This Week's Question

Boats S (on starboard tack) and P (on port tack), both close-hauled, are converging on a beat. P will safely cross S. However, when they are less than two lengths apart, the wind veers (shifts to the right) ten degrees. S luffs (changes her course) in response to the wind shift such that P is unable to keep clear. There is minor contact with no damage or injury, and both boats protest. You are on the protest committee; which boat should be penalized? (From Perry, Quiz 6)

Answer

Boat S is penalized under rule 16.1, Changing Course. Rule 16.1 states, “When a right-of-way boat changes course, she shall give the other boat room to keep clear.” S changes course when so close to P that P is unable to keep clear and there is contact. Therefore, S failed to give P room to keep clear, thereby breaking rule 16.1. The fact that S’s change of course is in response to a windshift is not relevant to the application of rule 16.1. P breaks rule 10, On Opposite Tacks, but is exonerated (not penalized) under rule 21, Exoneration, or rule 64.1(a), Decisions: Penalties and Exoneration, because she is compelled to break rule 10 by S’s breach of rule 16.1. S also breaks rule 14, Avoiding Contact; but as the right-of-way boat, she is exonerated (not penalized) for breaking rule 14 as the contact does not cause damage or injury (see rule 14(6)). P does not break rule 14, because S changes course so close to P that it is not possible for P to avoid the contact

This Week's Question

The race committee displays flag U as the preparatory signal. At the start, several boats are OCS (on the course side of the starting line) including Boat X. The race committee signals a general recall and restarts the race. Boat X starts cleanly and wins the race, but on shore her score is posted as DSQ. She requests redress. You are on the protest committee; should X be scored DSQ? (From Perry, Quiz 51)

Answer

The race committee acts improperly when it scores Boat X DSQ. Rule 30.3, U Flag Rule, states that a boat shall not be disqualified under this rule if the race is restarted (see also rule 36, Races Restarted or Resailed). Therefore, Boat X is entitled to redress, under rule 62.1(a), Redress; and it would be reasonable to reinstate her in her finishing position in the race and move the other boats down accordingly (see rule 64.2, Decisions on Redress). Furthermore, the protest committee can call a hearing, under rule 60.3(b), Right to Protest; Right to Request Redress or Rule 69 Action, to consider redress for any other boats that were improperly scored DSQ by the race committee.

This Week's Question

Boats S and P are sailing directly downwind toward a leeward mark. They had been overlapped for several lengths with S inside and slightly ahead. As S entered the zone, she luffed (headed up). As her bow became abreast of the mark, she bore away to gybe, and there was contact, but no damage or injury. Both boats protest. You are on the protest committee; which boat should be penalized? (From World Sailing Casebook, Case 75)

Answer

P is penalized. S did nothing for which she can be penalized. At position 1, S reached the zone and P was required by rule 18.2(b) to give S mark-room thereafter. In addition, until S gybed P was required by rule 10 to keep clear of S. As S luffed, she was required by rule 16.1 to give P room to keep clear, and until she gybed S was also required by rule 18.4 to sail no farther from the mark than needed to sail her proper course. The mark-room that P was required to give S was the space S needed in the existing conditions to sail promptly to the mark in a seamanlike way. That space was a direct corridor from S1 to a position close to and alongside the mark on the required side. P gave S that room. However, because S had right of way she was not required to remain within that corridor; she was permitted to sail any course provided that she complied with rules 16.1 and 18.4. S luffed gradually through approximately 45 degrees while sailing about three lengths forward, and P made no effort to keep clear. Shortly before position 3, S needed to act to avoid P. At that moment P broke rule 10. When S luffed after position 2, if P had acted promptly there was space for her to have maneuvered in a seamanlike way to keep clear of S. Therefore, S did not break rule 16.1. When S gybed just after position 3, she had not sailed farther from the mark than needed to sail her proper course. Indeed, in the absence of P (the boat ‘referred to’ in the definition Proper Course), S’s proper course might well have been to sail even farther from the mark and higher than she did, so as to make a smoother, faster rounding and to avoid interference with her wind by being backwinded or blanketed by other boats ahead. Therefore, S did not break rule 18.4. Concerning rule 14, both boats broke the rule because there was contact and it was reasonable possible for each of them to avoid it. P is therefore disqualified under rule 14 as well as rule 10. However, S is exonerated because she was the right-of-way boat when the contact occurred and there was no damage or injury (see rule 14(b)). (From World Sailing Casebook, Case 75)

This Week's Question

At an upwind finish, two close-hauled boats on opposite tacks (S and P) are converging at the left end mark of the finishing line. When about a length and a half from the mark, P completes a tack to leeward of S without fouling her. However, in order to pass the mark on the correct side, P luffs up to almost head to wind, thereby causing S to sail above close-hauled to avoid her. S protests P. You are on the protest committee; which boat should be penalized? (From Perry, Quiz 37)

