1. Interpretation: Specifications, however complete cannot anticipate every possible situation that may arise. If a point is not specifically covered, a ruling may be obtained from the Class Measurer. In interpreting these Rules and Specifications, the Class Measurer shall consider the drafting intent as well as any technical construction that might be derived from the wording and shall bear in mind at all times the basic principle of the specifications which is to maintain the Northern Michigan Sloops as a One Design Class. Nothing in these rules and specifications in optional unless so stated. In the absence of specific class rule statements to the contrary, The Racing Rules of Sailing, The Equipment Rules of Sailing, and the Prescriptions of USSAILING shall apply.

2. Standards: The original plans for the Northern Michigan Class, dated January 5, 1934, by Russell J. Pouliot shall constitute the standard plans for the Class.

3. Eligibility: It shall be the responsibility of the Governing Committee to insure that individual boats that seek to race in the fleet abide by these rules and specifications.

It shall be the responsibility of each owner to insure that his boat complies with the letter and spirit of these rules. An NM may be challenged for infringement of these rules by an association member via a protest in writing stating the grounds thereof, submitted to the Fleet Captain who shall investigate, and promptly call a meeting of the Governing Committee for decision, which may direct corrections to the boat, or take other actions up to and including declaring the boat ineligible to participate in NM Class Events.
