A steel displacer where the question is not what needs to be done - but what has already been done. This Crown Trawler 830 „Queen Mary III“ was extensively refitted in 2022 and fitted with a complete set of new tarpaulins in 2024. You are not taking over a classic used boat, but a system that has been consistently maintained and further developed over the years.

Not a series boat, but a piece of Dutch shipyard craftsmanship: built in 1985 by De Koning-Keyzer in Leiderdorp - a shipyard that has stood for steel displacement boats with substance, durability and independent lines since the 1960s. It is precisely this construction method that forms the basis for a refit such as 2022 to make any sense at all - because the structure and quality of the hull are designed to last for decades, not just years.

The Vetus diesel (52 hp) runs for around 2,000 hours and was last serviced in 2025. What is striking is not so much the mileage as the handling: maintenance after every trip - a standard that translates directly into reliability and overall condition. With a fuel consumption of around 2 liters per hour, the boat remains economical even on longer journeys.

A key difference to many comparable models is the energy system: three lithium batteries (280 Ah each) in combination with a solar panel enable longer mooring times without shore power. This significantly extends its use - from a classic weekend boat to a self-sufficient displacer. Two helm stations (inside and flybridge) with hydraulic controls ensure full control in all weathers. The maneuverability is remarkable even without a bow thruster - a sign of the well-balanced hull and drive design.

Below deck: a cabin with four berths, 1.90 m headroom, diesel heating, galley with gas hob and refrigerator. The boat is designed for real use - not just for short trips.

In short: a classic steel displacement boat from 60 years of Dutch shipyard history - extensively refitted, with a modern lithium energy system and a level of care that can be seen in this boat.

The most important facts: 9.00 m × 2.85 m × 1.20 m | Year of construction 1985, refit 2022 | Vetus 4-cyl. diesel, 52 hp | approx. 2,000 operating hours | Condition: well-maintained | 3 previous owners | Lithium energy system (3× 280 Ah) + solar | Location: Berlin
