Section 1. The measurement of all Classic Moth Boats shall be as described in the Enclosure of Specifications.

Section 1. The Classic Moth Boat Association (CMBA) has divided the fleet into three divisions for the class Nationals and Midwinters. In general Mothboat designs with low wetted surface (and to a lesser extent, narrow waterline beam) are significantly faster and race in a separate Gen II division. Slower designs race in the Gen I division. Vintage Mothboats, those which meet the Vintage measurement rules in the Enclosure of Specifications, race in the Vintage division.

Section 2. Classification of hull designs to Gen I and Gen II divisions will be determined by a Classification Committee. The Classification Committee is tasked to classify all new Mothboat designs as Gen I or Gen II; and to review and if needed, reclassify designs that have been extensively modified. The Classification Committee will consist of three class members: two class members in good standing, who will stand for election at the class annual general meeting (AGM), and the Chief Measurer. Classification Committee decisions will be majority vote (2/3). A quorum for the Classification Committee is two. If a member of the Classification Committee has a Moth boat under review by the Classification Committee, that member will recuse himself/herself from voting on the classification.

Section 3. The following Mothboat hull designs are considered Gen II: Duflos, Mistral, Stockholm Sprite, Skol, Swiss Moth, Tweezer. All other Mothboat hull designs not listed in Gen II specifications, or qualified to race under the Vintage Divison are Gen I. All new Mothboat designs or radically modified Mothboat hull designs are considered Gen II until classified by the Classification Committee. A builder or designer may apply to the Classification Committee for pre-­‐approval of a Gen I classification. A temporary Classification can be issued at the beginning of a regatta, before formal review by the Classification Committee, with the approval of all competitors. Any class member of good standing can request a reclassification as an order of New Business at the class AGM. Approval by the majority of class members at the AGM will override any Classification Committee ruling.

Section 4. Local Regatta Organizers may use the Classification Divisions at their discretion and may modify them with approval of the competitors.
