cockpit
12. Maximum width: 1016 mm (40"). If the deck alongside the cockpit curves down on a radius, the maximum width shallbe checked at the intersection of the deck with a plane 51 mm (2") below the sheer. Cockpit corners may be square or
rounded to any desired radius.

Construction of Fiberglass Boats
13. Only professional boat builders certified by SCIRA can make fiberglass Snipe hulls (See Certified Builder Rule, page_) Effective January 1, 1965, the construction of fiberglass hulls has been allowed under the same tolerances as approved by
ISAF and now in effect for wood hulls. The loft lines do not show any sheer molding. Part or all of a sheer molding may bemolded with hull. Each builder's method of construction of fiberglass boats must be approved by the Rules Committee.
The thickness of the hull must be uniform except where reinforced locally such as at keel, the chine, the stem, the mast step,
and where the stay anchorages and rudder gudgeons are attached. Increased thickness due to incorporation of flotationmaterial in either the sides or bottom of the hull is not a violation of this requirement. If desired, the floorboards may
bonded directly to the bottom on the boat, omitting supports. A fiberglass and foam sandwich floor structure may be used.
Wood and plywood are acceptable local reinforcements.
13.1. All professionally built boats must be measured before leaving the factory by a measurer satisfactory to the builder
and the National Secretary. Boats not so measured are prohibited from competition at regattas above the local level until
measurement is complete. Complete measurement includes a Moment of Inertia test.
Materials: fiberglass cloth, woven roving or mat may be used, with either polyester or epoxy resins. Glass content must be
at least 30% by weight.
Deck: The deck may be plywood or it may be fiberglass. In general, a fiberglass deck will require some type of double
surface and core construction for adequate stiffness.
Flotation: 0.184 cu.m. (6 1/2" cubic feet) of Styrofoam, Urethane foam, or equivalent, having a density of 40 kg cu.m. (21/2 kg per cubic foot) maximum must be built into the hull. Balsa wood or foam enclosed in resin-impregnated fiberglass
cloth is considered equivalent. Supposedly airtight compartments are not considered adequate.

Construction of Plywood Hulls
14. Bottom and Sides: The weight of the plywood used must be at least 5.65 kg per square meter (18 1/2 ounces per squarefoot). If 10mm (3/8") material is used throughout, fiberglass or other covering material may be used to bring the hull up to aminimum weight.
Flotation: 0.085 cu.m. (3 cubic feet) of foam must be installed in the hull.

Flotation
15. All boats shall comply with the following flotation requirement: when the boat has been capsized and has remained inany position long enough to take in as much water as possible in high wave conditions, it shall, upon being righted, float sothat the lowest point around the cockpit edge where water might enter the boat is at least 152mm (6") above the water when
the boat is supporting 136 kgs (300 lbs). This may be accomplished by means of tank, flotation bags, selfbailing cockpits,
increased low density floatation material, or other suitable means. Holes with maximum 645.2 sq.cm. (100 square inches)
may be made in the transom to facilitate drainage. Where transom drains are used to comply with this rule they should havea minimum of 290.3 sq.cm. (45 square inches) total.
For boats built before Jan. 1, 2001 meeting the requirements of this rule, the centerboard trunk may have aminimum height of 310 mm above the outside of the keel if the boat, after capsizing and being righted, floats highenough so that water will flow out of the trunk; otherwise, the trunk shall be 51mm (2") above the water level in theboat after capsizing and being righted.

Moment of Inertia Test
16. All bare hulls, as defined in paragraph 37 section 2 (bare hull), must be subject to the moment of inertia test (for a fulldescription of method, see Supplement to Measurement Data Sheet for Moment of Inertia Test). The moment of inertia of
the hull is calculated from the following formula:

Where: I = Moment of Inertia
C = Spring constant, lb. per ft. (kg. per m.)
Snipe Class General Restrictions 2015 – Amended November 2014 effective January 2015

D = Distance to axis, ft. (m)T = Time of one complete oscillation, seconds
 = 3.1416
For our purpose, D = 104” -1” + 9/32” = 103.281” = 8.6067 ft (2.6233 m).
The spring constant will be furnished with springs from SCIRA. The spring attachment shall follow the dimensions showedin the Supplement for the Moment of Inertia test. The maximum weight of the attachment shall be 350 gr excluding thesprings only; if desired, ballast shall be added to the aftermost part of the attachment to reach the maximum weight.
We can now simplify the formula to:
English:Metric:I

2.6233m 2 CT 2
 .1743CT 2
4  3.1416 2

The minimum moment of inertia of the hull as determined from above formula shall be:
Metric: 27.6 (metric slug meters squared)
English: 200 (slug foot squared)
If the hull moment of inertia dos not meet the minimum, weight shall be moved to or added to the ends to bring it up to theminimum.

