No she can't once one of them is in the zone.

She can if:
  1. neither boat has reached the zone, AND
  2. she did not become overlapped within two of her hull lengths to leeward from clear astern, and is thus required  by rule 17 to not sail above her proper course.

If overlapped at the zone, inside has mark room which includes room to tack.

The overlap was established well outside the zone

Rule 11 applies throughout as they are overlapped so W must keep clear of L. However, W is entitled to 'mark room' as soon as the closest boat enters the zone (18.2b). 

W loses the entitlement to mark room once she passes head to wind as this switches off when the boat entitled to room tacks Rules 18.2c. So if W was not fetching the mark they may be vulnerable to another boat getting an overlap

In reality the loss of mark room for W when they tack is immaterial as it is likely that L will be clear astern after both boats have tacked so must keep clear.

Sounds like straightforward RRS 18 to me.
18.2 ( b ) If boats are overlapped when the first of them reaches the zone, the outside boat at that moment shall thereafter give the inside boat mark-room. If a boat is clear ahead when she reaches the zone, the boat clear astern at that moment shall thereafter give her mark-room.


There's a slight complication when they tack for the mark, but its not normally significant.

With Jim on this one, the inside overlapped boat is entitled to mark room as long as the overlap was established in line with the caveats of rule 18.

Which boat is the inside one? When was the overlap established?
This sounds like a straightforward mark room situation. If a boat is entitled to mark room they can't be pushed out. If not...
