The company sold 60,000 bonds at EUR 1,000 each this week. It was targeting sales worth between EUR 50m and EUR 60m.
It aims to replace some of its current loans and "optimise" its balance sheet, it said.
The company wants to expand its charter activities and plans to return to the river cruise business, as well as reduce debts.
It opened a EUR 20m credit line in 2011.
