Martha Nolan-O’Slattara Found Dead on Yacht at Luxury Montauk Resort: Mystery Surrounds Fashion Designer’s Death

Fashion designer and entrepreneur Martha Nolan-O’Slattara, 33, was found dead on Tuesday morning, August 5, 2025, aboard a yacht docked at the Montauk Yacht Club, a luxury resort in the Hamptons, New York. Emergency responders attempted CPR, but she was tragically pronounced dead at the scene.

The exact cause and manner of her death remain unknown, with authorities ruling it inconclusive, according to The East Hampton Star. Law enforcement, including homicide detectives, are currently investigating. Witnesses and nearby boaters reportedly heard screams coming from the docks around the time her body was discovered, as per The New York Post and The Mail.

Originally from Ireland, Martha Nolan-O’Slattara was the founder of the fashion label East x East, which has been active in New York for nearly four years. She also launched Duper, another fashion venture, and served as the CEO of Brand Growth Consultants. Most recently, she held the role of Director of Operations at K4 Capital Management since June 2024.

Just weeks before her passing, Martha shared a TikTok post celebrating the opening of her East x East pop-up store in Montauk, captioned “Goals Achieved.” The video showcased racks of stylish beachwear and swimwear—her final post on social media.

Her accounts were filled with glamorous lifestyle content, including her travels to Saint Barts and clips of scenic flights over New York City. In one post, she wrote, “New York or nowhere.”

The Montauk Yacht Club, where she was found, is a high-end resort known for its private beaches, lakefront views, luxury dining, and summer rates reaching $1,500 per night. The property is home to Montauk’s only padel courts and caters to elite guests during peak seasons.

The sudden and unexplained death of Martha Nolan-O’Slattara has left friends, fans, and the fashion industry in shock. Investigators are expected to release more details as the case unfolds.
