ARTICLE IV- SPECIFICATIONS
The following general revision is effective January 1, 1985. It supersedes ARTICLE IV - SPECIFICATIONS as last revised in 1977 and published in the booklet entitled "International Blue Jay Class Association Constitution, By-Laws, Specifications, Rev. 1968" and contains all subsequent rulings now in force.
1. GENERAL. The Blue Jay is a strictly one-design yacht; nothing is optional in its design or construction, except as stated in these specifications. Tolerances are specified solely in order to accommodate the usual random variations in construction. They shall not be interpreted to permit deliberate variation from the normal lines or dimensions, nor are they sufficient to permit, evidence of such deliberate variation shall be grounds for refusing or revoking any measurement certificate. The intent of these specifications is to clarify and elaborate the official plans and all items not specifically covered by these specifications shall be as shown in the latest revision of the official plans. All dimension, intended or actual, not expressly prescribed in these specifications and the official plans shall be subject to a tolerance of plus or minus 1%. In case of conflict between these specifications and the official plans, these specifications shall govern. Interpreting any point not covered, or wording of obscure meaning, the intended meaning shall be considered, rather than any technical misconstruction that might be derived from the wording, keeping in mind at all times the basic intent of these specifications as set forth above. Any boat not conforming strictly throughout to the design, materials, construction, and dimensions set forth herein and on the plans will not be considered a Blue Jay, and will not be allowed to carry the Blue Jay Class emblem. In order to race in any regatta as a Blue Jay, a boat must have a valid measurement certificate on file with the Association.
All questions regarding the interpretation of these specifications and the official plans, and all construction questions not covered by these specifications of the official plans, shall be referred to the Chief Measurer. At his discretion, the Chief Measurer may refer such matters to the full Measurement Committee for decision, and the Committee may, at its discretion, refer them to the Executive Committee for decision. A yacht's only permanent means of identification is her officially assigned number, which shall be cut or burned into the starboard side of the centerboard trunk, or on the top face of the centerboard trunk cap, or on the inside face of the transom, in numbers at least one inch (1") high; such numbers shall not be altered, defaced, or obliterated unless the hull is so far rebuilt that a new number is officially assigned.
2. PLANS. Plans are transferable only through the office of the designer. They are issued with the understanding that one boat only will be built from each set unless application is made to the designer and specific permission is granted to build extra boats. Such permission will be granted only under conditions set forth herein under Paragraph 3.
3. ROYALTIES. A royalty or number tax or $20.00 (twenty dollars) must be paid by the builder to the designer on each Blue Jay built, and any boat built from plans for which said payment is not received may not be properly sold or entered in any race as a Blue Jay, nor display the Blue Jay emblem on its sails.
4. MEASUREMENTS AND WEIGHTS. Measurements and weights in the specifications and plans are in feet, inches, and pounds in accordance with standards of the U.S. Bureau of Weights and Measurements.

b. Foot length between the most forward point of the sail directly ahead of the tack, including bolt rope, if any, and the aftermost point of the sail, including bolt rope, if any.
c. Leech length between the lowest point of the sail directly under the clew, including bolt rope, if any, and the highest point of the headboard,
or sail material if headboard, including bolt rope, if any.
2. The draft and luff and leech roaches of mainsail to be controlled by measurement taken from midpoint of luff to midpoint of leech (midgirth) and from 1/4 and 3/4 along luff and leech respectively (1/4 girth and 3/4 girth), said measurements not to exceed:
1/4 girth: 2.78 feet or 2' 9 3/8"
Mid-girth: 4.87 feet or 4' 10 1/2"
3/4 girth: 6.66 feet or 6' 8"
Cross measurement of the mainsail shall include the bolt rope. The measurements shall be obtained in the following manner:
a. The luff midpoint shall be determined by folding the sail upon itself, with the topmost edge of the headboard, lowermost edge of the sail material at the tack, including bolt rope, if any.
b. The leech midpoint shall be determined in similar fashion, with the headboard folded down to the clew.
c. The 1/4 girth and 3/4 girth measurements shall be similarly obtained, by folding the sail upon itself from midpoint to respective corners, as defined above.
3. All sail measurements shall be made with the sail on a flat surface, with or without battens.
4. Headboard of mainsail---the width of the mainsail headboard perpendicular to the luff, shall not exceed four inches (4").
