The ninth unit in the Mulder ThirtySix yacht series has now embarked on sea trials in the North Sea following her departure from the Dutch yard's facilities in Zoeterwoude-Rijndijk this weekend (9 May).
The 36-metre superyacht hit the water in March, though she first appeared outside the dock last week, revealing her light grey hull, red and white bootstripe and the taut, slender lines of the model. Her sale – closed in a deal with broker Alex Lees-Buckley of Camper & Nicholsons – was announced in September 2025, with the yacht built for experienced owners with a passion for long-range cruising and "refined" onboard living. Her delivery is scheduled for this spring.
The ThirtySix series began in 2017 with the delivery of Delta One, and has received much acclaim since, including at the 2018 and 2024 World Superyacht Awards. Following her spring delivery, the ninth unit will join sisterships Seaflower and Castlefinn on the water. Her strong, low-profile exterior design is by Claydon Reeves Design Studio.
The Dutch yard has taken the generous open flybridge from Seaflower for this latest unit – a feature well noted by the 2024 World Superyacht Awards judges – as well as a new Seakeeper 40 gyro to complement the model's electric stabiliser fins.

Interiors will be by long-standing collaborator Vickers Studio and reflect a bespoke "balance of elegance, comfort and functionality", with further details undisclosed. However, her four-cabin layout will include a distinct second master suite on the lower deck for a more private option.
The ThirtySix model will also come with Van Oossanen's patented Fast Displacement Hull Form (FDHF), which ensures smooth sailing, fuel efficiency and stability up to her maximum speed of 17 knots.
The news follows the sale of Delta One, Mana I (now Josephine), and the eighth unit, Castlefinn, last year.
