Case 21
Definitions, Mark-Room
Definitions, Room
When a right-of-way boat is obligated to give mark-room to a boat overlapped inside her, there is no maximum or minimum amount of space that she must give. The amount of space that she must give depends significantly on the existing conditions including wind and sea conditions, the speed of the inside boat, the sails she has set and her design characteristics.
Case 22
Rule 61.2(d), Protest Requirements: Protest Contents
Rule 63.5, Hearings: Validity of the Protest or Request for Redress
Rule 64.2, Decisions: Penalties
It is not relevant to the validity of a protest that a rule the protestor believes was broken is not one of the rules that the protest committee later determines to have been broken.
Case 23
Definitions, Obstruction
Rule 10, On Opposite Tacks
Rule 14, Avoiding Contact
Rule 19, Room to Pass an Obstruction
On a run, rule 19 does not apply to a starboard-tack boat that passes between two port-tack boats ahead of her. Rule 10 requires both port-tack boats to keep clear.
Case 24
Definition, Room
Rule 11, On the Same Tack, Overlapped
Rule 12, On the Same Tack, Not Overlapped
Rule 15, Acquiring Right of Way
Rule 43.1(b), Exoneration
When a boat becomes overlapped to leeward from clear astern, the other boat must act promptly to keep clear. When she cannot do so in a seamanlike way, she has not been given room as required by rule 15.
Case 25
Definition, Mark-Room
Rule 11, On the Same Tack, Overlapped
Rule 14, Avoiding Contact
Rule 16.1, Changing Course
Rule 18.2(b), Mark-Room: Giving Mark-Room
Rule 43, Exoneration
After an inside overlapped windward boat has been given mark-room, rule 18 no longer applies, but rule 11 continues to apply. The inside windward boat must keep clear of the outside leeward boat, and the leeward boat may luff provided that she gives the windward boat room to keep clear.
Case 26
Rule 14, Avoiding Contact
Rule 16.1, Changing Course
Rule 18.1, Mark-Room: When Rule 18 Applies
Rule 43.1(c), Exoneration
Rule 64.2, Decision: Penalties
A right-of-way boat need not act to avoid a collision until it is clear that the other boat is not keeping clear. However, if the right-of-way boat could then have avoided the collision and the collision resulted in damage, she must be penalized for breaking rule 14.
Case 27
Rule 2, Fair Sailing
Rule 13, While Tacking
Rule 14, Avoiding Contact
Rule 15, Acquiring Right of Way
Rule 43, Exoneration
A boat is not required to anticipate that another boat will break a rule. When a boat acquires right of way as a result of her own actions, the other boat is entitled to room to keep clear.
Case 28
Rule 28.1, Sailing the Course
Rule 32.1, Shortening or Abandoning After the Start
Rule 43.1(a), Exoneration
Rule A5, Scores Determined by the Race Committee
When one boat breaks a rule and, as a result, causes another to touch a mark, the other boat is to be exonerated. The fact that a starting mark has moved, for whatever reason, does not relieve a boat of her obligation to start. A race committee may abandon under rule 32.1(c) only when the change in the mark's position has directly affected the safety or fairness of the competition.
Case 29
Definitions, Obstruction
Rule 19.2(b), Room to Pass an Obstruction: Giving Room at an Obstruction
Rule 19.2(c), Room to Pass an Obstruction: Giving Room at an Obstruction
A leeward boat is an obstruction to an overlapped windward boat and a third boat clear astern. The boat clear astern may sail between the two overlapped boats and be entitled to room from the windward boat to pass between her and the leeward boat, provided that the windward boat has been able to give that room from the time the overlap began.
Case 30
Definitions, Keep Clear
Rule 14, Avoiding Contact
Rule 19, Room to Pass an Obstruction
Rule 43, Exoneration
A boat clear astern that is required to keep clear but collides with the boat clear ahead breaks the right-of-way rule that was applicable before the collision occurred. A boat that loses right of way by unintentionally changing tack is nevertheless required to keep clear.
