Revised August 2016
CONSTITUTION OF THE ASSOCIATION
1.1 Title. The full title of the Association shall be:
- “THE KESTREL OWNERS’ ASSOCIATION”.
1.2 Aims & Objectives.
- The aims and objectives of the Association shall be to govern class racing,
further the interests of the Class and govern the affairs of the Class.
All monies received by the Association shall be devoted to these aims and objectives.
- On payment of the annual subscription, membership shall be open to all Kestrel owners. Those members who meet the statuary age of retirement may qualify for the Senior Membership. All rights and privileges of a full Member shall be retained. Other persons genuinely interested in the class may be eligible for Associate Membership. Applications for Associate Membership must be supported by three members (owners) who shall state the grounds on which membership should be granted. The normal grounds will be either past ownership, club ownership, or regular crewing. Both types of members shall be entitled to attend general meetings; however, only full members of the Association shall vote upon matters affecting the Rules and Constitution of the Association. Associate members will receive only the newsletter. The Committee may from time to time elect Honorary members at their discretion. Joint owners may each become full members on payment of the full subscription if they so wish.
- The annual subscription for members (owners) in the United Kingdom, for members overseas and for Associate Members shall be such sums as the General Meeting shall decide.
- The affairs of the Association shall be managed by a Committee consisting of a Chairman, Honorary Secretary, Honorary Treasurer, and a minimum of two members, all of whom shall be elected at the AGM. and Technical Advisors who may be nominated by the Committee.
- If, by the death or resignation of any member of the Committee, a casual vacancy occurs, the Committee may co-opt, by a majority vote, any member of the Association willing to fill the vacancy and may repeat this process for each vacancy so occurring. Members co-opted to fill such vacancies shall be entitled to full voting rights and shall be eligible for re-election. Co-opted members must be either re-elected or replaced at the following AGM.
- The Committee may, at any time, invite any members or non-members to attend its meetings for any special purpose. Such persons shall not be entitled to vote.
(d) At an Annual General Meeting or an Extraordinary general Meeting the Chairman shall have no vote except a casting vote in the event of a tie.
- The Honorary Secretary shall be responsible for the keeping of the Minutes of Committee and General Meetings, a register of members and other relevant records. He shall also be responsible for communicating the decisions of the Committee and to members, other interested individuals and organisations. The Honorary Treasurer shall have charge of the funds of the Association, making payments as authorised by the Committee. He shall keep a record of the Association’s financial affairs and shall produce a Balance Sheet (audited by an Auditor appointed by the Committee) at the AGM. The Association’s financial year shall end on the 30th September in each year. The Association encourages the formation of overseas branches of the Association.
- The AGM of the Association shall be held concurrently with, and at the venue of, the National Championship, on a day fixed by the Committee.
- Not less than 14 days notice, which shall include the agenda, shall be given of an AGM or an Extraordinary General Meeting and items for the agenda shall be submitted by members not less than 2 calendar months before the AGM.
- The Secretary shall call an Extraordinary General Meeting on the direction of the Committee or on receipt of a written request signed by at least 12 members of the Association stating the purpose for which the meeting is to be called. Such a meeting shall be held within 28 days of it being called. Only that business may be transacted for which the meeting was called.
1.7 Postal Ballots.
- The committee may decide to consult all members on specific points from time to time and may hold a postal ballot. Each member must be sent the necessary papers at their last known address and the Secretary must certify to the Committee that all members have been circulated. Overseas members should be circulated by air mail. At least 3 weeks must be allowed from the time of posting of the last circular before the votes are counted. All votes arriving after this time will be void and the remainder will be considered as abstentions.
1.8 Alteration Of The Constitution.
- Any alteration of this Constitution requires a two-thirds majority at a General Meeting or by postal ballot.
- These rules are intended to fulfill a number of purposes:
- To define the Kestrel One Design, by establishing certain measurements.
- To maintain a high standard of construction, quality and strength at moderate cost by enforcing adherence to this definition.
