I turned your picture right way up [such a pain being north of the line, eh :-)?] and enlarged it. There is enuff data in it that you can develop a shear plan with a view to building a "bread and butter" hull
, at say 1 inch to the foot scale, that will be so convincing that no-one will know you hadn't a full lines drawing :-) For a model for the kiddies, that should suffice. But be warned - you could get hooked on this sort of thing :-)!
A lot depends, of course, on how familiar you are with the draughtman's craft as exercised in days of yore, and on how accomplished a woodworker you are, and on what tools you have available. There are several good articles and YouTube clips to be had by asking the all-knowing Ms.Google. As for getting out a lines drawing, if you don't know the techniques, I can explain it to you. This drawing can be fairly rudimentary, for if you use the B&B method for making the hull
, the glue lines will give you a wonderful visual guide to making and keeping the hull fair as you carve it. Particularly if you make the "lifts" (the laminations of boards) vertical so the glue lines in the hull blank coincide with the "buttock" lines on the drawing.
Anyway - don't let lack of drawings stop you. You can make your own and once you've got the basic dimensions down on paper [vellum, actually :-)] the detail will fill in quite easily and rapidly from stuff you can remember about your own boat
and from things you can deduce as the drawing develops.
If I can help further, don't hesitate to ask.
