Two days of racing will be packed into one full day of action when the world’s fastest race boats will compete in the 111th running of the APBA Gold Cup in Madison, Indiana, on Sunday.

The change in the schedule for the H1 Unlimited Racing Series event was caused because debris in the Ohio River forced the cancellation of most of Saturday’s schedule.

Heavy rains in the area earlier in the week caused the Ohio River to rise to the point on Friday that all racing activity had to be cancelled.

Although the weather was ideal in Madison on Saturday, the swollen river still carried a large amount of tree branches and other debris that present a hazard for boats that reach speeds of 200 miles per hour.

Water condition improved enough by late afternoon to allow several H1 Unlimited hydroplanes to finally venture onto the racecourse for testing.

Jimmy Shane of Covington, Washington, driving the Miss HomeStreet, a craft that is owned by the citizens of Madison, thrilled the hometown crowd with a lap of 151.6 miles per hour in one of those runs.

Dave Villwock of Monroe, Washington, the most successful driver in the sport’s history, turned in the day’s second-best lap of 150.7 miles per hour in Miss Beacon Plumbing.

With the postponement of Saturday’s schedule, Sunday will provide race fans with a full day of racing that will include three sets of preliminary heats and a final heat that will determine the next winner of the Gold Cup, the oldest trophy in motorsports.
