Thank you for your reply, and some lovely pictures of an extremely nice looking build.
My reason for picking this model was the attractiveness of it, twin props and the plant to fit I thought 🤔 and finally the overall weight. It has been suggested I make the Lady Wooes however, with the dimensions quoted its somewhat larger therefore heavier !!!! something I'm trying to control. I might have to bite the bullet and go for a single prop (Rosegarth) weight achieved. Previous builds have always been open launches and I thought a tug would make a nice change.
