Rule 10 On Opposite Tacks
Rule 18.1 When Rule 18 Applies
Rule 18.2 Giving Mark-Room

Question

Boats Y on port tack and B on starboard are sailing parallel courses on a run and
are approaching a starboard-hand leeward mark. Y is clear ahead when she
reaches the zone. Y slows and B becomes overlapped outside her. Y now sails
past the mark and luffs slightly. B has to change course and protests. What
should the call be?

B1

Y1
B2

Y2
B3

Y3
B4

Y4

Answer

Penalize Y.

When Y reaches the zone, she is on port tack and must keep clear. However, she
is entitled to mark-room under rule 18.2(b).

At position 2, Y is sailing her course to the mark and the obligation on B to give
her mark-room remains.

After position 3, Y is no longer sailing to the mark, nor is she rounding it. Y
must keep clear under rule 10, and by causing B to change course Y fails to keep
clear.
