Mystery of tragic seaman Simon.
Simon Pollard, 23, was acting chief engineer on the NATO coastal research vessel Leonardo.
His body was found early on Saturday on board the ferry Oglasa, which was docked next to the Leonardo in the Tuscan port of Portoferraio.
Simon's grandfather, Frank Pollard, yesterday paid a glowing tribute to his beloved grandson.
Frank, 72, of Greenock, Renfrewshire, said: "Simon was like a son to me and to lose him is a devastating blow.
"I got a call on Saturday afternoon to say he'd been found dead. It was very difficult to take it in.
Proud "He'd studied so hard at the nautical college in Glasgow to get where he was at such a young age. I am very, very proud of him.
"He served his time on the Clyde and he was doing so well in the Merchant Navy. He was working with a contractor in Italy who were doing defence work.
"He'd already heard that his contract was to be renewed in November and he was very happy with things.
"I last spoke to him on Wednesday when he phoned and said he felt he'd landed on his feet with the way everything was working out."
Simon lived with his mum Liz Fisher, 45, in Gourock. She left for Italy early on Sunday morning.
Reports yesterday said an initial post-mortem examination confirmed Simon died due to "illness".
