I took my old 1966 Coronet 21DC (power, not sail!) to Dartmouth for a week's holiday some 22 years ago - the only time I've ever visited - my wife was pregnant with our daughter at the time - and we had a fine time cruising around the area. The guy on the fuel berth remarked on the boat, I said it was in a sorry and tatty state but slow progress was being made - he said "look around, there are hundreds, if not thousands of boats here, and most of them never, ever move, at least you're using yours", which cheered me up a bit!
It is a beautiful area, and the model is a wonderful representation - keep up the good work!
