Rules Quiz
Keeping Clear and Avoiding a Collision
Situation
Green (on starboard) and Red (on Port) were
approaching each other in a crossing situation. When the
boats were approximately three boatlengths apart, Green
hailed “Starboard”. At two boatlengths, Red started to
bear off to pass astern of Green but Green started to bear
Green
off at the same time. Seeing this, Red continued to bear
off but so did Green. As Green passed to windward of
Red
Red, her sails blanketed Red’s sails resulting in contact
between the rigs and serious damage to Red’s mast.
Green protested Red under RRS 10.
Red protested Green under RRS 16.
Conclusions and Rules that Apply
RRS 10 requires Red to “keep clear “of Green and
RRS 16 requires Green to give Red room to “keep clear”.
Red would have kept clear of Green if Green had not
borne off and then continued to bear off further. By doing
this, Green did not give Red “room” to “keep clear” and
therefore broke RRS 16.1.
Green
In addition, since her maneuver brought about a
collision with damage, Green also broke RRS 14 (b) and
is disqualifi ed under both rules.
Despite her efforts, Red failed to “keep clear” of
Red
Green and therefore broke RRS 10 however, she is
exonerated under RRS 64.1 (b) and Green’s protest is
disallowed.
