Made the trek to Lowestoft, and all seems now to be well with the boat. Dealt with visa issues with the very helpful Border Force patrol boat, and contacts within British Immigration who helped solve a problem with common sense and goodwill. Much appreciated (and unusual, I think!).
Good ringing in Lowestoft, with a ground-floor 8. Likely the last ringing I will get to do for a long time, and how I will miss the many friends I have made ringing around the country.
Awaiting good weather (at sea: the weather in land is wonderfully warm and sunny, but this brings an on-shore sea breeze and very uncomfortable swells in the direction I have to go). Then on to Harwich and await arrival of Nick and Chris to take me across the Channel.
