Prototype of triple-screw 1800hp diesel tug for Danube.
L: 66m, B: 9.2m, H: 3.2m, D: 1.6m.
Built in 1954 by Slovenske Lodenice Komarno/SK for Ceskoslovenska plavba dunajska (CSPD Bratislava). Did not prove well in service so serial production did not start. Krivan towed barges on all then navigable Danube: from Regensburg/DE to Izmail/UA; retired in late 70's and was laid-up for long time in Bratislava.
In 1999 sold to an entrepreneur, repaired, slightly rebuilt and repainted and since 2001 serves as restaurant in Bratislava/SK.
