This was the moment a tourist failed to backflip off a boat on a Bali beach while trying to impress onlookers on July 7, 2019.

Footage shows the attempted summersault, where on completion of the full rotation the amateur gymnast catches his head on the side of the boat with serious vigour.

They said: "We were on tranquil Gili Trawangan, heading to even more tranquil Gili Meno.

"We observed the beauty of the island before we got off, but didn’t know what was coming next!

"I decided to do a back somersault off the moving boat in flip flops to the sand below."

We were on tranquil Gili T - heading to even more tranquil Gili Meno - we observed the beauty of the island before we got off...but didn’t know what was coming next! I decided to do a back somersault off the (moving) boat - in flip flops - to the sand below.

Next thing my head was bouncing off the side of the board and I was out on the floor!

I was with my parents (Chris and Shirley) visiting me in Bali from UK and my aunt visiting from Melbourne!

Seems like a rested couple of days is now enforced rest!

Happened 5pm Sunday 7th July.

Thanks for checking it out!
