A man accused of killing a friend in a boating incident had been drinking lager before the fatal incident, a court heard.
Jason Robinson was on a diving and fishing trip to Scotland in May 2009 with a number of others including Garry Henaghan.
Mr Henaghan died after a rigid inflatable boat Mr Robinson was said to be driving ran aground on Calve Island at Tobermory Bay.
A jury was told on Tuesday that Mr Robinson and the group had been at a bar before the accident, but that the 42-year-old was not drunk.
The roofing-contractor faces a charge of culpable homicide at the trial at the High Court in Glasgow.
Mr Robinson, of Cramlington, Northumberland, had travelled north in 2009 with his brother Wayne, Mr Henaghan and John Binney. The court heard it was the type of break they had done "numerous times".
They took an inflatable boat that Mr Robinson and his brother had previously purchased.
On May 18, 2009, the men went diving near Oban, but Mr Henaghan remained on the vessel to fish. The group eventually all sailed into Tobermory later that evening, where they visited a bar.
Wayne Robinson gave evidence on Tuesday and admitted having around four pints of lager at the pub.
Prosecutor Jonathan Brodie QC asked the 44-year-old: "Did you see Jason drink?" The witness replied: "Yes."
Mr Brodie went on: "Did you see him drink more than one pint of lager?" Mr Robinson said: "Yes."
The men later headed back towards their base in Lochaline, Argyll with Jason Robinson at the controls of the boat.
Mr Robinson recalled them moving and then there being a collision. He described it as "an almighty bang".
The witness was asked had he seen Calve Island before the crash and he said: "Not exactly, no."
He told how he was struck forward and that two of his teeth were knocked out along with other injuries. Mr Robinson recalled Mr Henaghan being missing from the boat before he was found lying on nearby rocks.
Advocate depute Mr Brodie asked: "Did he appear injured?"
Mr Robinson replied: "Yes, I climbed out of the boat and sat next to Garry. I remember the noise of the tubes deflating on the boat. I also remember Jason in contact with the RNLI and then a lifeboat came."
Mr Robinson said he believed the speed of the boat was "approximately 15mph" when it crashed. He added that it was "a guess".
Mr Brodie said: "Do you agree that Calve Island poses a navigational hazard for a boat leaving Tobermory in the dark?"
Mr Robinson said: "Yes."
The jury was later told that Mr Henaghan had not gone diving on the trip as he was "not quite comfortable" with the area.
Mark Moir, defending, asked the witness if he had felt drunk after leaving the bar that night. Mr Robinson replied: "Certainly not."
Mr Moir said: "What about your brother?" Mr Robinson replied: "No."
The accused Jason Robinson denies the charge. The trial, before Judge Rita Rae QC, continues.