- To control development and to encourage refinements that tend to improve standards of quality, strength or functional efficiency and performance while preventing modification that would tend to change the character of the Kestrel or increase cost.
- The rules that follow relate to the protection of the Kestrel One Design. They specify certain conditions of manufacture and the controlling measurements of hull and spars. The intention is met by prohibiting any Kestrel from taking part in yacht racing under RYA and ISAF rules unless it carries a Measurement Certificate stating that it complies with Class Rules controlling aspects of the boat over which the owner has some choice of design. In addition the Class Committee may modify rules from time to time to allow or prevent certain lines of development.
- From the 1st January 1968, all new boats will be measured before delivery to the owner. Older boats will be certified for racing under the rules from 3.2.1 to 5.5. However, it should be understood that at meetings organised by the Kestrel Owners’ Association, competing boats, particularly the leaders, may be disqualified if they do not conform to ALL the Class Rules. This power of the Committee will be used with sensible restraint. It is not intended to oblige owners to modify their boats to match improvements in design detail in the latest boats. A boat ‘legal’ at the time of manufacture will never be outlawed for the continued use of once standard but now prohibited fittings.
3.1 Control of Construction and Protection of One Design.
- The One Design character of the Kestrel and the quality of these boats shall be controlled by limited building rights to selected builders in each country from which application is made to the Copyright Holder (Ian Proctor Designs Ltd) and the Class Builder (Richard C Hartley). Licences to build shall not be granted without the authority of the Copyright Holder (Ian Proctor Designs Ltd) and the Kestrel Owners’ Association. The copyright holder shall be responsible for issuing such licences or building rights, with the approval of the Kestrel Owners’ Association.
- No boat shall be entered on the Class Register as a Kestrel, or be eligible for a certificate as a Kestrel, unless the hull shell and other component mouldings are produced by a builder approved by the Class Association and entered on the Association Register of Builders. No boat built of reinforced plastic shall be entered on the Class Register as a Kestrel or be eligible for a certificate as a Kestrel, unless built to the official plans and specifications from the component mouldings produced on officially measured, approved and numbered moulds issued on the authority of the Class Association and entered on the Register of Moulds. All such moulds are to be produced from master ‘plugs’ held at a central source.
- In the rules that follow, tolerances are allowed to accommodate minor building errors or distortion from age, but any intentional deviation from the design or exploitation of the tolerances is prohibited. If the Measurer of a boat considers that there has been any attempt to depart from the design or the spirit of the Rules, he must report the matter to the Class Secretary who is to withhold a certificate pending an examination of the case by the Class Committee, who may at their discretion grant or withhold a Certificate. Any boat constructed wholly or partly from material other than reinforced plastics may be eligible to be registered. The Kestrel Owners’ Association should be consulted before construction.
3.2 Hull Measurements.
3.2.1 Hull Shape.
- The hull is to be chocked level and vertical athwartships and with the transom vertical. The hull shape is to be checked by means of the official templates placed 25 mm, 915 mm, 2438 mm and 3963 mm forward of the transom. The templates are to be vertical and square to the centreline of the hull. At no place shall the hull surface be more than 13 mm from the inside edge of the template.
|3.2.2||Length: overall, excluding fittings.||4763||13|
|3.2.3||Beam: 2134 mm forward of the transom
|(a) Outside transom to forward end
|(b) Outside transom to after end
|(d) Outside transom to pivot
|(a) Length from stemhead to aft edge 76 off entreline.
|(b) From stemhead to projection of aft edge of gunwale (Mk 1/2 Kestrels only)||2235||13|
|(a) Height above the skin, 152 off centre line.
|(c) Distance, outside transom to aft edge
|3.2.7||Mast Step: Height of upper surface above inside of skin.
|(Boat numbers below 138 do not need to comply with this rule).
|Rules 3.2.2 to 3.2.7 are considered once in a lifetime measurement and are guaranteed by the builder and should not require re-measuring.|
- To be made of brass, stainless steel or other alloy and fitted on both sides of the centre case slot. It shall be not less than 5 mm thick, 13 mm wide and a minimum length of 1308 mm.
