NYC designer Martha Nolan-O’Slatarra finalized a divorce months before untimely death on Montauk boat

NYC designer Martha Nolan-O’Slatarra was found dead on a Montauk boat just months after finalizing a divorce from her husband, according to court documents.

The 33-year-old Irish-born beauty was in the middle of uncontested, or mutually agreed-upon, divorce proceedings with her husband Sam Ryan as recently as April, according to New York County Supreme Court filings.

The filings indicate the couple’s marriage ended just months before Nolan-O’Slatarra was found dead on a boat docked at the upscale Montauk Yacht Club around midnight last Tuesday — with a naked man seen belligerently begging bystanders to help her.

In another recent legal bout, Nolan and Dylan Grace, who co-owned East x East swimwear together, were sued in 2022 by Out East Accessories, a Manhattan luxury eyeglass outlet, according to a lawsuit.

The pair was accused of stealing $34,000 from a company bank account, as well as the entire eyewear inventory, the complaint alleged.

The suit also claimed the duo locked the owners out of their bank account, emails and social media accounts by changing the password.

The lawsuit was resolved as the sides settled in July 2022, according to court records.

Cops said there was no evidence of violence done to Nolan-O’Slatarra’s body, but have not ruled out foul play and have not released details of the department’s investigation.

The chaos unfolded around midnight, when two bystanders were awakened by screaming and saw the alleged owner of the Ripple boat, dashing down the dock in a panic.

“We were sound asleep,” the eyewitness, who asked not to be identified, told The Post.

“We heard someone shouting, stuff bouncing off the side of the boat. He threw sunscreen at our boat trying to wake us up,” he said. “He was running up and down, naked, screaming, ‘Do something!’”

Suffolk County police said the bystanders tried to resuscitate the popular designer before first responders arrived — but it was too late and Nolan-O’Slatarra was pronounced dead.

The 911 caller and his pal, regulars at the yacht club, did not recognize Nolan-O’Slatarra.

The blue-eyed beauty hailed from the small town of Carlow, just over 50 miles outside Dublin, she said in an interview last year with the Irish Independent.

Studious and driven to succeed, she earned a bachelor’s degree in business administration and management from University College in Dublin and went on to earn a master’s degree in digital marketing at the UCD Michael Smurfit Graduate School of Business, also in Dublin, in 2014.

“I always knew I wanted to be successful, that I was money-driven, business-driven, and that fashion is a tough industry and it would be a slow road,” she told the Independent.

At just 26, she was vice president of client experiences for an Irish-based retail marketing agency — and bored with her career, she told the outlet.

In 2021, she launched East x East and a fashion accessories company, Duper. 

The companies’ success was enough to allow Nolan-O’Slatarra to spend her summers in the Hamptons, where she was able to mix business with pleasure.
