The APBA Gold Cup unlimited hydroplane race will be in August in 2015, the Detroit River Regatta Association said Saturday. Racing is scheduled for Aug. 21-23 on the Detroit River, although a three-day show is not certain, race director Mark Weber said.
One reason for the change was to get the Gold Cup away from the July 4 holiday.
"When the third weekend in August opened up, we jumped at the chance," Tom Bertolini, president of the DRRA, which produces the race, said.
The Grand Prix racing class will be part of the 2015 Gold Cup, Bertolini said. They will compete for the Silver Cup.
Sam Cole, chairman of H1 Unlimited, said his organization supports the date change.
"Our priority," Cole said, "is to ensure that the move benefits fans, sponsors and our teams in a manner that provides a positive impact on our series. H1 is committed to assisting the DRRA and help ensure the long term viability of the Detroit event and the APBA Gold Cup race."

Jimmy Shane edged J Michael Kelley by less than one boat length to win the Air National Guard H1 Unlimited Series hydroplane racing event at Tri-Cities, Wash., on Sunday.
Dave Villwock, the Detroit Gold Cup champion, finished third in the first ANG event since the race on the Detroit River.
Shane, of Havre de Grace, Maryland, who drives the U-5 Graham Trucking, called the victory, "the fulfillment of a childhood dream."
