MS Asbach is a tourist boat which is operated by the Köln-Düsseldorfer shipping line.

The bow propeller by De Gerlien van Tiem has its own 230 kW strong MAN engine.

When fully loaded, draft is still only 1.25 m.[1] Asbach was built as Marksburg by the Dutch Shipyard De Hoop in Rijnwaarden in 1995 and 1996.

Therefore the shipyard attached a pontoon of about 10 m long to the stern, but this did not prevent Asbach from hitting the bottom during launch.

The Köln-Düsseldorfer was now quite certain that the boat was OK, and that her sailing qualities had not ben adversely affected by the launch incident.

From 10 May Marksburg started regular service, primarily between Koblenz and Rüdesheim am Rhein.

In December 2008 Asbach was sold to the shipping line's 100% subsidiary KD Europe S.à r.l in Luxemburg.
