Everyone can place a bid until 21 September 2026.What makes this WSM houseboat so suitable as a floating home?She combines residential comfort with the practical amenities you would expect from a luxury houseboat. On board you will find, among other things, a shower, hot water, refrigerator, freezer, oven and cooking facilities, making longer stays an obvious choice. With four permanent berths, the layout is attractive for a family, a couple who enjoys hosting guests or anyone looking for a representative place to stay on the water. The central heating system contributes to a pleasant interior climate across several seasons. The large freshwater tank of approximately 1,800 litres and the black water tank of approximately 1,000 litres also support the concept of comfortable, longer-term self-sufficient living, while the toilet waste is not discharged directly into open water—an important consideration for many buyers of a houseboat or residential vessel.How does she handle, and what can you expect from the engine?This WSM houseboat is equipped with a 240 hp Iveco inboard diesel engine, a six-cylinder engine from 2021 with approximately 100 operating hours. This makes her interesting for anyone looking for a powerful propulsion system suited to the boat’s size and weight, which is approximately 80,000 kg. The cruising speed is around 9 km/h and the maximum speed approximately 15 km/h, making her well suited to comfortable cruising on inland waterways. She is operated from inside via a joystick, which makes manoeuvring intuitive, especially in combination with the electric bow thruster. Instruments such as the oil-pressure gauge and temperature gauge provide the necessary information while cruising. For added convenience, there is an electric anchor winch with chain and one anchor, reducing the amount of manual work required when mooring and anchoring.What about the power supply and onboard autonomy?Anyone searching for terms such as autonomous houseboat, off-grid houseboat or self-sufficient residential boat will recognise the appeal of this vessel’s equipment. She has shore power, an alternator, a battery charger and solar panels, supplemented by a Fischer Panda generator (model 15000) with a capacity of 15,000. With 24 batteries on board and multiple voltage levels (220V, 24V and 48V), the electrical system is designed for comfortable use of onboard equipment. This makes her attractive for longer voyages or stays in locations where you do not want to remain continuously connected to shore power. The combination of solar energy, generator and shore power offers flexibility, whether you are planning a weekend away or want to live on the water for a longer period.What navigation equipment and amenities are available for inland waterways?For safe and relaxed cruising, she is equipped with AIS, an autopilot, depth sounder, GPS, chartplotter, compass and VHF radio. This is a complete navigation package for rivers and lakes, and ideal for anyone who enjoys longer journeys. Outside, you will find features including a teak deck, swimming platform and swimming ladder, making time on board especially inviting on warm days. Covers are available to protect or cover parts of the deck when the boat is not in use. An electric bilge pump is also fitted on board.What documentation is available with this lot?Extensive documentation is available with the boat, including planning documents, manufacturing drawings, construction documentation and photographs. The Union certificate and ship’s certificate are also included. This is valuable for buyers who would like insight into the construction, technical systems and history of the project. The boat is registered in the Hamburg Ship Register. According to the information provided, she was last taken out of the water for maintenance in 2025, and the antifouling treatment was also carried out in 2025.This WSM houseboat is therefore an interesting choice for anyone looking for an aluminium houseboat with residential comfort, powerful engine performance, joystick steering and an energy concept focused on self-sufficiency.
