Firefly is the only Mulder 94 Voyager ever built. A one-off of 28.65 metres in full-aluminium Dutch construction, she was designed from the ground up for long-range passage-making. One owner from new, currently in Malta, and fully commercially coded for charter.

Being a one-off matters. The hull, the layout and the finish were decided once, for one owner, with no compromise toward a production standard. She comes from a Dutch shipbuilding tradition that treats weight, build quality and long-term reliability as non-negotiable: marine-grade aluminium hull and superstructure, teak deck, solid cleats, watertight bulkheads, stainless steel anti-slip rings on the companionway stairs. The people who build boats like this describe her as a Dutch superyacht in a compact package. At 28.65 metres she is solid, comfortable and built to go.

The semi-displacement round-bilge hull is what gives her the range. At 8.5 knots, her twin CAT C18s burn 30 litres per hour combined. With 17,000 litres of fuel on board, that means 5,000 nautical miles, enough to cross the Atlantic without stopping. At her cruising speed of 11 knots, consumption rises to 90 litres per hour, still competitive for a 100-tonne vessel with this much interior space. This is not a planing hull chasing top speed. The captain puts her top speed at 14 knots, but the boat is not built around it. It is built to move efficiently at sea for long periods.

For extended passages she carries Naiad zero-speed fin stabilisers, a FLIR night vision camera, Raymarine triple touchscreen navigation and Starlink satellite internet, so she can cruise through the night comfortably and arrive in good order.

She sleeps eight guests in four ensuite cabins, in a layout designed by Omega Architects and Vickers Studio. Real Zebrano wood flooring runs through the lower deck, with tinted oak on the saloon level and real wood throughout the guest areas. The master cabin is full beam, with a walk-in wardrobe, a separate vanity area and an ensuite with bidet. The saloon table has a glass centre inset with certified real coral. The galley is all Miele: oven, induction hob, dishwasher, washing machine and dryer, alongside four large fridge-freezers.

The crew quarters aft of the engine room accommodate four, with two twin cabins, a shared ensuite, a mess area, a crew galley and independent side deck access, so crew movement never crosses guest areas. It is a practical layout for a working charter boat.

Firefly has an established charter history. She carries two 12-person SOLAS A life rafts, 21 life jackets, a fixed Novax fire suppression system, hydraulic bow and stern thrusters and a Besenzoni passerelle. Each engine has 4,000 hours, within normal operating range for a vessel of this type.

For a buyer who wants a vessel that earns while it is not in use, Firefly is ready. For a buyer who wants her private, the commercial coding brings the safety specification and operational discipline that go with it.
