The former Weaver Boats proprietor, who will be familiar to many veteran Shannon boaters, aims to raise money for the North West Cancer Hospice and the Ethiopian Cancer Squad via his latest endeavour.
Originally planned for this June Bank Holiday weekend, Kennedy seized on the perfect rowing conditions last Sunday 29 May for the five-mile run from Carrick-on-Shannon to the Boyle River.
But he's still welcoming donations for his chosen charities, both close to his heart.
After spending some time under the care of the team at the North West Hospice, Kennedy has first-hand experience of how important this service is for those in need, according to his daughter Úna who's been getting the word out about his plans.
