Younger son is a paint inspector and works in the world of superyachts. He has just flown to Hamburg for a project meeting in connection with the repaint of a 130-odd metre yacht. His printer went u/s before he flew out so he emailed me a couple of docs to print, which amounted to over 50 A4 pages of specifications for the job. The work is highly labour intensive, and at that level of expertise wages are high and labour costs are considerable. When I asked him how much the job was going to cost he said he wasn't sure, but not less than one million euros. Puts the £900k for the Voyager into perspective. Also that £900k is not lost to the economy. A lot of it goes to provide well paid work to skilled employees, boosting the local economy (presumably around Cambridge), and of that a fair amount is going to come straight back in the form of income tax, VAT on the paint etc.
