Sir David Attenborough has said he was “extraordinarily emotional” as he launched a polar research ship named after him into the water for the first time.
The 92-year-old broadcaster said the ship, which the public voted to call Boaty McBoatface but which was officially named the RRS Sir David Attenborough, could be key to the preservation of the planet as it was launched into the River Mersey from the Cammell Laird shipyard in Birkenhead.
“I’ve never seen a ship of that size get down a slipway and there was something very noble about it and very emotional. Irresistible.
“And, to think that it’s going to go to the other end of the globe and do such valuable work and carry so many people from this country who will be working to find out all they can about the working of our planet is a marvellous thought.
“I am more honoured than I can say that that wonderful hull has got my name on it.”
Sir David said: “The perils facing this planet are far, far greater than they have ever been in its entire history, or at least since the end of the dinosaurs, certainly for the last few million years.
“There’s nothing to compare with the perils we are facing, not only in the scale but in the speed at which they are happening and of course we now know that we are responsible for a lot of these changes that are taking place.
“You have to know what they are before you know how you can fix them so this ship is going to be key to the future salvage of our plant or at least its preservation.”
More than 124,000 people voted to name the vessel Boaty McBoatface in a public poll, but that name was vetoed and it was instead named after the broadcaster.
However, Boaty lives on, in the form of a miniature, unmanned, yellow submarine on board the boat, which will be operated by the British Antartic Survey (BAS).
In a speech ahead of the launch, Ms Perry said: “This ship will help us with the tools we need to understand what the world will look like if we let climate change run away and what we need to do to stop it.”
The ship was blessed by Bishop of Birkenhead Keith Sinclair before its launch and a field gun was fired by soldiers from the Royal Artillery 103 Regiment as it entered the Mersey.
Once in the water, tug boats pulled the ship into the wet basin where construction work will continue.