Centerboard
17. Board: Verify dimensions with drawing, no other shape permitted. Maximum radius of bottom corners 13mm (1/2")*.
Centerboard shall be made of any hard aluminum alloy. 6061T6 or its equivalent is recommended.
The thickness of centerboard shall be 10mm (3/8"). There shall be no inserts or other means of changing the distribution of
the weight. Boards must be uniform thickness except within 25mm (1") of edges, which may be tapered off.
The centerboard widths have an allowance of +/-3mm.(1/8“) Centerboards may be cut out (minimum 940mm) for lightness(see drawing, page _).
The handle of the centerboard shall be installed in such a manner that the aft edge of the centerboard is perpendicular to thebase line when the centerboard is completely down, and the centerboard shall not extend more then 851mm (33 1/2") below
the keel. The 851mm (33 1/2") point shall be marked at aft edge on starboard side by a center punch.
17.1 Effective Jan. 1, 2001, centerboards complying with the measurement restrictions set out in Rule 17.1 (above)
made of sheet molding compound (SMC) manufactured by Inapal Plasticos of Portugal may be used in any Snipe
regatta up to, but not including, national championships and major international championships. In addition
however, the national secretary of any SCIRA country may approve the use of the SMC centerboard in the national
championship of that country. Boats sailing with the SMC centerboard must add weight where it may be easily seen
if necessary to comply with minimum weight restrictions of the Class. Such weight shall be permanently attachedwith peened over bolts, glass cloth, or permanent mastic. Only one centerboard may be measured and used at a
regatta.
17.21 Trunk: Slot in centerboard trunk maximum 546mm (21 1/2") long and no more than 13mm (1/2") in width if infiberglass or 14mm (9/16") if in wood or plywood. The aft edge of the centerboard trunk shall be perpendicular to base line.
Forward edge of centerboard trunk shall either be perpendicular or slope forward 6mm (1/4") maximum at the top of trunk.
If seals are used on the centerboard trunk, they shall be used at the top of the trunk only. Any type of seals may be used.
For all boats built after Jan. 1, 2001: the aft end of the centerboard trunk must be 310mm, -0 + 3mm (12 1/4", -0" + 1/8")
from the outside of the hull to the top of the trunk. The top of centerboard trunk shall be parallel to baseline*.

Exception to Applicability of Prior Rules (#17)
The new centerboard shape and thickness must be used after January 1, 1976 on all boats in the World Championships,
Western Hemisphere Championships and European Championships. Those existing boats which cannot use a 10mm (3/8")
thick board because of trunk slot width shall use a 8mm (5/16") thick board of the new shape. The length of the trunk slot
shall be 546mm (21 1/2") maximum.
18. The centerboard must be restricted while racing in such a manner that no point of the bottom edge extends less than 305
mm (12”) below the keel. To permit checking the position of the centerboard while racing a band 25 mm (1”) wide and 150
Snipe Class General Restrictions 2015 – Amended November 2014 effective January 2015

mm long shall be painted on each side of the board. The top of the band being even with the surface of the deck at thecenterline of the boat while the board is raised on the maximum height. A safety line must be used on centerboard while
racing. The safety line shall be long enough to permit, when completely tight, to raise the board up to 50 mm over the upper
part of the board band to the deck. No retaining system is allowed that will permit the centerboard to be held up so that thecenterboard band is above the deck, as, for example, adjustable retaining lines and shock cords. Only retaining systems
consisting of a hook and cuts on the centerboard or consisting of a tablet/flapper are allowed. At National and International
championships the compliance with this rule of the retaining system must be measured on each boat and can be checked on
the water at any time.

Rudder
19. The rudder shall be made of wood, wood & fiberglass, fiberglass or fiberglass & foam. Metal rudder blades areprohibited. Only one rudder may be used during a regatta unless irreparable damage has occurred.