Mk 1&2 Kestrels may have the stemhead to centre case and the centre case to transom keelbands removed as long rule as 3.2.9 is not infringed.
3.2.9 Hull Weight.
- Mk 1 & 2 Kestrels.
- Boats that require a weight check may be weighed with the following fittings included : keelband, bow-plate, spinnaker and foresail fairleads with cleats, centreplate cleats and blocks, mainsheet traveller, rudder hangings, hatch covers, self bailers and toe-straps. The minimum weight will be 120.2 kg. All boats after No 100 were weighed at the factory on completion of manufacture. Regardless of the actual weight of the boat, it is absolutely forbidden to reduce the weight by cutting away any of the glass fibre parts of the boat. Only the minimum material is to be removed for the fitting of self bailers, hatch covers and the like. The maximum total aperture in the foredeck for the sole purpose of stowing the spinnaker shall not exceed 54842 sq. mm. The maximum total aperture in the transom for transom scuppers and through the transom tiller shall not exceed 61294 sq.mm.
- Kestrel 2000:
- On completion of manufacture the Kestrel 2000 will be weighed and the builder will sign a declaration stating that the hull conforms to the minimum bare hull weight of 120 kg. This may include up to 3.6 kg of corrector weights (including fixings) with a maximum of two weights which will be bolted to the underside of the thwart. The number of weights fitted and their weight will be entered on the Measurement Certificate by the Class Secretary on receipt of the declaration by the builder. The total corrector weight (including fixings) will be stamped on the Kestrel plaque fixed to the inside of the hull near to the transom. It is absolutely forbidden for the corrector weights (including fixings) to removed, moved or changed in any way.
3.2.10 Class Number:
- The class number is to be clearly visible, permanently inscribed, stamped or fixed to the inside of the hull as low and as near to the centre line as practicable in figures not less than 13 mm high.
- The mast must conform to the official drawing on page 18, be of light alloy and may be either Proctor ‘D’, Proctor Cumulus or Super Spar M7 (or the equivalent in characteristics and strength, subject to the prior approval of the committee).
- It is essential that wherever the mast foot is actually placed, the shroud plates will be fixed to the skin of the hull at deck level not less than 305 mm aft of mast step.
- Mast bend fore and aft may be controlled by fixings at gooseneck level or below provided that sideways bend is not restricted other than by mast gate and spreaders.
- Shall be of light alloy, Proctor 2628 or Super Spar B1 (or the equivalent in characteristics and strength subject to prior approval of the committee).
Owners of boats which prior to 1st January 1985 had been provided with any boom sections legalised under an earlier version of the rule may continue to use them and replace like with like.
- Shape and hole positions must conform to the full size templates.
- Material must be either galvanised steel or light alloy.
- The plate shall be made from a maximum metal thickness of 10 mm (excluding packing as in ‘f’ below).
- Weight is not to exceed 28 kg nor be less than 10 kg (Boats built in 1963 and earlier may use a 7 kg alloy plate).
- Non compressible stops to a minimum of 25 mm in diameter must be fitted to the horn of the plate in the hole supplied .
- The centre-plate may be packed above the keelband to ensurea better fit in the centre-plate case.
3.2.14 Spinnaker Pole ( or Jib Stick) :
- Not to exceed 1981 mm in length, inclusive of fittings.
- The manufacturer shall guarantee that the buoyancy compartments of all new boats are soundly constructed and virtually airtight. A method for establishing the adequacy of the buoyancy is described in the test below, but the manufacturer may employ any other method that ensures the equivalent results.
The buoyancy certificate remains valid for one year. In cases where the measurer is satisfied, after careful inspection, that the condition of the buoyancy tanks is sound, he may at his discretion and without a further flotation test, twice renew the buoyancy certificate for periods of one year each. Every three years and in cases where he is not satisfied either a flotation or a dry buoyancy test, as defined, is obligatory.
