More than 250 boats are to set sail from Greenock to Glasgow in celebration of the 2014 Commonwealth Games.
The Commonwealth Flotilla, a special event organised by the Royal Yachting Association Scotland, will see more than one thousand people dock at Pacific Quay this July.
Ships from around the UK and Northern Ireland will meet at James Watt Dock in Greenock on July 25, and will make the 17 nautical mile journey, around 32 kilometres, to Glasgow the following morning.
James Stuart, Chief Executive of RYA Scotland, said: "The Commonwealth Flotilla will be the largest assembly of boats that the Clyde has ever seen, and we want to make sure that as many sailors, non-sailors and spectators have the opportunity to make history by being part of this once-in-a-lifetime event.
"The Homecoming Muster and the Small Ships Race will deliver over 250 boats to Greenock, before the mass Flotilla makes its way down the Clyde to Pacific Quay.
"The Commonwealth Flotilla will mark the culmination of hundreds of journeys to Scotland and Glasgow, and each crew will have their own reasons for making the journey and their own story to tell.
"We estimate that more than one thousand people will make the journey and we know the people of Glasgow will turn out in similar numbers to witness this unique event."
New pontoons are also set to be installed at Pacific Quay to allow the boats to berth.