5. Windows are allowed in mainsail. One per sail, no larger than 300 sq. in. located in lower half of sail only. The intent of this ruling solely to improve visibility and reduce the danger of collision.
6. Section 16, Paragraph b. of the By-Laws prohibits the so-called "shelf foot mainsail," or any other mainsails similarly designed or contrived, wherein an extra panel of sail cloth is added for the purposes of obtaining a sail foot surface laying roughly parallel to the deck to achieve the effect of a loose footed mainsail.
7. Mitre cut mainsails are permitted, provided that all dimensions and other
requirements in the plans and specifications are adhered to.
8. The placement of a grommet within the boundaries of the main sail plan for the purpose of a cunningham is permitted.
1. Shall measure no more than 12' 2 1/2" along the luff, 10' 1" along the leech, and 5' 3" along the foot. The jib luff wire, if any, shall not exceed 12' 3 1/2" in length between the inner ends of thimbles, grommets, rings, or similar devices. A tolerance of minus 4" is allowed in these dimensions.
a. Head to midfoot measurement of jib---the distance between the head of the sail and lowest edge of the sail at the mid-point of the foot shall not exceed 11' 3". The mid-point of the foot shall be determined by the tack cringle over the clew and tensioning both halves of the foot equally. The head to midfoot measurement shall be taken as a straight line measurement with just sufficient tension to remove the wrinkles along the line measurement.
2. Corner to corner dimensions of the jib shall be measured in a straight line as follows:
a. Luff length between the highest point of the sail material, including bolt rope, if any, at the head and the lowest point of the sail material, including bolt rope, if any, at the tack.
b. Foot length between the most forward point of the sail material, including bolt rope, if any, at the tack and the aftermost point of the sail material at the clew, including bolt rope, if any.
c. Leech length between the lowest point of the sail material directly under the clew, including bolt rope, if any and the highest point of the sail material, including bolt rope, if any, at the head.
3. Cross measurement of jib - this shall be determined by the same method used in measuring cross point of mainsail, and this measurement shall not
exceed 2'8" in a straight line, including bolt rope, if any.
4. Windows are allowed in jib. One per sail no larger than 200 sq. inches, located in lower half of sail only. The intent of this ruling is solely to improve visibility and reduce the danger of collision.
5. The jib must be fitted to the jibstay with snap hooks or piston hanks. No other devices are permitted.
1. Weight of cloth to be no less than 0.75 ounces per yard of 28 1/2" width. Luff and leech to measure 13.75 feet. Foot to measure 8.2 feet. Tolerances as described below.
2. Measuring - Measurement of spinnaker to be made by folding sail in half, luff to leech, clew to clew, and the following dimensions found as described:
Measurement C, 3' 3 5/8", plus or minus 2", taken between two points found as follows:
A, from underside of swivel, 3'6" down luff and leech. No tolerance allowed in this dimension.
B, from underside of swivel, 4'1 1/4" down the opposite side of sail as folded. No tolerance allowed in this dimension.
Measurement Z, 4'9", plus or minus 2", taken between two pints found as follows:
X, from underside of swivel, 6' 10 7/8" down luff and leech. No tolerance allowed in this dimension.
Y, from underside of swivel, 7'6" down opposite side of sail as folded. No tolerance allowed in this dimension.
Measurement P, 4' 1 1/4", plus or minus 2", taken between two points found as follows:
D, from underside of swivel, 13' 9", plus or minus 4", down luff and leech to clew.
L, from underside of swivel, 13' 10" plus or minus 4", down opposite side of sail as folded to foot.
Each line of measurement (except L) to be pulled as free of wrinkles as possible while that dimension is being measured. All three measurements of each of the triangles A-B-C, X-Y-Z and D-L,F respectively, to be taken simultaneously, and without regard for position of rest of sail. All nine measurements to be taken without intervening opportunity for the stretching or shrinking of any dimension, and in a straight line, not measuring, around contour.
3. "Venturi" type spinnakers are not allowed.
