Last post 6 months ago, so it hasn't got much further and looks to have hit the buffers.
My personal experience is that both yards that I have used recently did a very good job at what they were asked to do, but one left the boat in one hell of a mess afterwards, because the workers did not clear up their mess and it was not inspected by the boss. The other one also did an excellent job, but again there were things that did not work after refitting. I have heard some appalling tales of shoddy work on boats, with some even coming close to sinking. If the garage industry worked like this, they would be out of business in no time.
Although I no longer service my own car, I do service my boat, because I hate anyone else getting their hands on her.
