Hi Charlie very interesting. I remember visiting a professional model builder, Malcolm Darch at his home. Malcolm made us most welcome and showed us his current builds. These were 2 identical super yachts each about 4 - 5 feet long. One was to go in the full size super yacht in a glass case and the other was to be a working model with RC.
This was aver 20 years ago, but a memorable visit.
I have one regret as he had a Basset-lowke cargo boat he had been asked to restore and due to being busy he offered it to me to do the work.
I was part of a 3 man yacht crew and we had sailed there and moored in Salcombe harbour. The dinghy we used had such a low freeboard that carrying a valuable item was not on.
Ah well!
regards Roy
