Specifications
Patrolboat 1500 (1973) 15-metre steel motor yacht with flybridge, twin Mercedes diesels and bow & stern thrusters
This 1973 Patrolboat 1500 is a characterful steel displacement vessel of approximately 15 metres, built for comfortable, controlled cruising on inland waterways, lakes, rivers and also coastal waters. With its distinctive appearance, generous outdoor spaces and practical layout, this motor yacht is of interest to buyers looking for a robust steel boat for longer trips, staying aboard, or potentially using the vessel commercially. The combination of two inboard Mercedes OM 652 marine diesels, a shallow draft of around 1.00 metre and additional manoeuvring aids also makes this vessel attractive for those who frequently navigate marinas, locks or tight berths.
Design, dimensions and handling of this displacement cruiser
With a beam of approximately 3.50 metres and an air draft of about 5.70 metres, the Patrolboat 1500 offers a balanced ratio between stability and accessibility across a wide range of cruising areas. The steel hull contributes to solid handling and the calm, steady tracking you would expect from a classic displacement boat. Cruising speed is around 14 km/h, with a top speed of approximately 18 km/h, making this motor yacht suitable for relaxed touring at a pleasant pace. Thanks to the relatively low fuel consumption (stated at around 6 litres) and the large diesel tank of approximately 1,100 litres, a substantial range is achievable, adding comfort for longer holiday cruises.
Engines and manoeuvring: twin Mercedes OM 652 and additional thrusters
Propulsion is provided by two Mercedes OM 652 six-cylinder diesel engines of approximately 135 hp each, electrically started and installed as inboard engines. Twin engines not only provide extra control in current or changing weather conditions, but also make docking and turning in confined spaces easier. In addition, this vessel is equipped with an electric bow thruster and, as stated by the owner, additionally installed bow and stern thrusters/jet thrusters for even more precision. In practice, this means you can position the boat calmly with small corrections, even when wind or current makes manoeuvring more challenging.
Steering and navigation: flybridge and interior helm with extensive electronics
A key advantage is the presence of a flybridge, giving you an elevated, unobstructed view over the vessel and surroundings in good weather. At the same time, there is an interior helm station set up for comfortable cruising in all seasons. On board you will find modern navigation and safety equipment such as AIS, radar, GPS, chartplotter, VHF radio, depth sounder, log/speedometer, compass and fishfinder. For additional visibility there are cameras at the bow and stern with two monitors, supplemented by (interior and exterior) security cameras. This makes cruising and docking more manageable, especially at night, in busy marinas or in reduced visibility.
On-board comfort: saloon, galley and sanitary facilities for longer stays
Inside, the vessel offers a headroom of approximately 1.85 metres and fixed berths for three people, fitting a motor yacht designed for multi-day trips. The saloon features a spacious seating area, complemented by a 42-inch television with automatic satellite system, a stereo system and a WiFi CampPro II for extended range in marinas or at moorings. For climate comfort there is a portable air conditioner, and heating is provided by diesel hot-air heating with two independently usable units, which is convenient in spring and autumn.
The galley is notably complete for this segment and includes practical liveaboard amenities such as a 4-burner gas hob, two refrigerators, a dishwasher, an air fryer and a new sink installation, supplemented by a coffee facility as stated. The sanitary system is equipped with a vacuum toilet that does not discharge directly into open water, and there is also a washing machine on board. With a freshwater tank of approximately 600 litres and a holding tank of around 400 litres, the vessel is suitable for longer stays without constant refilling or pumping out. Hot water can be supplied via the starboard engine or via a boiler in the forepeak, with taps providing both hot and cold water.
Power supply and exterior equipment: solar panels, inverter, tender and crane
The electrical system supports multiple voltages (12V, 24V, 48V and 220V), including a battery charger, alternator, inverter and voltmeter. There are six batteries on board, divided between starting and domestic use, plus a solar setup of four panels (total approx. 960 watts) contributing to autonomy at anchor or while moored. Outside you will find practical features such as a sturdy swim platform with swim ladder, guardrails and a fixed crane/davit for handling the tender. The tender is a 3-metre inflatable with a 10 hp outboard engine with approximately 10 running hours as stated, ideal for shore trips or short explorations. With three anchors on chain and a manual anchor windlass, the vessel is also equipped for anchoring in various locations.
Maintenance and overall impression: ready to use with scope for cosmetic finishing
The vessel was hauled out in 2025 and treated with antifouling and new anodes. Photo documentation is available and invoices from recent years are present. Minor paintwork is known, consistent with the age and character of a steel motor yacht from this build period. Anyone looking for a 15-metre steel motorboat with flybridge, twin diesel engines, ample outdoor space and equipment that supports both cruising and living aboard will find this Patrolboat 1500 a distinctive and versatile option for touring, holidays and comfortable time on board.
