Are the dimensions available or do you have to buy the Mary Rose book?
To answer your question:-
It depends what you want!
I don't think they are published elsewhere, but say you have a stave of known length and wanted to make a Mary Rose replica of that length. I could look through the data and give you dimensions for one of the bows of that length.
But to be honest IMO they are only a guide unless you don't mind what the finished draw weight will be!
I tend to build to a required draw weight, if tillered appropriately and with an eye to the shape of the MR bows you'll end up at the right draw weight with the right appearance.
