Aha: there's a long answer to the question, which is more fun than a short one: And had I not stopped to listen to 'More Or Less' on Radio4, I might have finished before David 🙂 Anyway: Aylesbury Canal Society were long-term occupants and leaseholders of the canal basin close to the centre of Aylesbury, (Canal Society's picture) and initial proposals for redevelopment of the basin had insufficient compensation for the Society needing to move out, and interesting-negotiations (as in The Legal System, Lawyers-from-Big-Houses, etc) led to a brilliant new replacement facility at Circus Field, a mile outside Aylesbury town centre. The design specifically included room for Fulbourne's 71'6" to be hauled up the track into the drydock (wetdock is parallel and alongside in the new building). Inside the drydock, it is a tight fit, hence the protection of rudder from the door, and expensive door mechanism from the rudder, which is provided by the fender as in the earlier picture. So my short answer was to be "to protect the door shutter" 🙂
