First Mulder ThirtySix yacht Delta One completes extensive refit

11 August 2026 • Written by Emily Dawkins

Dutch builder Mulder Shipyard has announced the redelivery of the first unit from its ThirtySix series, Delta One, following a period of extensive refit works at the yard's facilities in Zoeterwoude-Rijndijk.

According to the yard, the 36-metre underwent "many months" of work with the Mulder 360° Service team, where "every technical system, every finish and every detail" was updated and refreshed for her owner. Details of the refit remain notably private, though the yard disclosed that Delta One was "part of daily life" at Mulder, with all works carried out by its craftsmen, engineers and in-house specialists. 

Her redelivery comes just over a year after the yacht changed hands to repeat Mulder clients in a deal overseen by Mulder’s Brokerage Department. 

Delta One was first delivered in 2017 as the flagship of the yard's fleet, built to a design by Claydon Reeves, who also developed the interiors alongside Vickers Studio, and naval architecture developed by Van Oossanen Naval Architects. She took home a Neptune at the 2018 World Superyacht Awards in her size category, praised for being a "well-balanced yacht" with an attractive masculine profile and features that, at the time, were more commonly associated with larger builds.

Features on board include accommodation for up to 10 guests, including a full-beam owner's suite forward on the main deck, a sizeable beach club at the stern and a large sundeck complete with an eight-person Jacuzzi.

Following her redelivery, the yacht has already embarked on her first charter period around the Balearic Islands in the Mediterranean, where she is expected to remain for the season. 

The ThirtySix model remains popular, with nine units already delivered and, according to BOATPro, the latest unit currently under construction. Mulder celebrated the delivery of the ninth unit, My Lady, last month.
