An enjoyable video to watch. But dubious docking practice.
As I understand it, the docking of ferries with open doors (while in motion) was banned in Europe after the Herald of Free Enterprise disaster?
Those with a lifting visor have no choice but to lift it before approaching the linkspan Brian - especially if the structure would foul the opening of it. Nearly all modern ferries today have 'wrap-around' bow doors that can be opened and closed after docking.
So long as the watertight inner door is left closed, then all should be well as the outer doors or visor are not water tight, only weather resistant.
Beyond that, some of the docking practices in some ports in the Med - and here I am thinking of some of the Greek Islands - would make your hair stand on end!!!!
