The family of Timmy MacColl gathered at one of the world’s oldest Royal Navy ships, the frigate Unicorn, in Dundee, Angus, a popular tourist attraction yesterday.
A photo of the missing sailor, surrounded by yellow ribbon and a poster will be on display on board the ship which was first launched in 1824.
Timmy’s mother, Sheena and his grandmother, Molly MacColl, 75, both of Killin, Perthshire, put the photo in front of the Unicorn’s figurehead on the upper deck of the warship.
The yellow ribbon campaign began when the 27-year-old Leading Seaman went missing seven weeks ago from HMS Westminster while it was docked in Dubai, UAE.
Gosport, where Timmy is based, was turned into a sea of yellow by worried friends and neighbours as news of his mystery disappearance spread.
Yellow ribbons have also been tied to doors, gates and trees in his home village, Killin, Perthshire, where he grew up.
The dad-of-two’s uncle, Colin MacColl, a Tayside policeman based in Dundee, said the family is keen to keep the public aware of Timmy’s disappearance.
Mr MacColl, 52, travelled to Dubai with Timmy’s wife, Rachael, 25, her police officer uncle Neil Cunningham, 45, and mum Sheena, three weeks ago.
Dubai police chief His Excellency Lt General Dahi Khalfan al Tamim showed the family CCTV of the sailor outside the pub-club Rock Bottom where he was last seen in the early hours of May 27.
The police chief also revealed that officers had traced the driver of the taxi Timmy is thought to have been put in by shipmates at around 2am.
The driver, asked to take the sailor back to his ship at nearby Port Rashid, claimed to have got lost inside the vast docks and when he stopped at a tea shack to get directions Timmy got out the cab, it is claimed.
But an extensive land and sea search of the port aided by Royal Navy divers and underwater remote vehicles from a minesweeper which ended last week failed to find any trace of Timmy.
Last night Mr MacColl revealed: “After the meeting with the police in Dubai everybody was at their lowest point emotionally. But we were taken out to the port that night and saw for ourselves how it was almost impossible for anybody to get to the water’s edge.
“The fact that the searches have failed to find anything just raises more questions about what has happened to Timothy.
“There has been no new information. We are urging anybody who knows anything no matter how small to contact Dubai Police.”
CID in the Emirate are still investigating Timmy’s whereabouts from around 2.30am on the morning of May 27.
The huge investigation team has already been re-interviewing witnesses. Members of the HMS Westminster crew have also been quizzed again and their statements handed to Dubai officers.
The Westminster has been on operations East of Suez, pirate-busting in the Indian Ocean. It had a recent stop-off in Bahrain.
Timmy had spent his last-known day at the Dubai Seafarers’ Mission where it’s known he only had two pints of beer before his best friends left him there at around 5pm.
They were going back on duty and Timmy sent back his credit card with them.
He eventually left the Mission at around 11.30pm and arrived at the Rock Bottom Café opposite Dubai’s Burjuman Mall.
There, bouncers say they took him out of the busy club because he fell asleep in front of the bar.
Two colleagues then claim they paid the taxi driver Dhs70 (around 6.50GBP) to take Timmy back to the ship which was only a 15-minute journey away.
However, the family, who visited Dubai to retrace Timmy’s last-known steps, were told by the police that the sailors may have paid the driver only Dhs25 – two Dhs10 notes and a Dhs5 note which is similar in colour to a Dhs50 note.
The fare would have been around Dhs 30.
His family has vowed never to give up searching for him.
HMS Unicorn was built for the Royal Navy in Chatham dockyard. She spent most of her working life patrolling the seas around Dundee. She is now one of the six oldest ships left in the world.
Timmy is a father-of-two and was due to return to Portsmouth at the end of August, in time to see the birth of his third child.
