Alice saw a book on Amazon and as I didn't have it, ordered it. It was called 'Model Boat Building' After a month, it arrived from the US of A and turned out to be a reprint of a book originally published in 1905. Very interesting. Details of building a cutter. Straight stem, counter stern, cod's head and mackerel tail. Gaff rigged, gaff topsail standing rigging set up with deadeyes. Typical of the period. How to build alternatives, bread and butter, planking on frames and, something different, built with plates of soldered tin sheet.
Obviously there was no RC, so instructions on how to rig a boat so that she would sail well downwind and reaching and again for beating to windward. Rudder is set by fitting tiller into a rack. Another thing they say to do is to strengthen the stem with a piece of sheet brass wrapped around the stem and stretching an inch or so each side. Just in case you hit anything!.
Also 'how to build a transatlantic liner', again tin plate construction, clipper bow and counter stern. Not only that, but how to build a steam engine and boiler for her.
Another chapter on how to build a vertical engine for a steam launch. In this they suggest that every piece is made in wood , then passed over to an engineering firm to have all the pieces cast and returned to you for putting together.
All together an excellent £10 worth, really good read, little practical use. but, thank you Alice.
