I was very interested to read the discussion. Could I add that I owned Dinsdale from 1979 to 1981. My first National 12. I was still a teenager! A beautiful boat in immaculate condition. I sold her to Barry Tipping in 1981 but she came back into our family in 1984. My sister, Sue Pelling sailed her from 1984 until 1987. Very pleased to hear that she is back in loving hands. When we owned her she was red and had lovely sapele decks, with contrasting sycamore gunwhales.
