Driven, maintained, traceable - this Neptunus 129 AK Fly is not a standing boat, but one with substance. 820 engine hours on two Volvo Penta TAMD 61A, built in 1992, one previous owner and documented modernizations: a setup that is rarely found in this class.

The Neptunus shipyard stands for solid, seaworthy motor yachts - and this is reflected here in the semi-planing hull and the well thought-out design. Two helm stations, hydraulic steering and bow thruster give you control both in port and on the water. The flybridge extends your radius of action: overview when underway, protection when needed, openness in good weather.

Below deck, the boat is consistently designed for longer stays: two cabins, two heads with electric toilets, galley with gas and electric hob and a saloon with round seating area and inside steering position. Standing height of 2 meters throughout ensures that you don't have to restrict yourself on board.

The drive provides the right basis for range and reliability: two Volvo Penta TAMD 61A engines with 306 hp each, known for their robustness and good accessibility in the engine room. With 1,300 liters of diesel, even longer trips can be realistically planned. Navigation and comfort are fully covered: radar, autopilot, GPS plotter and Eberspächer diesel heating. Important components such as batteries, cooling system and electrics have been renewed - certificates are available.

In short: a classic flybridge yacht with a clear history and solid long-distance technology - for all those who want to combine the classic flair of a Dutch shipyard yacht with real utility value.

The most important facts: 13.8 m × 4.2 m × 1.15 m | Year of construction 1992 | 2 × Volvo Penta TAMD 61A, 612 hp diesel | 820 engine hours | Condition: good, well-maintained | 1 previous owner | Location: Brandenburg an der Havel
