The Duke of Edinburgh is to visit Dover in December.
As Master of the Corporation of Trinity House, he will visit the Trinity House vessel Alert at Dover docks on 1 December.
He will also visit the Trinity Homes in St Clare Road at Walmer, Deal.
Alert, which has come into operation this year, is a Rapid Intervention Vessel, designed with buoy handling, wreck marking, towing and multibeam and side scan hydrographic surveying capability.
At 39.3 metres long, she is fitted with a range of high specification survey equipment and to the highest and most modern technical standards. With DP1 dynamic positioning, a service speed of 15 knots and a maximum speed of 17 knots, Alert primarily covers the southeast coast where she is able to respond rapidly to any maritime incident.
In addition, Alert can be utilised as a research platform with her large working deck that can be used for deployment of scientific equipment and sampling work. Available 24 hours a day and seven days a week, she has accommodation for an additional five people.
