Seminarschiff Fluxservice GmbH

What Seminarschiff Fluxservice GmbH does

Seminarschiff Fluxservice GmbH is a privately held Berlin-based limited liability company (GmbH) that operates two solar-hybrid event ships on Berlin and Brandenburg waterways: the Orca ten Broke, accommodating 40–200 guests for seminars, conferences, and corporate events, and the John Franklin, accommodating up to 40 guests for smaller events with an organic on-board kitchen and two roof terraces. The Orca ten Broke features a proprietary adjustable roof system that adapts to bridge heights and is billed as the first solar-hybrid conference ship developed in 2017; combined, the vessels have reportedly avoided 100 tonnes of CO₂ through solar-assisted propulsion. The company is led by Managing Director Felix Eisenhardt and employs roughly 10 staff.

Revenue is generated through three primary streams: (i) charter and rental of the two vessels for corporate events, private celebrations, and multi-day incentives; (ii) ticket sales for scheduled thematic cruises including Loungefahrt, Winterzauber, Mondscheinfahrt, and Badefahrt; and (iii) catering and packaged services, including standardized Business Conference Packages at €95 (half-day) and €109 (full-day) per person for the Orca ten Broke when stationary at home port Moabit, and a 2-day Havel Lakes cruise (Havelseen-Tour) priced at €5,800 for up to 30 persons. A mobile exhibition concept, "Wunderkammerschiff," runs periodically on the John Franklin.

Go-to-market is direct-to-consumer: customers request quotes or tickets through the seminarschiff.com website (available in German and English) and are consulted by phone, with event experts such as Timo Prinzhorn acting as the primary point of contact; prospective clients are invited to on-site ship tours. The primary customer segment is corporate and business clients (seminars, conferences, team events), supplemented by private celebrations and scheduled cruise passengers; named enterprise users include Prisod Wohnheimbetriebs GmbH. The fleet is operated from the home port at Alt-Moabit in Berlin-Mitte with routing flexibility across regional waterways.

Broad incumbents

• CroisiEurope: European river cruise company operating themed itineraries across multiple European waterways with onboard culinary and cultural programming. Comparable to Seminarschiff for its themed/experiential cruise positioning, though at much larger vessel scale.
• A-ROSA Flussschiff GmbH: German river cruise line operating multi-day themed cruises on the Rhine, Danube, and other European rivers. Comparable to Seminarschiff in delivering themed cruise experiences with onboard hospitality, though at multi-day scale and broader European scope.
• Köln-Düsseldorfer (KD): Major German inland waterway passenger shipping company with scheduled and charter services on the Rhine, Ruhr, and Mosel. Comparable to Seminarschiff in offering both scheduled sightseeing and private/event charters, but at much larger scale and on different waterways.
• Viking River Cruises: Global river cruise operator offering themed European river itineraries with curated cultural programming. Comparable to Seminarschiff in the themed-cruise concept (e.g., Mondscheinfahrt, Wunderkammerschiff) but on a far larger fleet and multi-day international scale.
• Avalon Waterways: European river cruise line offering themed multi-day itineraries with strong onboard hospitality and curated shore experiences. Comparable to Seminarschiff's themed cruise approach, especially the Havelseen-Tour multi-day concept, but with a much larger fleet.

Direct peers

• Reederei Riedel: Berlin-based passenger vessel operator offering harbor tours, line cruises, and private charters on the Spree and surrounding waterways. Directly comparable to Seminarschiff in geography (Berlin), customer base (tourists and corporate groups), and core service (chartered sightseeing cruises).
• Stern und Kreisschiffahrt: Established Berlin passenger shipping company running scheduled city cruises and event charters on the Spree/Havel, including themed tours. Competes with Seminarschiff for both tourist sightseeing and corporate/private event bookings in Berlin.
• Belvedere Schifffahrt Berlin: Berlin-based sightseeing and charter cruise operator serving tourist and corporate clients on inner-city waterways. Overlaps directly with Seminarschiff's scheduled cruise and private charter offerings in the same geography.

Emerging players

• Tauck River Cruises: Themed river cruise operator running curated cultural and culinary European itineraries. Comparable to Seminarschiff for its differentiated, experience-led cruise product rather than mass-market cruising, though operating multi-day international voyages.

Regional players

• Haveltourist: Berlin/Brandenburg waterway cruise operator running scheduled tours and charters on the Havel and connected lakes. Comparable to Seminarschiff's Havelseen-Tour multi-day product and overlapping with Berlin leisure cruising demand.
