DMS Holland's All-in-One fin stabilisation system has made its first Dutch new-build installation aboard a Van den Hoven Voyager 50 Coupé. The 50-foot motor yacht uses the system to reduce roll while under way and at anchor, giving the installation direct relevance to the owner-operated luxury-yacht market.

Van den Hoven was the launch customer for the system and has now moved from development work into a completed production-yacht installation. DMS says the All-in-One is currently available for yachts from 45 to 65 feet.

One fin system covers three operating modes

The All-in-One is designed to stabilise at zero speed, conventional cruising speeds and higher planing speeds. At anchor the fins use a flapping movement, while at cruising speed they rotate in a more conventional stabiliser mode.

At higher speeds the fins fold behind the transom and are used for trim and motion control. Combining those modes in one system is intended to avoid the compromises that can arise when separate devices are installed for different operating conditions.

The Voyager 50 is the first Dutch new build

DMS says the Voyager 50 installation is the first new yacht built in the Netherlands with the complete All-in-One package. Van den Hoven selected the system for a model aimed at a younger audience while retaining the comfort expected from the yard's cruising yachts.

The 50-foot size is important because stabilisation has increasingly moved from large crewed yachts into owner-operated boats. Buyers now expect meaningful motion reduction without accepting machinery that consumes excessive interior volume.

Reduced drag is part of the design objective

DMS states that its high-aspect fins require less deflection to produce a given stabilising force than a conventional single-axis fin. The company claims this can reduce drag during underway stabilisation while maintaining strong zero-speed output.

Real-world performance will depend on hull shape, displacement, speed and installation geometry. The Voyager 50 provides a useful production platform on which owners and builders can judge those claims under normal cruising conditions.

Comfort technology continues moving down in size

Stabilisers were once treated as specialist equipment for much larger yachts, but they are becoming common on boats around 15 metres. Systems that can work at anchor and under way are particularly attractive because they influence comfort throughout the ownership cycle rather than only during passages.

For LYG buyers, the Voyager 50 installation shows that sophisticated motion control is no longer confined to superyachts. It is becoming part of the specification discussion on mainstream luxury motor yachts below 24 metres.
