The adventurer departed on Monday 4 June in an 18-foot sea kayak, aiming to paddle up to 12 hours and complete a marathon distance of 30 miles each day to finish the challenge in under five weeks.
His kayak will be loaded with more than 50kg of essential kit and supplies, including lots of food - Jones will need to consume at least 5,000 calories each day if he's to keep up the pace and beat the rough seas and strong currents around the Irish coastline, especially in this weather.
Jones - a veteran of expeditions including whitewater kayaking in Nepal and rowing across the Atlantic - hopes this latest adventure will raise €10,000 for the Children's Sunshine Home and LauraLynn House for children with life-limiting conditions.
The attempt evokes memories of last year's solo circumnavigation of the island of Ireland by Elaine 'Shooter' McKenna - the first woman from Northern Island to achieve such a feat.