- Because of their large volume it is not possible to test the buoyancy tanks by total submersion. All joints and openings should be visually inspected for cracks or damage. Before the test the tanks should be checked that they do not contain water. For convenience the mast should be stepped but all loose gear should be removed. Capsize the boat until the mast is horizontal. Place sufficient ballast aboard to completely submerge the lower tank. Hold the boat in this position for ten minutes. Repeat this test for the other side tank. Right the boat, remove transom drainage bungs and place onboard a minimum weight of 180 kg (three adults standing). The boat is left in this condition until no more water flows through the drain holes. In this waterlogged condition the boat shall have freeboard all the way round. Bail the boat out, remove the tank drain bungs and note how much water emerges. Report on the measurement certificate any significant leakage - 4.5 litres is the acceptable limit.
Dry Buoyancy test:
- Each tank is to be tested. Connect manometer equipment, as shown in the sketch, to the tank drain hole. Raise a vacuum or pressure (whether a vacuum or pressure is used on the tanks make no difference to the test) of at least 152 mm on the scale. Seal and time the fall in vacuum/pressure from 127 mm to 51 mm. If less than 30 seconds or the vacuum/pressure cannot be created, the test has failed.
4.0 Rules primarily for the control of racing performance.
4.1 Measurement Certificate:
- No boat may race as a Kestrel unless it holds a current measurement certificate vouching for all the requirements listed in this section of the Class Rules. If items covered by these rules are modified or changed, a new certificate may be required. If in doubt, contact a member of the Association Committee, who will obtain a ruling.
- The Owner has a free choice of sailmaker, material, weight, colour and design except that the material must be woven. The use of exotic materials (eg. Mylar) is prohibited.
- Any one boat may have certified as eligible for racing three mainsails, three foresails and two spinnakers.
- All sails must be marked indelibly with the makers registered number and, in addition, the mainsail must bear the Class Insignia: a symbolic wing 635 mm in length on each side of the sail at an angle of 45 degrees to the mast, the thicker end downwards and forwards, together with the boats registered number according to ISAF requirements.
- The spinnaker shall also bear the boat’s registered number on the outside of the sail when being flown. Such identifying marks may be in a contrasting colour.
- When sails (mainsail and foresail) are permitted to contain a window, the foresail will now only contain one window, but the mainsail may have two.
- Because sailmakers display a variation in the way they make sails, particularly in the design of corners, it may be not be easy to establish the exact points between which measurements should be made. Alternative methods of establishing datum points are provided. The measurer should select a method that allows no unfair advantage, nor incurs any unfair penalty. Deliberate attempts to gain extra area by departing from the spirit of the rule, while conforming to the letter, should be thwarted by the measurer’s choice of method. The quoted dimensions are nominal. If the corner of the sail contains a conventional cringle (ie. when no dimension of the cringle exceeds 25 mm and it is set within the natural triangle of the sail and no more than the normal bolt rope thickness away from the edge of the sail), measurements shall be taken from the centre of the cringle. It will be seen that a sail made with 3 ‘conventional’cringles will actually be up to 38 mm longer on each side than the normal length.However, if the cringles are oversize, outside the sail or excessively inset, then measurements are to be taken from the point of intersection of an extension of the two sides, disregarding any curve.
In order not to penalise sailmakers who have perfectly proper reasons for unconventional cringle placement, a tolerance of 19 mm is allowed on each corner so constructed. In recording the dimension, the measurer is to subtract 19 mm from the actual length to that corner (38 mm for a side bounded by two such corners). All measurements are to be taken on dry sails, hauled out hand taut, with approximately 4.5 kg tension.
4.2.2 Mainsail Dimensions :
|Luff||uncontrolled, except by limit bands.||Foot||uncontrolled, except by limit bands. No part of the foot may be allowed to fall below the bottom edge of the boom.
|Leach||6401 mm |
|Width||half height (including bolt rope) 1981 mm three quarter height (including bolt rope) 1245 mm|
|Headboard||width 102 mm|
- Leach Measurement: Shall be the straight line distance between the centres of the head and clew cringles under 4.5 kg tension. Alternatively, if they are unusual in size or design, or have been placed as close as practicable to the corner of the sail, the datum points shall be taken as the highest point on the sail and the lowest point below the clew cringle.
