There are two kinds of vessels regularly running during the season between Vienna and Bratislava on the Danube River. The hydrofoil (rocket) is a technical landmark produced in the USSR. If you are interested in the technique, choose it. The rocket has long served - it is an indestructible Soviet machine. The rocket passes through the locks in Freudenau. Cruising takes a little longer.
Twincity liner is more modern and its advantage is that it leaves in Vienna right in the center nearby Stephenplatz.
