Topic: Proper Course Posted: 15 Nov 15 at 11:59am |

On a run Position 1. Blue is clear ahead, RoW. Yellow is clear astern. Yellow must keep clear (RRS 12). Blue must give yellow room to keep clear when she changes course (RRS 16.1). (*) (Both should avoid contact - RRS 14). Position 2. Blue is overlapped to windward of Yellow. Blue, as a windward boat, must keep clear of Yellow (RRS 11). Yellow has acquired RoW by becoming overlapped to leeward of blue. She must therefore initially give Blue room to keep clear. (RRS15) When yellow changes course, she must give blue room to keep clear (RRS16.1). (*) Yellow has become overlapped to leeward of blue within 2 of her hull lengths. She should therefore not sail above her proper course while they remain on the same tack and overlapped within that distance, unless in doing so she promptly sails astern of blue. (Both boats should avoid contact). Proper course is defined as "Proper Course A course a boat would sail to finish as soon as possible in the absence of the other boats referred to in the rule using the term. A boat has no proper course before her starting signal." *( No course changes in this scenario to bring 16.1 into action). On a reach All the same points as above apply. So again, yellow should not sail higher than her proper course while she's overlapped with blue (unless she sails astern). Note, however, that Yellow's proper course in this scenario does not include luffing as a result of blue's wind shadow (the other boat referred to in the rule (17)).

What's wrong with it is that, in its 'nautical use' demonstrated by numerous posters in rules threads, the verb 'to luff' has a multiplicity of meanings with various qualifications, such as a change of course:
Notwithstanding your content analysis of various sources, I would point out that the racing rules applicable to fleet racing only use the word 'luff' as a noun meaning a part of a sail. I remain convinced that rules discussions would be better off without using the term.

Further, right of way rules operate independently of rule 17. As long as there was room for W to keep clear, whether or not L broke rule 17 does not affect whether W kept clear, and L, if she broke rule 17, cannot be said to have compelled W to break rule 11 as a consequence of L breaking rule 17, so W cannot be exonerated for breaking rule 11 under rule 64.1( a ). |

On a reach the proper course for almost all boats is a straight line to the next mark. [/QUOTE]
On windy reaches, even in a una rig single hander, you may have to head up in the lulls so as to be able to bear off to avoid being overpowered in the gusts. |

Definitely not true. I can assure that the boat that gets the gust first will usually get to the next mark first. this will involve changing course to meet it and then changing course once they are in it.
