Seebold once said he could kick your butt on the water, share a beer with you afterwards and somehow leave you enjoying both experiences.
Seebold won more than 900 races and 69 world and national titles in a 46-year career. He retired after the 1997 season, in which he won the PROP Tour Formula One championship at the age of 57. Most of the drivers he beat that season were young enough to be his sons. Two of them were his sons.
Seebold was a fierce competitor with a sixth sense for putting his boat where few other drivers could put theirs, and for knowing where competitors were going to turn before they decided themselves.
But he left his aggressiveness on the water. On shore he was a modest, personable man who almost always had a smile on his face.
Seebold stayed in top form until his last race. "I always gauged my success by the fear of the other drivers," he said. "I figured I was still competitive if they were more afraid of me than I was of them."
