Munster back rower Nick Williams scored a try on his debut for Dolphin as the Cork side easily accounted for Division Three outfit Ards at Musgrave Park.
George Finn, Williams, Gary O'Keeffe and Rory Kenneally each touched down as Dolphin turned around with a 25-6 half-time buffer.
Ards' only points of the game came from two Michael Lawton penalties, and while Dolphin had Barry O'Mahony and Williams sin-binned after the break, Kenneally and his fellow winger Paul Hurley shared out three more tries.
Scorers:
Dolphin: Tries: George Finn, Nick Williams, Gary O'Keeffe,
Rory Kenneally 2, Paul Hurley 2; Cons: Barry Keeshan 3; Pen: Barry Keeshan
Ards: Pens: Michael Lawton 2
