NYYC Cruising Rule
The New York Yacht Club's Cruising Rule (NYYC CR) is a simple rating rule for cruising yachts characterized by vintage design or a substantial bias toward cruising. It is a formula-based rule that uses owner-furnished measurement data. It produces a single-number rating that is used in time-on-distance scoring. If a yacht is considered to be more racing oriented than intended for the Cruising Rule, it may be requested to consider entering another Non-spinnaker Division such as IRC-NS. The Technical Committee has established screening values of sail-area-to-displacement and displacement-length ratios that assist in determining whether a yacht is eligible for the Cruising Rule. Please refer to the Restrictions & Racing Rules of Sailing (RRS) Modifications and the Owner's Statement on the Cruising Rule application.

New York Yacht Club Cruising Rule
Rating in S/M = 2340/R^.5 + 183; R = RF * ((.98L) + (1.32 * SA^.5) - (1.5 * DSP^.333) + (DrC)); where SA = ((JMF * LPF * I * J)/2 +MMF*MSA*.96/LPF+ .4 * MZA) * ((Max of I or P)/(J + E + E2))^.3; and LPF=1+0.4(LPJ-1) where LPJ=LP/J expressed as a fraction; and L = greater of (1.05 * LWL) or (LOA + 3LWL)/4; DrC = (Rated draft - Base draft) *(1 if positive or 0.5 if negative or 0 for fin with bulb or wing if negative); and RF = Prop Factors * Keel Factor * Mast Spreader Factor. Prop Factors are: In Aperture .975; Exposed Shaft .99; Sail Drive .985; Off Center .99; 2 Blade Fold/Feather 1.01; 3 Blade Fold/Feather 1.00; Solid 2 Blade .975; Solid 3 Blade .95; Outboard 1.02; Twin Screw .96. Keel factors are: Fin 1.02; Full .975; Center Board .96; Drop Keel 1.03; Fin with bulb or wing 1.03. Mast/Weight Factors are: Wood .98; Aluminum 1.00; Carbon 1.01; No. of pairs of Spreaders: Zero .98; 1 or more 1.00. Ec = .5 * E + .75 * GM + .5 * GU; Base draft = (0.15 * LWL + 1.5)FT; Rated draft = Draft(keel) or Draft(CB); Draft(CB) = Up + .5*(DN - UP)^2/DN; Sail Material Factors: Mainsail (MMF = 1.00 if Woven; 1.02 if Laminated Cruising; 1.04 if Laminated Racing); Jib (JMF = 1.00 if Woven; 1.03 if Laminated Cruising; 1.06 if Laminated Racing). Other sails MF=1.00 if woven. Honorary Winners Penalties: 2% for first, 1% for second based on overall season performance.