4. All Blue Jay spinnakers must have boat numbers in letters at least 9 1/2" high in accordance with USSA Rule #25E.
5. The spinnaker halyard proper may be led through either a small block or an eye-strap on the mast, then to a cleat on the mast below the color band, or to a cleat on the deck just aft of the mast, or on the forward face of the cockpit coaming, or down through the deck to a block on the mast, mast step, or centerboard trunk, then to a cleat on the forward or after end of the centerboard trunk. No other exceptions or uses of the spinnaker halyard are allowed.
a. The actual pattern of fittings is optional. However, they must equal and serve the purpose of those indicated on the plans.
b. The position of chain plates and points of attachment of stays to hull shall be shown on plans. Fittings may be galvanized or plated, made of iron, steel, bronze, brass, copper, aluminum or any alloy made basically of combinations thereof, but not of other lightweight materials, except as specifically provided for herein. Plastic or aluminum main halyard sheaves, plastic shell and sheave blocks, plastic cam cleats and plastic cleats are permitted, and aluminum brummel hooks. Carbo blocks are permitted.
c. Aluminum alloy hardware fittings, but not fastenings, are permitted provided their use does not reduce weight of hull below the minimum required by Paragraph 5 of the By-Laws.
d. Lifting eyes, rings, or shackles must be provided, but must be solely
functional and not exceed size, weight, or shape required for lifting the boat.
e. Cam cleats and winch on centerboard trunk cap for mainsail and jib sheets are permissible.
f. The plans show a single fixed spinnaker pole fitting on mast, which prohibits the use of adjustable fitting. Locations shall be at owner's option. Per Section 16.c., pole fitting not to project more that 1 1/2".
g. Spinnaker sheet leads through the deck are optional.
22. SAFETY EQUIPMENT
a. While racing, each boat must carry the following:
1. 4 lb., Danforth or equivalent anchor, or 10 lb. standard anchor.
2. 50 ft. 3/8" diameter manila, or 1/4" nylon anchor line.
3. U.S.C.G. approved vest-type life jacket for each crew member.
4. Bailing equipment--10 qt. non-collapsible bucket. Sponge and pump optional.
5. 4 ft. paddle.
6. Life jackets must be worn and properly closed in all weather conditions on Blue Jays racing in the Blue Jay Nationals and other Class-sponsored races.
b. Pumps and Bailers.
1. Hand-operated pumps may be installed in the forward part of the hull, with a discharge hose draining out over the deck or through the center-board trunk.
2. So-called "self-bailers" are permitted, limited to types with positive automatic in-flow prevention and positive locking capability, two only per boat, installed port and starboard approximately amidships, and gasketed to assure watertightness. The Executive Committee expressly authorizes the Chief Measurer to summarily reject, as he sees fit, any bailer at any time for reasons of safety and inadequacy.
3. Transom plugs are permitted.
c. Flotation. Additional flotation material may be added to all boats at owner's option. The following options are permitted in order to make the
Blue Jay easier to right and drain after capsizing or swamping.
Option I - Watertight bulkheads, one to each side, may be installed approximately 6" inboard from and running parallel to the topsides, and joining in a V under the foredeck. (This method can be used on either wood or fiber glass Blue Jays fairly easily.)
Option II - A separate floor may be installed approximately 5" above the existing inner bottom forming a watertight seal with access to the centerboard pin. Transom flap bailers may be used and floorboards may be eliminated.
A slight down-ward pitch in the sole aftward is recommended.
Option III - Airbags under deck.
The following interpretations are included for clarity:
1. Where side tank flotation is used, tanks may be terminated just forward of the cockpit at builder's option.
2. Where watertight floor flotation is used, it is understood that stated height of approximately 5" is intended as a guide only, and that any reasonable departure from it to achieve the "self-bailing" goal is permissible.
(It should be noted that because the floor must pitch downward aft to have this method work, it would be impossible to set a single height, and that the need to keep crew weight as low as possible will "self police" any tendency to raise the floor unreasonable high, which would be self-defeating. The Chief Measurer will exercise his authority in this if any problem arises.)
3. Local fleets may, at their option, restrict the right of re-enter into a race after capsizing of Blue Jays with one of the "self-bailing"setups, if it seems necessary, in order to equalize competitive factors.
4. Access holes in flotation tanks are permitted if flanges are securely through bolted and if screw-on type lids are used, properly secured against non-functional opening. Tanks should have drain holes, properly plugged, to handle condensation and random leaking.
