RULE 30
U / Z / Black Flag — the Triangle
In the last minute under a Z, U or black flag, a boat on the course side inside the start triangle is penalised — 20%, DSQ, or DSQ even after a recall.
Under the Z flag (rule 30.2), U flag (rule 30.3) or black flag (rule 30.4), a boat in the triangle formed by the ends of the starting line and the first mark during the last minute before her starting signal is penalised: a 20% scoring penalty (Z), disqualification that a restart wipes (U), or disqualification a restart does NOT wipe (black). Time the line so you're behind it at the gun.