- The Cross Measurement at Half Height: The mid point of the luff shall be determined by folding the sail upon itself with the highest point of the headboard even with the lowest point of the bolt rope extension at the tack. The mid point of the leach shall be determined in a similar fashion, with the headboard folded down to the clew cringle. The cross measurement shall be the distance between the halfway points of the luff and leach with the sail laid on the floor with just sufficient tension to remove the wrinkles.
- The Cross Measurement at Three Quarter Height: Shall be determined in a similar way by folding a second time, taking the headboard to the leach and luff at half heights fold already made. Where the tack of the mainsail cannot be clearly defined, the mid point of the luff shall be found by stretching the full length of the luff under hand tension (about 4.5 kg) and measuring down 2895 mm from the highest point of the headboard. Similarly the three quarter height point is assumed to be 1448 mm below the highest point.
- The Roach of the mainsail: Shall fall in a fair and uniform curve from the peak of the sail to the boom.
- Headboard measurement: The width of the highest point of the stiffening material inside the sail, taken at right angles to the luff, shall not exceed 102 mm. The overall width from the bolt rope to leach may well be a little more.
- Battens: The roach of the sail is to be supported by four battens, each not more than 51 mm wide. The angle of the battens relative to the leach is optional. The battens shall be positioned so that their outer ends divide the leach into five approximately equal parts. In the case of the top batten, its centre line at the leach must be exactly positioned plus or minus 25 mm. The maximum length of the battens are:
|Top batten maximum length||1219 mm|
|Lower battens maximum length||838 mm|
- The measurement refers to the length of the batten inside the sail in the working position. The width of the head of the sail, measured from the leach on the centre line of the top batten to the nearest point on the luff must not exceed 1016 mm.
- Undersize mainsails: All dimensions quoted in these rules are maximum. It is intended that owners may have smaller sails if they wish. If a mainsail:
- Measures overall less than 5334 mm in the luff and less than 2210 mm in the foot, or
- has a combined length round the bolt ropes of less than 7467 mm then the number of battens may be reduced to three, dividing the leach in four approximately equal parts. There is no requirement to measure leach length, half height and three quarter height width; however, the requirements must still be met relating to: Batten length and width; Sail material; boat number and class insignia; window and headboard.
- Windows: Two windows are permitted, but the total area must not exceed a maximum area of 186040 square mm. If two windows are fitted, one must be along the foot of the sail with its centreline halfway between the tack and the clew. If only one is fitted, then it can either be near the leach at spreader height, or along the foot in the same position asdescribed above.
4.2.3 Foresail Dimensions.
|Window: maximum area of||186040 square mm|
|Maximum roach on leach||102 mm|
|Maximum distance from head to mid point on foot 4013 mm with the foot following a fair curve through the point from tack to clew|
|The jib sizes are recommendations rather than legal restrictions and a window is permitted. The genoa rules will be applied to all foresails.|
- Battens or other means of artificial stiffening are not permitted. The luff of the genoa or jib shall be seized to the wire at the tack and head.
- The spinnaker shall be of woven material, three cornered and symmetrical, with no artificial stiffening other than the usual fabric hem, patches binding and light rope. Class numbers are to be fitted to the front of the spinnaker when being flown in any appropriate colour in figures not less than 305 mm high. All sails made to previous measurement rules are to remain acceptable for class racing. However, such sails shall be held accountable to the measurements allowed by those rules under which they were constructed. This rule does not preclude the building of new sails to previously acceptable measurement rules. Either or both of the two spinnakers allowed in the description of a sail set shall be allowed aboard the craft whist racing but only one shall be flown at a time.
