Well it is Royal Navy! Its not every day you see a Royal Navy vessel at a motorway services! Survey Motor Boat SMB Shackleton is seen on a low loader at Taunton Deane Services on the M5 on 29th March 2019. Presumably returning to Devonport or maybe Falmouth? https://www.youtube.com/watch?v=-mwzX9JBPBc
