by W.J. Daniels and H.B. Tucker
with a Preface by the late C.N.Forge
Referred to in Rudder Magazine as the "Dixon Kemp" of model boat building we are please to be able to offer this fine comprehensive work.
From the Introduction--It has been the aim of the authors in compiling the present treatise to explain every process in the designing, building and sailing of model yachts in the clearest possible manner without leaving anything to the imagination. Everything has been detailed step by step, and all technical terms explained as they occur. If this book helps to smooth the way of the recruit and assist him to enjoy the fascinating and instructive sport of model yachting, it will have served its purpose and repaid its authors. Very completely illustrated with seventeen large pocketed plates (too large to reproduce here wth any clarity).
