205. Stability.
1. Limit of Positive Stability (LPS): A yacht shall not be issued a valid IMS certificate if her
IMS upper Limit of Positive Stability is less than 103.0 degrees.
2. Stability Index: As provided under IMS Regulations 201, a yacht’s eligibility for entry in
IMS races of ORC Special Regulations Categories 0, 1 or 2 may be limited on the basis of
her Stability Index as noted in the “Limits and Regulations” section of her IMS Rating
Certificate (see Appx 1). Stability Index is calculated as follows.
Stability Index = LPS + Capsize Increment (CI) + Size Increment (SI)
Where, in imperial units:
CI = 18.75*(2.0-MB/(DSPM/64)^.3333)
SI = (((12.0*(DSPM/64)^.3333+LSM0)/3.0)-30.0)/3.0
CI shall not be taken as greater than 5.0 nor less than -5.0.
SI shall not be taken as greater than 10.0
