Dramatic footage has emerged of a kayaker being rescued after he was hit by an extremely powerful wave off the coast of Ireland earlier this month.

The video, filmed off the island of Inishmurray, shows the moment the wave strikes, carrying the kayaker for quite some time, prompting a rescue.

He later wrote online: "The first day of the ISKA Symposium 2016 at Rosses Point Sligo and we headed out to the island of Inishmurray in nice conditions unfortunately around the back of the island I got caught out about 40ft from shore and it turmed into a real rescue incident.

"My training with Belfast Kayak Club and the ability to stay calm helped me through the incident along with the fabulous rescue by the WISKA Crew who not only rescued me but got back what remained of my boat(2/3rds) as the front end sheared of in a final impact."

"Lucky for me I had got out of the boat just in time -- Not the biggest wave that has ever hit me but the force was like nothing I had experienced before as it flung me over and took me side ways towards the rocks at an amazing speed/force," he continued.
