Shutting the Door at the Pin
At a pin-end start, the leeward boat can luff to hold windward boats out of the pin — windward keeps clear, with no proper-course limit before the start.
Before the starting signal there is no proper course, so a leeward boat is not limited by rule 17 and may luff a windward boat up to head to wind. The windward boat must keep clear under rule 11. The pin is a starting mark, so rule 18 is switched off and no boat is owed room to squeeze between the leeward boat and the pin. The leeward boat must still give room to respond when she changes course (rule 16.1).

How it interacts with other rules
- Rule 16 — Changing Course · limited by
A luff is a course change — the leeward boat must give the windward boat room to keep clear.
- Rule 17 — On the Same Tack; Proper Course · see also
Rule 17's proper-course limit doesn't bite before the start — there is no proper course yet.
- Rule 18.1 — No Room to Barge at the Start · see also
The committee-boat-end version: rule 18 is off there too, so a windward boat can't barge in.
