the chap on the decks behind Nick is the self styled 'tank nut Dave' - he has a website of a similar/same name and often sits in that position on the Abbot as a second pair of eyes.
This story has reminded me of a report in The Derby Evening Telegraph over ten years ago where an Abbot in private ownership came off a road in the Peak District, rolled over & killed the occupants in the turret. I remember it said the mod had been bought in to investigate, surprised we didn't see a clamp down from that incident.
