Mark-Room — Clear Ahead at the Zone
When a boat is clear ahead as she reaches the zone, the boat clear astern must give her mark-room — a late dive inside earns nothing.
Mark-room isn't only for an inside overlap. If the boats are not overlapped when the first of them reaches the zone, the boat that hasn't reached the zone — here the one clear astern — must give the other mark-room (rule 18.2(a)(2)). The trailing boat can't manufacture an inside overlap inside the zone and demand room; the leader is entitled to round, and the chaser keeps clear and rounds behind.

- Rule 18.2 — Mark-Room — Overlap Too Late · see also
An overlap obtained only after the zone gives the trailing boat no mark-room.
