When rule 20 applies, rules 18 and 19 do not.

  18. MARK-ROOM

     Mark-room for IS
       to sail to Mark, and
        to sail her PC while at M.

        boat's HULL enters Z.
     Live by this snapshot
        unless IS leaves the Z
          or one boat Tacks.
     Zone is 3 BL (typ) from M.
     Inside KC only gets R,
        including R to tack if OL.
     Outside KC must KC.

     Caution T w/i 2 BL at WM.
       T not cause F above CH,
       T not cause F to not pass
         M on the required side.

     Rule 18 is:
       n/a on OT at WM.
       n/a when one B,
         but not both, must T.
