Catherine’s eyes were shielded by a glamorous pair of oversized sunglasses while her raven-black locks were tied up in a low bun.

Meanwhile, Michael kept it casual in burgundy board shorts, which he wore with a slate gray T-shirt.

The award-winning actor completed his look with a black baseball cap and clear-rimmed sunglasses.

The duo was joined by a host of friends aboard the yacht, enjoying a buffet lunch and sharing many tender moments.

The Fatal Attraction star has been married to Wednesday actress Catherine Zeta-Jones, who is 25 years his junior, since 2000.

The pair tied the knot at the Plaza Hotel in NYC after they began dating two years earlier and have become one of Hollywood’s most enduring couples.

In 2001, Catherine told Larry King how their relationship began: “We met in 1996 at the Deauville Film Festival…I think it was 1996!”

“I was told Michael Douglas wanted to meet me. I was a little nervous because I wasn’t sure what he wanted to meet me about.’

Douglas promoted A Perfect Murder and Zeta-Jones promoted The Mask of Zorro.

Their friends Antonio Banderas and Melanie Griffith – who used to be married – introduced the actors at a private dinner.

Michael asked Catherine if he could sit next to her.

He famously told her he was going to be the father of her children, which shocked her, and soon after sent flowers to apologize. They started a friendship.

“Nine months later, I still have long conversations with him on the phone, great dinner dates, and I’m constantly wondering, ‘Why aren’t we together?'” she told King.

“We looked at each other one day and said, ‘We’re having a lot of fun together,'” she said.

Michael proposed on New Year’s Eve in 1999 at his home in Aspen with a $1 million diamond ring.

“We were both sick to death because we had (the) flu,” the actor told ITV’s Ross King in 2016.

Catherine and Michael together have son Dylan, 22, and daughter Carys, 20. Michael also has son Cameron Douglas, 43, from his first marriage to Diandra Luker.
