Prince William has praised the "fantastic" work of search-and-rescue volunteers during a one-day visit to Belfast.
The former lifesaving helicopter pilot mixed with dozens of fellow rescuers and named a new boat for the Lagan Search and Rescue Service after watching an exercise at Belfast Harbour.
The British Royal said: "It is fantastic what you are doing."
He named the new inflatable-style boat the Ray of Hope, after fundraiser Ray Atkinson who helped raise the money for it - christening it with a dash of Bushmills whiskey.
He also watched a demonstration of a rescue in the steel-grey waters of the harbour amid heavy rain.
As he was presented with a bottle of Bushmills he told volunteers: "You guys deserve this after that."
Mr Atkinson, from Edinburgh, runs a project reusing surplus office furniture in Belfast.
Desks and chairs from large companies are sold to dealers and the funds go to good causes.
Lagan Search and Rescue was established in 2012 and has saved more than 50 lives, Mr Atkinson said.
"So now they have the capability of saving twice as many people."
Earlier, the prince visited the offices of the Mental Health charity, Inspire. It provides services on both sides of the border and it also has a programme to help young people develop resilience and coping mechanisms through sport.
Among those associated with the initiative are the former Armagh GAA player, Oisin McConville and Sarah Booth, the captain of the NI women's football team.
