There are calls for more convictions for ring buoy vandalism after 11 were reported missing in Cavan and Monaghan last year.
Eight were reported to Monaghan County Council and three to Cavan County Council.
A further seven in County Monaghan had their rope missing or stolen.
A new Bill is in the process of being passed to make it easier for Gardai to prosecute people found to have vandalised equipment such as ring buoys and defibrillators.
Speaking to Northern Sound News, CEO of Irish Water Safety John Leech said more prosecutions will lead to less vandalism.
