INTRODUCTION
1.1
The 5000 was created as a strict one-design dinghy where the true test when raced is between crews and not boats and equipment. The fundamental objective of these 5000 Class Rules ("the Rules") is to ensure that the strict one-design concept is maintained.
1.2
The English text of the Rules shall govern.

For advertisements on the genniker, an advertising panel made from sailcloth equivalent to that used in the construction of the sail may be sewn to the genniker below the horizontal seam of the sail and may be inserted into the genniker (ie material removed from behind it). The inserted panel should not be larger than 2.5 metres in area, or closer than 0.75 square metres to any edge, or closer than 0.2 metres from the horizontal centre seam and should not change the aerofoil shape of the sail w) the cunningham line may be led to cleat 5107 via block 5108 and block 5109 and the vang led to cleat 5308 via block 5307 (see diagrams 1and 3)
4.5
Repairs and preventative maintenance to hull, mast, boom, racks, spinnaker pole, sails, battens, centreboard, rudder system, tiller, fittings, equipment, standing rigging and running rigging may be carried out without violation of these Rules provided such repairs are made in such a way that the essential shape characteristics or function of the original are not affected.
4.6
Preventative maintenance shall include the replacement of fastenings with alternatives provided that the equipment is replaced in the original position and in accordance with these Rules where relevant.
4.7
Waxing and polishing of the hull is permitted but sanding is not allowed unless for the purposes of a repair. Complete sanding and refinishing of the hull with the intention or effect to lighten the hull or improve the performance, finish or shape is not permitted, but nothing shall prohibit the repainting of a hull which requires refinishing.

MEASUREMENT
5.1
The 5000 shall conform to these Rules. All the equipment listed in the Equipment List included in Appendix 1 shall be carried in the position as supplied by the Builder and the 5000 shall be rigged in accordance with the Rigging Diagrams in Appendix 1. In the case of a measurement dispute not explicitly covered by these Rules, the procedure set out in paragraph 5.2 shall be adopted.
5.2
A sample of 5 sailboats or, if appropriate, a sample of 5 items, not the subject of the measurement dispute, shall be taken and measured using identical techniques. The dimensions of the disputed sailboat or item shall be compared to the measurements taken from the sample and if the sailboat or item is outside the maximum or minimum dimensions obtained from the sample, the matter together with details of the measurement methods and any other relevant information shall be referred to the Chief Measurer of the Class Association whose decision shall be final and binding on all parties.
5.3
In the event of a dispute alleging non compliance with these Rules, the matter, together with any relevant information shall be referred to the Chief Measurer of the Class Association whose decision shall be final and binding on all parties.

WEIGHT AND RIGHTING MOMENT EQUALISATION
6.1
It is the responsibility of the helm and crew to comply with the following requirements whilst racing:
6.1.1
The combined weight of the helm and crew ("CW") plus the Ballast Weights and intermediate rack tubes, if fitted, shall be not less than 170 kilograms.
6.1.2
The maximum Rack Settings shall be determined from the Rack Chart in Appendix 3 based on the CW and the combined righting moment ("CRM") of the helm and crew.
6.1.3
The total weight of all clothing and equipment worn by the helm or crew shall not exceed 12 kilograms each weighed in accordance with Appendix A4 "Weighing of Wet Clothing" of the International Yacht Racing Rules.
6.1.4
No clothing and equipment of the helm and crew shall be worn with the specific feature of adding weight by water absorption or holding water in pockets, compartments, containers or any other method.
6.2
The CW shall be determined by adding together the individual weights of the helm and crew each individual weight being rounded to the nearest whole kilogram.
6.3
The CRM shall be determined by adding together the individual righting moments of the helm and crew, measured with arms folded across the chest and legs straight in accordance with the example illustrated in Appendix 2. Each individual righting moment shall be rounded to the nearest whole kilogram meter.
6.4
Ballast Weights shall be securely fitted on the centre line between the cunningham and kicking strap (vang) cleats using the lead weights supplied by the Builder.
6.5
Ballast Weights and Rack Settings shall not be adjusted from the time the sailboat has been launched until fifteen minutes after the sailboat has come ashore or once the Chief Measurer or the District Measurer (or one of his appointed assistants) has completed a measurement check.
6.6
Any helm and crew may be required to demonstrate their compliance with the Weight and Righting Moment Equalisation Rules when requested to do so by the Chief Measurer, the District Measurer (or one of his appointed assistants), another competitor or the race committee. Check weight and righting moment measurements are to be undertaken whilst wearing the sailing clothes and personal equipment worn and carried on board during the preceding race. The helm and crew shall be immediately advised of their CW and CRM and, if they wish, may immediately request a re-measurement. The helm and crew are to ensure that their re-measurement takes place within five minutes of their request. No items of clothing or equipment may be added or removed for the re-measurement.
6.7
Where a helm and crew have completed a race, and not retired, and subsequently it has been determined that they have failed to comply with the Weight and Righting Moment Equalisation Rules, they shall be disqualified. Where the Chief Measurer or the District Measurer (or one of his appointed assistants) considers the breach of the Weight and Righting Moment Equalisation Rules to have been significant and deliberate, he shall issue a written warning to the helm and crew. A second occurrence within a period of one year will result in the helm and crew being suspended from membership of the Class Association and the matter being reported to the appropriate National Sailing Authority.
6.8
With the advance agreement in writing of the District Chairman, the weight limit specified in paragraph 6.1.1 and the Rack Settings contained in the Rack Chart in Appendix 3 may be amended for certain sanctioned events. Where the Weight and Righting Moment Equalisation Rules are so amended, the sailing instructions shall contain the amendments to the weight limit and Rack Chart.

SAILING REQUIREMENTS
7.1
The 5000 shall be raced with two persons aboard.
7.2
The helm and crew shall not race a 5000 unless they comply with paragraph 6 of these Rules.
7.3
No person is permitted to race a 5000 in any Fleet, inter Fleet, District or other sanctioned event unless the owner, or a joint owner, or a nominated representative of an organisation owning the 5000 is a current Full Member and either the helm or crew is a current Full or Associate Member of the Class Association.
7.4
Only one mainsail, one jib and one spinnaker shall be used for each series of races unless a sail is damaged beyond repair or damaged to the extent that it cannot be repaired before the start of the next race in the series in which case a replacement sail may be used. For the purposes of this rule, a series is deemed to be two or more individual races to be sailed within a period of ten consecutive days or less which count towards an overall points total.
7.5
Whilst racing, the 5000 shall be rigged in accordance with the Equipment and Rigging Diagrams contained in Appendix 1, or as varied by rule 4, and shall carry all the equipment and rigging included in those Diagrams.
7.6
