Thanks for doing that update so very quickly. I'd thought I might do it when I got home next week! 
I'd agree the shore line on the map wasn't quite where the shore was on Tuesday but I don't know whether it varies by season. I had only opened my app to see if the jetties were mentioned to find out whether they related to the flying boat base in the war, so hadn't looked the other side of the peninsula or elsewhere on the shore to compare. We were just visiting for the day so I'll not be back.
