The Dublin Docklands Development Authority has called for expressions of interest for new "water-based businesses" on the Liffey.

The authority said it wanted to maximise the "amenity potential" of the Liffey as part of an overall river regeneration strategy.

It wants to hear from the operators of ships, craft and other vessels that would be moored in "the heart of Dublin" and would provide recreational and tourist facilities. Suggested ventures include hotels, restaurants and retail businesses. Arts uses and community or education projects are also seen as a possibility.

The authority said "any other exciting, viable proposals" would be considered. "The significance of the Liffey to the Docklands regeneration project cannot be over-emphasised," said Paul Maloney, chief executive of the authority.

"This part of Dublin used to be the centre of our maritime industry and now we are putting out calls to bring some of that bustle and life back to the river," he added.

Initiatives already under way as part of the regeneration strategy include the Liffey Voyage tour service, which carries more than 3,000 passengers a month, and the purchase of a Famine replica ship.

The authority has also redeveloped the Dublin City Moorings as a berthing facility for "super-yachts".

The closing date for applications under the latest phase of the regeneration strategy is August 25th.
