I am greatly indebted to Kelvin for his help in establishing an accurate waterline plan, without which it would have been difficult to get much further with this project!
Because of the number of images I have to post for the whole project, I am going to describe it further on the 1250 Face Book page.
The image here shows how the build up of the hull began. I fixed strips of plastic to the hull either side using super glue. These were then built on with additional plastic strips which were fixed with liquid poly cement.
