Racing Rules Difficult 01-10

Multiple Choice

1. Which boat will be penalized in a valid protest?

• Red

• Blue

• Red & Blue

Red and Blue will be penalized. Blue can fetch the finishing mark. Because of rule 20.1(c) Red shall not hail for room to tack. In doing so she infringes rule 20.1(c). If Red hails for room rule 20.2(b,c) requires Blue to respond either by tacking or by immediately replying "you tack" and then giving room. Blue fails to do this. The finishing vessel also is a mark and Red is entitled for mark-room by rule 18.2(b), but mark-room in this case does not include the room to tack. Therefore Red will be penalized for infringing rule 13 and rule 20.1(c) and Blue will be penalized for infringing rule 20.2(b,c).

4. How is the rules situation between Red and Blue?

• Red shall keep clear, Blue has no obligations

• Blue shall not interfere, Red has no obligations

• Red shall keep clear and Blue shall not interfere with Red

Rule 11 applies and Red shall keep clear. Blue is sailing this course only to keep clear of Green and therefore is sailing a proper course and does not infringe rule 23.2. Blue is also required by Rule 15 to give Red initially room to keep clear.

5. Is Red allowed to hail for room to tack?

• Yes

• No

Yes. Safety requires Red to make a substantial course change to avoid Green that ranks as obstruction. Therefore Red is entitled by rule 20.1 to hail for room to tack. Green is not a mark, therefore rule 20.1 (last sentence) is not applicable. When it became clear that Blue was not giving room by tacking than Red should keep clear by passing astern of Green and protest.

• Yes

• No

Yes. Blue passes head to wind from port to starboard tack in the zone. Therefore rule 18.3 applies and Blue must give mark-room to Red that has been on starboard tack since entering the zone if Red becomes overlapped inside Blue. If Red infringes rule 15 she will be exonerated by rule 43(b).