Answer

Boat P is penalized for breaking rule 18.3, Tacking the Zone. As P and S are approaching the finishing mark on opposite tacks, rule 18, Mark Room, does not apply because the boats are on opposite tacks on a beat to windward. But once P tacks, the boats are no longer on opposite tacks and rule 18 begins to apply (see rule 18.1, When Rule 18 applies). When P and S are approaching a port-hand windward mark on the opposite tack and P then passes head to wind within the zone at the mark and is fetching the mark, rule 18.3 requires P to not cause S to sail above close-hauled to avoid contact. P causes S to sail above close-hauled to avoid contact; therefore, she breaks rule 18.3

This Week's Question

Two boats, L (a leeward boat) and W (a windward boat), are approaching the left-hand end of the starting line, which is a 16-foot powerboat. When W is three lengths from the end of the line, L becomes overlapped on W to leeward from clear astern. There are six seconds to go before the starting signal. L slowly luffs and W keeps clear. As L reaches close-hauled, the starting signal is made. L is a boat length from the powerboat and will not clear it sailing close-hauled. She luffs to head to wind, shooting up and around the powerboat, and then bears away to a close-hauled course. W keeps clear throughout, and protests L for sailing above close-hauled after the starting signal. You are on the protest committee; which boat should be penalized? (From Perry, Quiz 25)

Answer

Boat W’s protest is disallowed. The 16-foot powerboat ranks as both a “mark” and an “obstruction” to the 18-foot sailboats (see the definitions Mark and Obstruction). The preamble to Section C, At Marks and Obstructions, states that the rules of Section C, which include rule 18, Mark-Room, and rule 19, Room to Pass an Obstruction, do not apply “at a starting mark surrounded by navigable water.” Therefore, the situation is governed by the rules of Sections A and B. L becomes overlapped to leeward from clear astern of W. Therefore, rule 17, On the Same Tack; Proper Course, requires her to not sail above her proper course. Before the starting signal L has no proper course (see the definition Proper Course); therefore, she is free to sail up to head to wind, provided that when she changes course she gives W room to keep clear (rule 16.1, Changing Course). After the starting signal, L is required to not sail above her proper course. In this case her “proper course” (the course she would sail to finish as soon as possible) is to luff head to wind, coast past the powerboat and then bear away to a close-hauled course (see the definition Proper Course). L sails no higher than this course, and therefore does not break rule 17; and while she is changing course, L gives W room to keep clear under rule 16 .1 as demonstrated by W’s performance. W correctly keeps clear under rule 11, On the Same Tack, Overlapped

This Week's Question

Blue and Yellow are sailing upwind. Blue tacks. During Blue’s tack, Yellow heads up to avoid Blue. There was no contact. Yellow alleges Blue broke Rule 13. Blue alleges she kept clear. Which boat(s) should promptly take a penalty?

Answer

Blue should take a penalty. Rule 13 requires Blue to keep clear of other boats until she is on a close-hauled course. The definition of keep clear states: Keep Clear. A boat keeps clear of a right-of-way boat: (a) if the right-of-way boat can sail her course with no need to take avoiding action and, (b) when the boats are overlapped, if the right-of-way boat can also change course in both directions without immediately making contact. Blue did not keep clear between the time she passed head to wind until she was on a close-hauled course. Yellow was forced to head up to avoid Blue.

This Week's Question

Red and Green are sailing upwind. Red asks permission to cross, and Green replies, “cross.” Green then ducks Red. A third boat, not involved in the situation, protests Red for not keeping clear of Green. Which boat(s) should promptly take a penalty?

Answer

Neither boat should take a penalty. Red should not be penalized, since she kept clear of Green. A boat is keeping clear if the right-of-way boat (Green) can sail her course. Her course implies the course of her choosing – it specifically does not say proper course. Sailing the course of her choice is accepted as normal behavior because starboard may choose to duck due to tactical considerations or for any reason of her choosing.

something we can discuss on the porch on Sunday.

This Week's Question

Boats P (on port tack) and S (on starboard tack) are beating to windward. P tacks into a position just in front of S. When P reaches a close-hauled course, she is a few feet clear ahead of S. S, who has not needed to change course prior to that moment to avoid P, immediately luffs above a close-hauled course, avoids contact and protests. You are on the protest committee: how do you decide this?

Answer

S’s protest is dismissed; neither boat breaks a rule. While P is on port tack she is required to keep clear of S by rule 10, On Opposite Tacks. While P is tacking, she is required to keep clear of S from the moment she passes head to wind until she reaches a close-hauled course by rule 13, While Tacking. A boat “keeps clear” if the right-of-way boat can sail her course with no need to take avoiding action (see the definition Keep Clear). S does not need to take any avoiding action before P reaches a close-hauled course. When P reaches a close-hauled course, rule 13 ceases to apply and P is the right-of-way boat under rule 12, On the Same Tack, Not Overlapped. Because she acquired the right of way by her actions, P is required to give S room to keep clear of her by rule 15, Acquiring Right of Way. S is able to avoid P in a seamanlike way; therefore P complies with rule 15.

This Week's Question

Blue and Yellow are approaching the leeward mark. Yellow does not give Blue room to round the mark. Blue keeps clear of Yellow. Which boat(s) should promptly take a penalty?

Answer

Yellow should take a penalty, since she broke Rule 18.2. Since Blue was overlapped with Yellow when Yellow reached the zone (Remember: overlap is taken from the transom... look carefully), Yellow was required to give mark-room to Blue.
