Apex Concept Now Available in a 50-Metre Sub-499 GT Configuration

August 14 2026 | News release

Following the earlier presentation of the 60-metre Apex Concept, Studio Mulder Design is pleased to announce that the design is now also available as a 50-metre variant. In this configuration the yacht remains below 499 GT — a deliberate design choice that combines the presence and capability of a full-custom motor yacht with the operational advantages of a sub-500 GT vessel.

Engineered to Deliver Efficient Performance

As with the 60-metre platform, both the naval architecture and exterior styling of the 50-metre Apex Concept have been developed entirely in-house by the Dutch design studio. The aluminium hull and superstructure measure 50.00 metres in length, with a beam of 9.60 metres and a draught of 2.30 metres. Accommodation is provided for 10 guests and 10 crew, while the interior may be tailored entirely to the owner’s wishes.

The 50-metre variant retains the performance-oriented character of the original brief. Twin MTU 20V4000M93L main engines deliver a combined output of 8,600 kW (11,532 hp). In the lighter, more compact hull this translates into a top speed of 33 knots at light load — a notable step up from the 60-metre platform — while a cruising speed of 10 knots provides a transatlantic-capable range of 3,500 nautical miles.

Designed as a True Global Explorer

By staying under 499 GT, the 50-metre Apex Concept offers meaningful benefits in terms of manning requirements, regulatory scope and overall operating costs, without compromising on volume, comfort or design ambition. It positions the yacht as an efficient and highly capable option for owners seeking a strong balance between performance, range and ease of operation.
