Eighth Mulder ThirtySix new-build sold and named Castlefinn

12 May 2025 • Written by Dea Jusufi and Emily Dawkins

Mulder Shipyard has announced the sale of the eighth hull in its ThirtySix series, now christened Castlefinn

The 36-metre motor yacht was first launched in March this year and will remain at the Dutch shipyard for the next eight weeks to undergo further customisation works for her experienced Canadian owners.

According to the yard, she will depart the Zoeterwoude facilities in South Holland later this summer to complete her maiden voyage and first transatlantic crossing.

As an evolution of previous sisterships such as Seaflower and Solemates, the semi-custom yacht offers "more flexibility [...] whilst still maintaining the all-important Mulder DNA," according to the shipyard. The exterior design was headed up by Claydon Reeves Design Studio, while naval architecture is owed to Van Oossanen Naval Architects.

Her interiors –  which were first unveiled at the Palm Beach International Boat Show 2024 – are owed to "visionary" interior architect Roelfien Vos, who also designed the interiors of Mulder Shipyard's one-off, "anniversary edition" yacht.

Accommodation is for up to 10 guests and comprises a full-beam master suite, two VIP cabins and two convertible cabins. There is further space for six crew.

The model benefits from a renewed foredeck where owners can enjoy ocean views from a private lounge area complete with a U-shaped sofa and sunbeds. Further highlights include a seven-person spa pool, a dedicated gym and ample storage, including space for a Williams 625 tender and two water scooters.

Powered by twin Caterpillar 1,150hp engines, the Mulder ThirtySix is expected to reach a maximum speed of 17 knots and a cruising speed of 15 knots. She also complies with the latest environmental regulations.

The Dutch shipyard also revealed that construction on hull nine in the ThirtySix series is on track for launch and delivery in April 2026.
