Question
Yellow and Blue are sailing in one match and Red and Green in another. Green
meets Yellow on the course and Green is the right-of-way boat. Is it permissible
for Green to change her course so that Yellow has no need to change course to
keep clear?
Answer
Yes, provided that the change of course by Green is 'consistent with complying
with a rule and winning her own match.'
If Green clearly disadvantaged herself by her course change, then she would
have broken rule C2.9.
