FIREFLY

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

The Mulder 94 Voyager sits within a Dutch shipbuilding tradition that treats weight, build quality, and long-term reliability as non-negotiable. The aluminium hull and superstructure are marine-grade throughout. The semi-displacement round-bilge hull form is what gives her the range figure: at 8.5 knots, twin CAT C18s burn 30 litres per hour combined across a 17,000-litre fuel capacity, enough for 5,000 nautical miles. That is what the hull and the engines do together at a practical cruising speed.

She sleeps eight guests in four ensuite cabins across a layout designed by Omega Architects and Vickers Studio. Interiors run real Zebrano wood flooring on the lower deck, oak tinted on the saloon level. The galley is all Miele. There are four large fridge-freezers, Starlink satellite internet, and a FLIR night vision camera for extended passages.

Firefly is the kind of boat that gets described by the people who build them as a Dutch superyacht in a compact package. At 28.65 metres she is solid, comfortable, and built to go.

At 8.5 knots, Firefly burns 30 litres per hour across both engines. With 17,000 litres of fuel on board, that gives her a range of 5,000 nautical miles, enough to cross the Atlantic without stopping. At her cruising speed of 11 knots the consumption rises to 90 litres per hour, still competitive for a 100-tonne vessel with this much interior space.

The semi-displacement round-bilge hull is what makes this possible. It is not a planing hull chasing top speed, it is a hull designed to move efficiently at sea for extended periods. Combined with Naiad zero-speed fin stabilisers, a FLIR night vision camera, Raymarine triple touchscreen navigation, and Starlink satellite internet, Firefly is equipped to cruise through the night comfortably and arrive in good order.

Top speed according to the captain is 14 knots. The boat is not built around it.

Firefly is the only Mulder 94 Voyager ever constructed. That matters because it means the hull, the layout, and the finish decisions were made once, for one owner, without compromise toward a production standard. The aluminium hull and superstructure are marine-grade throughout.

The teak deck, the solid cleats, the watertight bulkheads, the stainless steel anti-slip rings on the companionway stairs. These are details that reflect how the Dutch shipbuilding tradition approaches a working vessel.

Below decks, the same thinking carries through. Zebrano wood flooring on the lower level, oak tinted in the saloon, real wood throughout the guest areas. The master cabin runs full beam with a walk-in wardrobe, a separate vanity area, and an ensuite with bidet. The galley is Miele throughout: oven, induction hob, dishwasher, washing machine, dryer. There are four large fridge-freezers. The table in the saloon has a glass centre inset with certified real coral.

This is a boat built once, to a specific standard, and maintained by one owner since delivery.

Firefly is fully commercially coded and 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, a Bezenzoni passerelle, and 4,000 hours on each engine, all within normal operating range for a vessel of this type.

The crew quarters aft of the engine room accommodate four, with two twin cabins, a shared ensuite, a mess area, galley, and independent side deck access so crew movement does not intersect with guest areas. The layout is practical for a working charter boat.

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