If you've ever watched the children sail their boats on the Serpentine, in the Luxemburg or even Central Park where the sport is just in its infancy, you know how hard it was to tear yourself away. There's a subtle fascination to it that we simply don't outgrow. Thomas Darling, a Naval Engineer and Constructor has also taught manual training where many boys are being taught to make their own models. The book starts with very simple models and plans, gradually it goes on to the most advanced types showing the boys or men (reader, I should say, for there is no age or sex limit to these enthusiasts who are forming model yacht racing clubs all over the world) not only how to build but design their own yachts. The list and descriptions of the various models and the reasons for recommendation add a particularly nice feature which most of the books omit.
