Race Staring Sequence
1. During both qualifying and eliminations the following sequence will occur:
Course Is Closed – Solid Red Lights Are On
Get Ready Warning – Amber Lights Start Flashing
Get Set Warning – After ambers have flashed for 20 seconds, they will go solid for 5 seconds. (This is a 5 second warning to the drivers that the 9 second countdown will begin.)
START THEIR PASS – After the 9 second count, the amber lights goes out and the green light comes on.
2. The starting line objective is for the boat(s) to have left the holding rope area and be at the starting line when the countdown is completed and the light turns green. Should a boat cross the starting line before the green light is lit, a red light will be automatically activated signifying a "red-light" (foul start).
3. If a boat fouls or breaks out of an index class during eliminations, it is out of the program, unless its competition has failed to fire or is disqualified, the competition must cross the start line under engine power within 5 seconds of the lead boat in order to win the round.
