UK Border Force

As you may know, while the UK does have a coast guard, it is not much like the US Coast Guard. Nevertheless all the tasks remain. Their UK Border Force, which is part Customs, part TSA, and part Coast Guard, is their organization for addressing drug and alien migrant interdiction problem. Apparently they are using a patrol boat design which is a bit larger than the Webber class WPCs. Specs and video on the last link.