22. The minimum weight of the rudder including pintles shall be 2.72 kgs (6 pounds). Weight of no more than 450g. (1 lb.)
may be permanently attached to a rudder to reach the minimum weight.
23. Where pivoting rudders are desirable because of purely local conditions, they may be used for local races only. They
may not be used in any regattas or championships.
24. The tiller shall be strong and attached firmly to the rudder head in such a manner it cannot be slide fore and aft and does
not extend far enough aft to artificially lengthen the boat. Tiller must be directly connected and completely above the aftdeck.
25. The rudder must at all times be mounted parallel to the transom. It must be attached to the transom and as close to thetransom as conveniently possible with 38 mm (1 1/2") maximum clearance. Vertical adjustments or changes in angle are notpermitted. There shall be a suitable means of preventing the rudder from falling off with the boat inverted.
26. The gudgeons & pintles shall be 8mm (5/16") diameter.*
26.1. The lower gudgeon shall be mounted on the transom 155mm (6 1/8") +/-3mm (1/8") above the intersection of thetransom and the keel. The upper gudgeon shall be 410mm (16 1/8") +/- 3mm ( 1/8") above the intersection of the transom
and keel.
2726.2. The cross section width shall be a minimum of 140mm of material measured at 90 degrees from the leading edge
vertical axis 305mm above the knuckle point. There is no tolerance at the knuckle. For rudders built after 1.1.2015

35. A band 25mm (1") with the forward side located at 2559mm (8'4 3/4") aft of the aft side of the mast (the aft side of themast includes the sail slot and material enclosing the boltrope), will limit the length of mainsail foot. A screw or otherstopper shall limit the mainsail foot so that the aftermost edge of the sail at the clew shall not be stretched beyond theforemost edge of the band.
Snipe Class General Restrictions 2015 – Amended November 2014 effective January 2015

36. Boom shall be essentially straight, and shall not be tapered nor have lightening holes. The boom ends may be cutoff
with a maximum angle of 45º. The height of the boom at either end may be reduced for access to blocks or boltrope.

38. Effective January 1, 1996, measurement certificates shall include a hull diagram showing ballast weight and locationand Moment of Inertia value.

Sails
39. In all races, skippers must use their own sails. Masters and juniors may use borrowed or chartered sails for theirrespective World Championships. The number on the main sails shall correspond to a measured hull on which dues for thecurrent year have been paid and registered in the skipper's name. If he owns more than one boat, he may use numbers
corresponding to either boat (See paragraph 19, Constitution, on page _).
Numbers: Placing of racing numbers, letter and emblems shall comply with ISAF rules and additional detail requirementsof these Class rules. Racing numbers shall be located at different heights on the two sides of the sail, the median distancedown from the top of the sail being between on third and one half the distance from the top of the sail to the boom.

40. Materials: Any type of woven polyester fabric or polyester film/scrim three-ply laminate material may be used as longas it has a minimum weight of 111.4 grams per true square meter (2.6 oz. per sailmaker yard). Jibs manufactured after
1.1.2013 must use any allowed material of minimum 160gr/sqm. The weight of the material shall be indicated by thesailmaker by a stamp at the top of the sail. Beginning January 1st 2015 the use of jibs made of 160 gr/sqm shall bemandatory at national championship level and in all the regattas with a deed of gift published in the rulebook. A nationalsecretary may allow the use of older jibs made of 130 gr/sqm minimum weight in his country national championship in2015 only. Laminate material approval is limited to commercially manufactured, readily available materials which are costcompetitive with woven materials and which have been specifically approved by the Rules Committee on a case-by-casebasis. One transparent window of non-woven material may be used in each sail, if desired, with a maximum area of 1858
sq.cm. (2 square feet) per window.
41. Construction: Leeches must be folded or capped with at least one additional layer of material of at least the same
Snipe Class General Restrictions 2015 – Amended November 2014 effective January 2015

