Red and Blue are overlapped on the same tack, with Red being the inside boat
as the boats reach the zone. Rule
18.2(b) and rule 11
thus apply. Blue has to keep
clear and give mark-room.
Red's luffing as shown in the film does not change this situation. Red sails
her proper
course and an infringement of rule
16.1 is exonerated by rule
21.
