Captain Bligh thanks for the reply, I think she is in Plymouth at present. I will have to find out exactly where.
Derek, well observed as always but no she has 2 Gardener diesels engines. The angel is more upwards than inwards. This photo at different angle shows it better.
Found a lot of information already. Bridgwater Museum yesterday, on the net day before. Breath 20.98ft that's 21 in my book, length is questionable, 100ft, 85ft, quoted but over what? eventually found 83ft at water line. I have a photo taken square onto & at water level, This will be scanned into my drawing program on layer1 on layer2 draw over the photo, remove layer1 & I have the elevation. Now I need a body plan look through my library to find a fit. I have 3 books on old sail with small drawings, also when ever I get a public library book I scan it into my computer. Copy right? Now all these are very small, so enlarge on computer, problem the lines are enlarged also. So I enlarge until lines about 1/8th wide print, trace in the centre of line, repeat until sections correspond to the with of the model. Usually only twice. The spacing of frames usually equal 10 plus half stations at each end but not always. Once I have built the hull all other drawing will be done on the hull. The elevation is not at the scale of the model , a double sided scale rule made, red side for elevation black for model.
