The 2019 Rolex Sydney Hobart has been conducted in benign conditions and has been free of the controversy that has often dogged the race in recent years.
It has taken until the third day for the protest to be lodged.
Quest lodged a protest against Envy Scooters, alleging that Envy Scooters failed to give way in a port-starboard incident at the Victory mark as the fleet left Sydney Harbour.
Both boats finished last night and the protest was heard at 3pm today at the Royal Yacht Club of Tasmania.
After long deliberation, the International Jury found that Envy Scooters, on port, had failed to give way to Quest, which was on starboard, and that caused Quest to take evasive action.
Envy Scooters was hit with a 2 hour time penalty which will be added to her finish time.
Only three boats have retired from the race. Hollywood Boulevard broke her rudder at the start and retired to the CYCA. Faster Forward had steering problems on the first day and retired to Wollongong and Minerva also retired and went to Eden.
