The 2020 Irish Rowing Championships and Coastal Championships have been cancelled due to the restrictions around public health guidelines.
Both events were due to take place later this month, but in line with the government's latest guidelines regarding Covid-19, it was decided that neither could proceed.
Rowing Ireland, along with other sporting organisations had hoped that the number of people allowed at indoor and outdoor gatherings would be increased to 500, but the cabinet have decided to delay again in the face of an increase in Covid-19 cases in recent weeks.
Taoiseach Micheál Martin said the size of crowds gathering will remain at 200 for outdoors and 50 for indoors and that the evidence will be reviewed again in three weeks' time.
"Consideration was given to postponing the event until later in the hope that the number of attendees allowed would increase but it was felt that there was no guarantee this would happen and the committee wished to bring certainty to all concerned," a Rowing Ireland statement read.
"In addition, many of our younger rowers will have returned to school at the end of the month."
President of Rowing Ireland Eamonn Colclough urged people to think creatively in light of the setback.
"We are all disappointed with the cancellation of the Irish Rowing Championships, Irish Coastal Rowing Championships and other events," he said.
"Around the country, we know that our athletes along with their coaches have been training hard and their club committees have worked tirelessly to ensure the safety of our members.
"We always knew that our contingency plan would be subject to Public Health guidelines. We encourage clubs to continue to think outside the box when staging local events. As a sport, we can continue to row and compete subject to 200 person limits."
