When a boat knows that she has broken the Black Flag rule, she is obliged to retire promptly. When she does not do so and then deliberately hinders another boat in the race, she commits a breach of sportsmanship and of rule 2, and her helmsman commits an act of misconduct.

Reason for deleting Case 66: New rule 90.3(d) makes this case unnecessary.

When a boat is racing and meets a vessel that is not, both are bound by the government right-of-way rules. When, under those rules, the boat racing is required to keep clear but intentionally hits the other boat, she commits an act of misconduct.

The failure of a race committee to discover that a rating certificate is invalid does not entitle a boat to redress. A boat that may have broken a rule and that continues to race retains her rights under the racing rules, including her rights under the rules of Part 2 and her rights to protest and appeal, even if she is later disqualified.

Momentum of a boat after her preparatory signal that is the result of being propelled by her engine before the signal does not break rule 42.1.

Reasons for withdrawing Case 70: The written facts are not consistent with the diagram. The Decision should be redrafted to interpret what the ‘seamanlike’ course is for a boat in W’s position. That interpretation would be a new and important interpretation that would, under the World Sailing Regulations, require the approval of the World Sailing Racing Rules Committee.