4.2.5 Setting a spinnaker:
- When a spinnaker is set the pole shall be carried on the opposite side to the boom. A spinnaker shall not be set without a pole. The tack of the spinnaker that is set and drawing shall be in close proximity to the outboard end of the spinnaker pole except when hoisting, gybing or lowering. A whisker pole or spinnaker pole used to boom out a headsail may be carried on either side of the boat.
- Spinnaker Dimensions excluding North America:
Half height width not less than three quarters of foot width.
- Height. The sail is to held by the head cringle and the sail is to be under sufficient tension to remove wrinkles. No part of the fabric of the foot shall be more than 4572 mm from the highest point of the head.
- Width. Measurements shall be taken between points on the luffs at equal distances from the head. The sail shall be under just sufficient tension to remove wrinkles. The extreme distance between the outside edges of the fabric shall not exceed 2896 mm at any height. The width measurement between the mid point of each luff shall not be less than three quarters of the straight line width between the lower corners.
- Spinnaker Dimensions for North America Only:
- The sides shall not exceed 4572 mm nor be less than 4420 mm.
- The foot may not exceed 3505 mm nor be less than 3353 mm.
- These measurements should be taken under 2.3 kg.
- (This requirement is optional at the discretion of the Race Committee).
- Girths shall be measured with the spinnaker folded in half putting the two clews together and then spread evenly and put flat on the floor. Two girth measurements ‘A’ and ‘B’ shall be taken across the sail.
- Measurement ‘A’ shall be taken a point 1372 mm down the luff and leech from the top of the sail and a point 1372 mm in a straight line down the opposite side of the sail as folded, not measuring around the contour. This measurement shall not be more than 1448 mm nor less than 1372 mm.
- Measurement ‘B’ shall likewise be taken between points 2438 mm down the luff and leech and 2438 mm down the opposite side of the sail as folded, not measuring around the contour. The measurement shall not be more than 1981 mm nor less than 1829 mm.
- When measuring girths it is important that the cloth between the head of the sail and points of measurement and immediately below, be spread out only enough to smooth out vertical wrinkles, but not enough to produce transverse wrinkles.
- When a girth measurement is taken there should be no tension on the lower
corners, nor at the girth points not being measured. Class numbers are to be on both sides of the spinnaker in any appropriate colour in figures not less than 305 mm high.
- The rig shall be that of a single masted Bermudan sloop. Additionally:
- The fitting of the forestay is optional.
- There shall be no adjustment of the shrouds whilst racing.
4.3.2 Control of Sail Plan & Limit Bands:
- The height of the sail plan above the hull and the maximum extension of luff and foot of the mainsail along the spars must be indicated by distinctive contrasting limit bands.
- A band shall be located on the mast with its upper edge 1295 mm ? 13mm above the inner skin of the hull. On boats No 139 onwards in which the height of the mast step is standardised at 317 mm this band can be located 990 mm ? 13mm from the shoulder on the butt of the mast (datum point). The upper edge of the boom shall not be set below the level of the upper edge of this band whilst racing.
- A band shall be located near the head of the mast with its lower edge not more than 5791 mm above the upper edge of the band specified in (a) above. No part of the mainsail shall be hoisted above the lower edge of this band whilst racing.
- A band shall be located on the boom with its forward edge 2730 mm aft of the after edge of the luff groove when the boom is assembled on the gooseneck. No part of the foot of the sail shall be extended aft of the forward edge of this band whilst racing.
- The extended line of the forestay and the luff of the jib shall meet the mast not more than 3885 mm above band (a).
- The spinnaker halyard exit from the mast shall not be more than 4013 mm above band (a).
- The following are prohibited:
- Ballast, other than bilge water.
- Trapezes, sliding seats, or any device other than toe straps used to support the crew outboard of the hull.
- Any device increasing the water line length.
