The guy that owns the Tartan in the berth next to mine has just returned after an absence of several weeks.. now with more knowledge I asked him a bit more about his boat.
It is 12 months old/new and a 3400. He says he has no knowledge of the issues and thought the Tartan had bought out Novis..... I did not ask further as he is a good pen neighbour and I don't wish to bring about ill feeling.
I did hear (2nd hand) from our local rigger that he (the owner) had to have some of his safety wire replaced as it pulled clean out of the swaging when someone leaned against it.
