I was intrigued to see this cottage had a vigorously flowering New Zealand kohwai tree lockside when we passed through at this time of year, the only one we ever saw in England. And intrigued also when we passed through in September that it did not have a single pod, as here every flower nearly produces a pod. Either they had been plucked off, or perhaps there were none of the pollen gathering birds to pollinate the flowers. Is that the kowhai with its golden yellow flowers to the right of the bottom picture?

Over coating the zinc with a high integrity coating system reduces the exposed sacrificial zinc surface, thus prolonging it's life. For inland waterway use magnesium is the preferred anode material because of its even greater reactivity. So adding easily replaceable magnesium anodes, even further reduces the work that the zinc surface has to do in suppressing corrosion of the, all important steel. The corrosion preference becomes: Magnesium first Zinz second. Steel last. The offshore oil industry added a huge amount of knowledge marine protective coatings practice, as the coating life very largely determined the safe life of these very considerable structures with massive contingent liabilities.

4 days up and 4 days back is very compressed for a delightful waterway.
