The Emerald Star cruiser company is to downsize its operations in Ireland, in what has been described as a major blow to tourism along the Shannon-Erne waterway.
Local politicians and business people say dozens of jobs will be lost as a result of cruisers being taken out of service and moved abroad.
The company currently employs around 50 staff at its three bases in Carrick-on Shannon in Leitrim, Portumna in Galway and Belturbet in Cavan.
It is understood that around 20 jobs are to go immediately in sales and marketing.
