A missing-person search for Halit Yukay, owner and lead designer of Mazu Yachts, is still underway as authorities locate the wreckage of his yacht, Graywolf, off the coast of Marmara Island in Balikesir, Türkiye. The 43-year-old had reportedly set sail from Yalova to the Greek island of Mykonos.

Founded in 2011 by Yukay in Yalova, Türkiye, Mazu Yachts builds carbon-composite and steel-hulled yachts with composite superstructures ranging from 11 to 40 metres. Yukay began designing boats as a child, completing his first major project, a 16-metre yacht, before launching the company. 

On 4 August at 23:40, relatives of Yukay reported him missing after losing contact. He had departed Yalova Setur Marina at 15:10 the same day on his privately owned Turkish-flagged yacht. He is believed to have been alone at the time.

At around 14:30 the following day (5 August), a commercial vessel navigating off the coast of Turanköy, Kapıdağ Peninsula, observed partially submerged boat debris at sea. Coastguard vessels were dispatched to the location.

Once at the scene, the teams searched the semi-submerged vessel with a dive team to locate Yukay; however, no evidence has been found so far. Search and rescue operations have continued since, using one helicopter, one dive team and seven Coastguard vessels.

An investigation into the incident is currently underway. Underwater footage revealed deep cracks in the yacht’s hull, believed to be the result of an accident. Both diving teams and aerial search units are continuing their efforts to find the missing businessman.
