Expand : Thinking as there isn't a page for the relief fleet boats that are currently active i.e. where a station has received a new Tamar boat and their old Tyne has been stationed as relief. I (MTimmins92) have a full list of relief fleet boats, currently only ALB but will soon be ILB as well. I would need to verify some boats that I am unsure of but this would be minimal.
Update : List of All current boat numbers and names that are on active station service - this is through the lifeboat station list page
