Tributes have been paid to a young father from Cornwall who was killed after a motorcycle crash in Orkney on Saturday evening.
Jon Csehi, 29, was working on the Scottish islands on a marine energy project for Falmouth-based Mojo Maritime Ltd.
No other vehicles were involved in the incident, which occurred on one of the island's Churchill barriers.
Mr Csehi, from Probus, leaves behind his five-month-old daughter Emily and wife Kim who described him as a "devoted husband and father, who surrounded himself with family".
She said: "Tell the world what an amazing man he was and what an amazing husband and father he has been."
The 29-year-old had been in Orkney a week before the accident occurred, where he was working as a project manager on the installation of a hydro tidal turbine.
His childhood friend and colleague, Simon Hindley, said the former Truro College student, who grew up in Par and attended Fowey School was a "true friend".
The gifted athlete and rugby player served in Afghanistan for Royal Marine 42 Commando and in 2007 came second in the Atlantic Rowing Challenge with friend Nick Histon.
Mr Hindley said: "Jon was a true friend, mischievous, great fun, kind with a keen eye for an adventure. He will be missed."
The young father had joined Mojo Maritime after studying a renewable energy degree at the University of Exeter, which he started after leaving the marines.
The company closed its office yesterday as a mark of respect.
Managing director Richard Parkinson said: "The entire Mojo team is absolutely devastated at losing one of our brightest stars.
"He excelled in everything he was tasked with. He was incredibly talented and we had huge plans for the future."
