What are the navigational criteria (beam, draft, etc.) for the river Liffey to steer from Dublin to Lucan or Celbridge?
A. The River Liffey is not under the remit of Waterways Ireland. Waterways Ireland is responsible for the the management, maintainance, development and restoration of the inland navigable waterways systems throughout Ireland principally for recreational purposes. The waterways under the remit of Waterways Ireland are the Lower Bann Navigation, The Erne System, Shannon-Erne Waterway, Shannon Navigation, Barrow Navigation, The Grand Canal and the Royal Canal. Dublin City Council should be able to help you with your query.
