New canal and Shannon bylaws being proposed by Waterways Ireland are causing concern amongst some boat owners and sports groups.
Suggested changes include the reduction of mooring times, changes to winter mooring and a tax on all businesses operating on the Shannon.
"The Royal Canal is 140kms long and there's plenty of space for all of us, and what we're suggesting really is that different areas are marked out with different kind of priorities, I suppose. For long-time Longford boater Liam Finnegan, who is part of the Shannon Lakes and River Group, there is concern around a proposed €200 registration fee on the River Shannon.
"Another big thing is winter moorings. People avail of winter mooring in places like Carrick-on-Shannon for the winter months and under these proposals, that's being done away with," said Mr Finnegan.
