Blue infringes rule 24.1
and rule 10 and will
therefore be penalized. It is immaterial whether Red loses a place or not. Red
is still racing
because she has not yet cleared the finishing line. Blue has cleared
the finishing line and is thus no longer racing.
She can thus no longer be penalized for breaking rule
10 but Blue will be penalized under rule
24.1 because she has interfered with a boat that was still racing.
Moreover, Blue cannot do a two-turns-penalty
to correct her rules infringement because she is no longer racing!
