Revised November 2004
Refers to Class Rule 03.02.00
A1.01 To qualify as a Production Micro, Boats shall comply with following criterions:
a. A reference Boat of the production has been declared as conform to all dispositions of the Micro Rule including all those specific to the production Boats, and a full measurement sheet shall be issued by a national Micro Class measurer.
b. A managing authority is declared. This authority may be:
- an international Owners Association;
- a group of national Owners Associations;
- a national Owners association;
- a group of national Micro Class Associations (NMCA’s);
- the national Micro Class Association (NMCA);
- the International Micro Cupper Class Association (IMCCA).
d. At least ten Boats, identical to the original one shall have been constructed.
The national IMCCA representative or national Micro Class measurer may grant a temporary status of production Boat as soon as production started, provided the builder shows his intention of producing at least 10 Boats, and has the production capacity to do so. This status can be confirmed yearly by IMCCA as long as less than 10 Boats have been built.
e. The Boat of the competitor shall also be identical to the original Boat of the production.
A1.02 In case of non-conformity, believed to improve the performance, the Boat shall be classified as a "prototype" providing she complies to all the requirements of the Micro Class Rules.
In case of non-conformity, not believed to improve the performance, the owner may be given a reasonable delay to correct the non-conformity, if required.
A1.03 The managing authority may wish to alter the characteristics of the production. For such modified Boats to qualify as a production Boat the following shall apply:
a. the modification shall be approved by the National Micro Class Association, on proposal of the national measurer;
b. at least ten of such modified Boats shall have been built and sold, or a production of at least 10 Boats has started, according to A1.01.d;
A1.04 Due to the diversity of productions, they shall be spread among two Divisions: "Racers" and "Cruisers" in accordance with their characteristics.
To be ranked in Division "Racers" or "Cruisers", the characteristics of each production shall fulfil the following requirements:
Rule RACER CRUISER
Minimum weight 04.03.01 540 kilograms 560 kilograms
Maximum Mast Length 8,20 metres 7,70 metres
Maximum length of Mainsail hoist "P" 05.02.02 7,60 metres 6,85 metres
Stability at low angles 06.02.00 12,5 degrees 10 degrees
Stability at 90° 06.03.00 10 kilograms(1) 15 kilograms
Headroom 08.03.01 1,20 metre 1,25 metre
Mattresses on berths 3 3
Sink, cooker, storage Recommended Compulsory
(1) for Racers, a weight of 12 kilograms is recommended for the stability test at 90° (06.03.00).
A1.05 For both Divisions, Rigging attached to the Mast is limited to: 1 forestay, 1 pair of shrouds, 1 pair of lower shrouds, 1 backstay.
A1.06 For the purpose of Mainsail measurement and calculation, the values of Mainsail hoist "P" and Mainsail Foot "E" shall be exactly the values measured on the reference Boat.
A1.07 The International Commission establishes, each year, the list of production Micros qualifying under Division "Racers" or "Cruisers" after proposal by each National Micro Representative.
A1.08 Micro Boats built in a production of more than 50 Boats at 1st January 1988 and ratified as "Racer" or "Cruiser" division shall be maintained so, even if one of their characteristics, being hard to modify, should not be conform to the new regulations.
A1.09 Building of a production Boat by an individual is permitted, if the plans are published, available on the market, and a production of at least 10 Boats is intended.
A1.10 If the production is already ratified, building by individuals shall be authorised by the managing authority. Boats having been built that way shall be strictly conform with the characteristics and prescriptions of the managing authority, and shall obtain a measurement Certificate issued by the official measurer of its national Micro Class association.
A1.11 For new productions, scheduled to be built by individuals, a detailed plan shall be submitted to the National Micro Class association, which will measure the first Boat built, and establish a Specifications Sheet, specifying particularly the Division together with a measurement form attesting the conformity of each Boat.
A1.12 Buoyancy
a. All production Boats from commercial manufacturers built after December 31st, 2004 shall have the buoyancy installed by the manufacturer and controlled on the reference Boat by a national measurer before being granted the status of production Boat.
b. For some old Boats in "Cruiser" and "Racer" Divisions, the required buoyancy cannot be reached according to Section 7 (07.00.00). Inflatable buoyancy volumes may be accepted provided they are installed as mentioned on the Measurement Certificate of the reference Boat. This should ensure the Boat floats in a normal position when flooded.
