GSC offers inshore, offshore and twilight racing competition.
Inshore racing is held on Sunday afternoons on Brisbane Water throughout summer from September to April. Competition is based on a handicap system to allow all different boats an opportunity to win.

Offshore racing involves mixed yacht racing in waters between Terrigal and Sydney Harbour. Competition can be held over either 1 or 2 days with racing to and from Sydney Harbour. 

Twilight Racing runs from 5:30pm during daylight saving on Brisbane Water.
Starts and finishes are in front of the club around fixed courses.
