Debbie Cavanaugh, who coaches Fort Lauderdale High’s boys and girls swimming and diving, and water polo, teams, met her husband at a competitive swimming meet more than a quarter-century ago. While their marriage has been steady since they tied the knot in 1989, they haven’t stopped making waves in the pool.

Debbie Cavanaugh, 55, and her husband, Cav Cavanaugh, 77, are among the competitors in this year’s YMCA Masters National Swimming Championship, which will be held Thursday through Sunday at the Fort Lauderdale Aquatic Center.

Together, they’re scheduled to participate in 12 events combined. Debbie Cavanaugh said she’s signed up for the 50, 100 and 200-meter backstroke and the 50, 100 and 200 breastroke, as well as the 400 freestyle relay, in which she and her three teammates hope to set a national record.

Cav Cavanaugh is the world-record holder in the 100 freestyle (1:05.04) in the 70-74 age group, Debbie Cavanaugh said. A former swimming coach himself, he plans to compete in the 50, 100 and 200 free, the 50 butterfly and the 100 individual medley.

The two will be representing the Broward County YMCA.

“People are amazed,” she said of their many years swimming competitively together. “We’re sort of attached at the hip, is how I like to look at it. We enjoy our swimming and we enjoy each other. It’s something we’ve done together, and everything flows easy for us.”

Just how well do they get along? Well, Debbie Cavanaugh said, they sailed the Carribean for five years (1990-95) together alone aboard an Irwin 37 sailboat.
