B. IC37 Rules Questions and Interpretations
1. Do I need to be a Class member if I intend to helm while racing?
A Principal Helmsperson and Substitute Helmspersons must be Class members in good standing. See Class Rule C.2.1 for definitions and certain exceptions.
2. Can Sail Limitation Marks (SLMs) from last year be used again this year?
SLMs are valid only for one year of issuance. See Class Rule H.2
3. Is the crew size determined by the number of crew or total crew weight?
There is no limitation on the number of crew. Maximum total crew weight is 686kg (1512.6lbs). Crews of 8 or more must have 2 persons of the opposite gender. Crews of 7 or less must have one person of the opposite gender. See Class Rules C.2.2 and C.2.3.
4. Can a team race with a junior sailor (who’s weight does not count towards total crew weight) during the Nationals or North Americans?
No, in A Regattas, Class Rule H.3.2.a.3 states: all crew must conform to the crew requirements including the total allowable weight, regardless of age.
5. Can a team adjust rig tension, forestay length or mast butt location after being inspected by the Class or during an event?
No, See Class Rule C.9.3 and C.9.6
Additionally, the rig cannot be changed after the class measurer has checked and sealed the rig. If there is a question on rig tune the class measurer may elect to double check the rig, fine tune and re-seal but only prior to the start of the first race of the regatta. Once racing commences the rig may not be changed except for repairs needed due to racing altercations, storm damage, etc. and must be approved, measured and sealed by the class measurer.
