Section A: Right of way
A boat has right of way when another boat is required to keep clear of her. However, some rules in Sections B, C and D limit the actions of a right-of-way boat.
On opposite tacks
After a boat passes head to wind, she shall keep clear of other boats until she is on a close-hauled course. During that time rules 10, 11 and 12 do not apply. If two boats are subject to this rule at the same time, the one on the other’s port side or the one astern shall keep clear.
