Question 1
Rule
87 allows sailing instructions to change class rules when the change is permitted in the class rules, or when written permission of the class association for the change is displayed on the official notice board. Does this also apply to ISAF classes?
Answer 1
Yes
Question 2
If the answer to question 1 is 'Yes', does this conflict with ISAF regulation 10.5 (f)?
Answer 2
No. If the rules of an ISAF class allow class rules to be changed in the sailing instructions, this will already have been permitted by ISAF under regulation 10.5(f). If an ISAF class wants to permit a class rule change for a single event, it must first obtain ISAF permission for the change.
Question 3
May an ISAF class, under rule 87, change any of its class rules in the sailing instructions?
Answer 3
No, not unless the class is part of the organizing authority, and then subject to the requirements of rule
87 and regulation 10 when applicable. See also Answers 1 and 2.
Question 4
May a national authority change a class rule without consulting the class association?
Answer 4
No. Rule
86.1(a) refers only to changes to the racing rules by national authority prescriptions. Class rules are not racing rules, and therefore a national authority may not change a class rule by prescription.