- The Committee reserve the right to prohibit any modifications which deviate from the character of the Kestrel and would strongly recommend that if an owner is in doubt about the acceptability of a modification, they should contact the Committee for discussion. Any modification approved by the Committee would be held in the strictest confidence until the owner wished otherwise. The owner, on refusal of a modification has the right to present their case at an AGM as long as the item for the agenda reaches the Secretary by the statuary time limit (rule 1.6.b)
5.0 General Rules.
5.1 Champion’s Insignia:
- Current and past holders of the National Championship shall attach to the outside of the transom a symbolic wing 64 mm long.
5.2 Racing Crew:
- The Kestrel shall be raced by two or three persons including the helmsman, unless specified in Sailing Instructions.
- In races organised by and for the Kestrel Owners’ Association, only Full or Associate Members of the Association may take the helm, except for brief emergency reasons.
5.2.1 Substitution of Crew:
- Unless the Race Committee consents to a change of helmsman or crew, a competing boat must have the same helmsman and the same crew throughout the event. If any competitor wishes to make any change in their helmsman or crew, they shall apply in writing to the Race Committee for permission to do so, specifying the reason for the change. The Race Committee will consent to the change if the specified grounds appear to be reasonable and it considers that the change is not being made primarily for the purpose of gaining an advantage.
- There is no limitation on rudder design. Owners may posses more than one rudder, but the rudder used must not be changed during a race, or during a series of races at one meeting, unless as a result of loss or breakage.
5.4 Class warning Signal:
- The Class warning Signal shall be the International Code Flag “ L”.
5.5 Measurement Form and Measurement Certificate:
- When a purchase has been finalised between the builder and owner, the builder will send to the Class Secretary a Measurement Form of Compliance. This form guarantees that the hull and weight conforms to current class rules and that a buoyancy test has been successfully carried out. It also guarantees that the boat conforms to the current EU rules concerning stability and that the boat holds an EU number. On receipt of a properly completed Measurement Form, the Class Secretary will issue a Measurement Certificate to the new owner and also return to him the original copy of the Measurement Form of Compliance. No boat is entitled to race as a Kestrel unless it holds a valid Measurement Certificate. The Certificate will specify the sails which the owner is entitled to use for racing. The maker’s registered numbers, which must appear on the Measurement Form, will be recorded on the certificate. No boat may race with sails other than those quoted. If the owner purchases a new or additional sail, the number of the new sail must be substituted on the Certificate for the sail replaced, and the replaced sail no longer used for racing. The change can be made by any Class Committee member, Official RYA measurer or an approved club measurer. The cost of all measurement falls upon the owner. The owner of the boat is responsible for ensuring the certificate is not invalidated. Change of ownership invalidates the Certificate. A replacement is supplied by the Secretary to the new owner upon presentation of the old Certificate together with the appropriate fee as determined from time to time by a General Meeting.
6.0 Class advertising for the year 2000 onwards:
- In races organised by and for the Kestrel Owners’ Association, a boat may display advertising as dictated by the rules in Section 6. Throughout an event the boat shall not display advertising of more than two organisations or persons other than those stated in 6.2.1.
- The advertising shall be one or two of the following:
- the name of an organisation or person, or
- a brand or product name, or
- a logo.
- The forward 25% of each side of the hull may display no more than two advertisements chosen by the ISAF, the national authority, or the Class Association. When more than one of the above organisations wish to use this space, they shall be entitled to half the length of the space on each side.
- The remaining length of the hull shall be free of any advertising except for that permitted in rule 6.3 and except that half that length may be used for advertising chosen by the boat. If advertising is not displayed on the sides of the hull, it may be displayed on each side of the buoyancy tanks, subject to the same length dimensions.
- One builders mark, which may include the name or mark of the designer
may be placed on the hull, and one makers mark may be displayed on the spars and on each side of small equipment. Such marks shall fit within a 150 x 150 mm square.
6.4 Advertising on sails:
- One sailmakers mark, which may include the name or mark of the
sailcloth manufacturer and the pattern or model of the sail, may be displayed on both sides of the sail and shall fit within a 150 x 150 mm square. On sails other than spinnakers, no part of such mark shall be placed farther from the tack than the greater of 300 mm or 15% of the length of the foot.