weight as the body of the sail or its equivalent. Sails may be seamed or glued.
42. No extra battens or other means of artificially stiffening the leech of either sail shall be used.
43. All sails shall be measured according to the measurements effective from January 1st, 2011. Sails manufactured
before January 1st 2000 shall comply with the rules in force at the time of manufacturing. The dimensions as given are
for maximum measurements. Sails over dimensions on any side are not allowable. A new sail must not be approved which,in the Measurer’s opinion, will not be within the specified limits after "breaking in".
Sails are subject to re-measurement and cancellation of approval at anytime. They must be measured at the start of eachseason and so marked.
All measurements shall be taken disregarding roaches, straight-line., to centers of grommets and no allowance shall bemade for miss-located grommets resulting in the sail being smaller than maximum size permissible. If a grommet is
located farther from edge of the sail than is permissible, the sail must not be accepted. See supplemental drawing on
limiting sail dimensions. pages _.
All jib dimensions and main leeches shall be subjected to a direct pull of 3.6 kg (8 lbs) when being measured.
Mainsail shall be measured with battens in place.
Spinnakers are not permitted.
The Measurer shall mark the tack of each approved sail with the date and his initials before it may be used in any race.
44. Royalties: a SCIRA sail royalty label must be permanently attached on every mainsail and jib. No new sail can be
accepted nor measured by a member for racing purposes without a label; it is not a Snipe sail unless the royalty label
appears thereon. It is the obligation of the sailmaker to buy these labels from the SCIRA Office.
45. Mainsail: Mainsail luff and foot need not be measured. The limiting dimensions are checked on the mast andboom when the boat is racing. Maximum dimension of leech 5334mm (17’6”). Loose-footed mainsails areprohibited.
45.1. For sails built after Jan. 1, 2000: To measure quarter girth and batten position proceed as follows: to determine the
mid-point of the leech fold the sail until the center of the grommet in the headboard head point coincides with the centerof the grommet at the clew clew point. Remove any wrinkles in the leech and mark this point on the leech with pencil orpermanent mark. Then refold the sail so that the centers of the grommets in the headboard head point and clew the clew
point coincide with the midpoint. Remove any wrinkles in the leech and mark these two new points on the leech. Measurefrom each of these points to the nearest point on the luff including the boltrope. Use only enough tension on the sail toremove wrinkles.*The maximum dimensions across the sail are:upper quarter girth:
1067mm (3' 6") *mid-girth:
1755mm (5' 9 1/8")*
lower quarter girth:
2238mm (7' 4 1/8")*
45.1. For older sails built before January 1st 2000: Maximum dimension of leech 5334mm (17'6”) from center ofgrommet in the headboard and clew. The maximum dimension across the sail from the mid point of the luff to themid point of the leech is 1791mm (5' 10 1/2''). Determine the mid point of the luff by folding the sail until the centerof the grommet in the headboard coincides with the center of the grommet at the tack. Determine the mid point of
the leech using the headboard grommet and the grommet at the clew. The measurements are from the inside of theboltrope to the leech and shall be checked with only enough tension to remove wrinkles.
46. Bolt ropes may be cut back at the tack no more than 254mm (10"). The boltrope on the mainsail foot and luff may be
cut-out, at tack only.
47. A grommet may be installed in the mainsail to permit tightening the luff while racing. A line may be rigged through thisgrommet in any manner desired in order to tighten the luff.
48. Maximum length of mainsail battens: (Pockets not over 38mm (1 1/2") longer than batten)
Top batten
457mm (18")
Center batten 686mm (27")
Lower batten 610mm (24")
Batten position is measured to the center of the batten pocket.
49. The maximum dimension across the top of the mainsail shall be a maximum 176mm 185mm (measured perpendicular

