Prince William and Kate Middleton will carry out their first official engagement in Wales when they visit Anglesey later.
The couple are the guests of honour at the event to name a new RNLI lifeboat at Trearddur Bay.
The Prince is an RAF search and rescue pilot based at RAF Valley on the island where the couple also share a house.
The Atlantic 85 lifeboat will officially be named the Hereford Endeavour at the event this afternoon.
Christopher Pritchard, senior helmsman at Trearddur Bay, said: “Having Prince William and Miss Middleton name our new lifeboat is especially significant to us.
“As Prince William is a pilot with the RAF search and rescue force just down the road at RAF Valley, we also welcome him as a colleague who works with us to save lives at sea.”
Volunteer crew and fundraisers were hard at work yesterday preparing the lifeboat station.
Aubrey Diggle, Lifeboat Operations Manager, said: ‘The station’s never looked better – we’ve done a lot of cleaning and polishing!
“There are still a few things to do before the big day but we’re getting there. Now we just have to keep our fingers crossed on the weather!”
During the engagement, the royal couple will meet RNLI volunteers who funded the new boat at the charity’s branches at Leominster and across Herefordshire.
The boat, the most advanced inshore rescue vessel produced by the RNLI, will also be put through its paces for the royal party and guests.
