About Sirena Yachts

Premium production

Turkish motor-yacht brand of Sirena Marine, launched in 2016 — Germán Frers-designed semi-displacement cruisers from the 16-metre Sirena 48 (also as a coupé and a serial-hybrid coupé) through the 60, 68, 78 and 88 to the 36-metre Sirena 118, and the 42-metre steel Sirena Superyachts 42M.

Sirena Yachts says it implements benchmarks inspired by those of its parent company, Sirena Marine, draws on the resources of that company, and holds in high esteem the generations of Turkish boatbuilders before it. By the yard's account the brand was launched in late 2016 and debuted with the Sirena 64 at boot Düsseldorf in 2017, winning plaudits and orders. Within about three years it had sold its sixtieth yacht, with the Americas then its largest market, and in less than six years it delivered its hundredth, a Sirena 88 — by then the range was the 58, 68, 78 (launched at Cannes in 2022) and 88, with naval architecture by Germán Frers and interiors by designers such as Cor D. Rover, and the United States had taken more than half of all sales. A smaller entry model, the Sirena 48, followed in 2023, the year in which the yard delivered more than forty yachts. Growth led Sirena to lease waterside halls at Yalova near Istanbul, adding 150,000 square metres and bringing the workforce to about 1,200, to build its steel superyacht; the 155,000-square-metre main site inland builds the smaller series and a yard at Tuzla builds the 88 four at a time. The Sirena 118 was launched in 2026 ahead of its debut at the Cannes Yachting Festival, and the steel Sirena Superyachts 42M was due to launch in July 2026.
