In the morning we expected to mosey on down to the tunnel entrance mid morning and be there in plenty time, but in stead the phone rang while we were still in bed and they were expecting us to be there already. We cast clothes on and ropes off and approached the tunnel. There were volunteers there to greet us as we approached and one asked me if we wanted water. I said I didn’t think we needed it, then he mentioned that a full tank kept the boat marginally lower in the water, so I took that point and pulled forward to the water point. I got on with sorting that while Shane went to investigate inside the engine compartment from where there had been some very unhappy noises and a lack of battery generation. Since he seemed busy I engaged with the staff, answering the questions from the man with the clipboard, about the boat dimension; observing the large light being mounted and discussing safety regulations such as the fitting of helmets and life jackets. He showed me a well scratched helmet. Shane as designated driver had a high viz vest too. They regaled me with tales of those deemed incompetent or foolish who had taken chunks of stonework off the walls or run out of diesel during their transit through the tunnel. Soon the tank was full and the hose stowed, the safety equipment on, the boat measured and the pilot, Trevor, was aboard. As I cast off, I was told that the view from the front was very good so I sat there, ready to be official photographer.