to the luff) from inside of including the bolt rope. The top of the mainsail shall be perpendicular to the luff.
49.150. The mainsail leech between the headboard and the upper batten shall be straight or nearly straight like the otherleech sections (between battens and lower batten to clew).
50. Jib dimensions:
For sails built before January 1st, 2000, from centers of the grommets:Foot
1956mm (6'5") maximum
Head grommet to midpoint of foot3708mm (12'2") maximum
Luff
3734mm (12'3") maximum
Leech 3505mm (11'6") maximum
51. Jib. The use of jib hanks is optional. If used, there shall be a minimum of 5 and maximum 10 hanks, one at each end of
the luff and the others evenly spaced between them. If glove fasteners are used a maximum of 254mm (10") of the forestay
may be covered. Jib may be sheeted inside or outside shrouds.
No battens whatsoever allowed in the jib.
All jibs must be capable of being attached without disconnecting the forestay. The jib must have a wire or a fiber line
(excluding PBO and Carbon) attached to the luff while racing. The jib luff wire must be attached to deck and it cannot be
moved while racing.
51.1 No headboard or leech line permitted in the jib. Flutter patches on seams between sail panels are allowed within
200mm of the leech. The maximum number of additional cloth plies allowed is two. The patches must be of the samematerial as used in one of the adjacent panels of sail cloth joined at the seam. A single patch which is folded over once
constitutes two layers. Folding a patch multiple times to create more than two additional overlapping layers is not
permitted.
51.2 The roach on leech and foot shall form a uniform curve from grommet to grommet between limiting points without
any voids scallop or hollows in the uniform radius. The mid girth measured across the sail shall be 1035mm 1025mm
maximum.
51.3 Head girth measurement. See supplemental drawing page _.

52.10 All metric measurements are taken to the nearest millimeter*.Questions must be resolved by using the customarysystem which is also shown, and which was used in designing the boat.
52.11The maximum overall length of the whisker pole is 2642mm (104") and it may not extend in front of the bow of theboat or aft of the boom when not deployed. Pole launcher and retractor system using shock cord are allowed. The mastfitting from which a retractable whisker pole is launched shall not project further than the forward face of the mast.
52.12Carbon, aramid fibers or micro-grooved film shall not be used in hull construction or major equipment. Exotic
materials may be used in running rigging fittings only if commercially manufactured and readily available on the open
market at prices competitive with similar fittings and equipment of non-exotic material.
52.13. Electronic devices that allow bearing and timer only are allowed.

Miscellaneous
52.14 Boats must carry wearable life preservers for all occupants at all times, and race committees may require wearing

Sentences marked * shall apply to boats, masts, booms and sails built after January 1, 2000.

Certified Builders
A close relationship should exist between builders and sailors for such relationships are among the many strengths of theInternational Snipe Class. The intent of this Builder Certification Rule is to provide a workable structure for thisrelationship and to provide a measure of protection for both builders and sailors alike.
To be certified as a Class Builder by the Snipe Class International Racing Association (SCIRA), a builder must agree to andabide by the following requirements:
1
Certification by SCIRA will be required before hull numbers are sold to any new or established builders.
2
To renew the Certification, at least one boat of any ten manufactured or one boat per year, whichever is shorter
shall be completely measured by an International Snipe Class measurer or an ISAF measurer.
3
An International Snipe Class Measurer, or the measurer’s designee, shall measure all new boat molds of newbuilders and the first five (5) boats manufactured by new builders, at the builder's expense. There will be an International
Snipe Class Measurers selected for Japan (1), for Europe (1), for South America (1), and for North America (1).
4
Any change made on the moulds of an established builder shall be communicated to the SCIRA office and thechief measurer .
5Every certified Class Builder shall select a Builder's Measurer, who shall be satisfactory to the builder’s national
Snipe Class Measurer.
6
The Builder's Measurer shall measure all the fittings, appendages, rig and spars of a new boat manufactured by thebuilder, to include weighing and the Moment of Inertia (MOI) test, at the purchasers expense. A Measurement Data Sheet(MDS) shall be completed in full by the Builder's Measurer for every new boat manufactured by the builder. The MDS shallthen be mailed to the Executive Director of SCIRA and National Secretary, and a Measurement Certificate shall be given to
the first purchaser. In the event that an MDS cannot be completed, for whatever reason, the MDS shall be mailed to the
Executive Director of SCIRA will an explanation of the reasons why the MDS could not be completed. A copy of the MDS
and the explanation shall also be mailed to the builder's national International Snipe Class Measurer. The purchaser shall
only be charged a prorated measurement fee corresponding to the percentage of the MDS that was completed.
7
Every certified Class Builder shall correct manufacturing defects in the boats the builder manufactured, wheneverthey are found.
8
Any certified Class Builder who repeatedly fails to comply with any of the foregoing requirements, or who
breaches the requirements in a material way, shall forfeit certification as a Class Builder, after due notice, and may not be
re-certified for a period of at least one (1) year9
All builders who are actively manufacturing boats as of December 31, 1999 shall be certified by SCIRA as
established Class Builders under the foregoing requirements.
