Hi Martin and welcome to the forum.
There are a number of model 'sailing' experts here, but, like you I only did full-size (Ospreys, Redwings and Bosuns mainly).
I think your model could be suitable for radio control and I've heard that "Nylet" do very good sails. My next project is likely to be a sailing cruiser – I'll follow the thread with interest…
I expect the others will be able to advise on rigging materials etc. There are so many dinghy classes and it's hard to say if it's a scale model or not. I rather suspect it may be semi-scale, or, perhaps a free-hand design ?
My uncle used to own and race a fixed keel boat like this: "Dragon" class if memory serves correctly.
Good luck with your project and Happy New Year,
Dave C
ps Looks like Malcolm and Ray beat me to it !
