Summary:
In a fleet race either for one-design boats or for boats racing under a handicap or rating system, a boat may use tactics that clearly interfere with and hinder another boat's progress in the race, provided that, if she is protested under rule 2 for doing so, the protest committee finds that there was a reasonable chance of her tactics benefiting her final ranking in the event. However, she breaks rule 2, and possibly rule 69.1(a), if while using those tactics she intentionally breaks a rule.
Facts for Question 1:
In a fleet race for one-design boats, boat A uses tactics that clearly interfere with and hinder boat B's progress in the race. While using those tactics, A does not break any rule, except possibly rule 2 or rule 69.1(a). B protests A under rule 2.
Question 1:
Answer 1:
In circumstance (a), A would be in compliance with recognized principles of sportsmanship and fair play.
In circumstances (b) and (c), A would break rule 2, and possibly rule 69.1(a).
In circumstance (d), both A and C would break rule 2, and possibly rule 69.1(a). In addition, by receiving help prohibited by rule 41 from A, C would also break rule 41.
In circumstance (e), A would break rule 2, and possibly rule 69.1(a) because, with no good sporting reason, her actions would clearly break recognized principles of sportsmanship and fair play.
Question 2:
Would Answer 1 be different if the boats had been racing under a handicap or rating system and if A had been faster or more manoeuvrable than B?
Answer 2:
No.
Question 3:
Would Answer 1 be different if, while using tactics that clearly interfered with and hindered B's progress in the race, A had intentionally broken a rule?
Answer 3:
Yes. Whenever a boat intentionally breaks a rule, she also breaks rule 2, and possibly rule 69.1(a).
