The Duke of Kent is to name a new RNLI lifeboat at a service in Essex.
Walton & Frinton RNLI's new Tamar lifeboat, will be officially named the Irene Muriel Rees, by his Royal Highness on Thursday.
The Duke, who is President of the RNLI, will tour the station and meet past and present crew members and fundraisers.
He is also visiting other lifeboat stations in Suffolk at Southwold, Aldeburgh and Ipswich and in Essex at Harwich and Clacton.
The Tamar is the latest lifeboat from the RNLI, with the most up-to-date technology.
It is capable of reaching 25 knots, compared to their previous lifeboat, the Tyne's 17 knots, and has a range of 250 nautical miles.
Andrew Ashton, RNLI divisional inspector, said: "Royal visits of this magnitude are rare and we hope the Duke will really see for himself the kind of commitment that the volunteers in East Anglia have.
"It is a wonderful opportunity for current and past fundraisers and lifeboat crews to meet the Duke and demonstrate the high level of dedication we have."
