I am indebted to the Controller of the Navy, Rear-Admiral W. H. May, M.V.O., for his permission to undertake the work, and to the Director of Naval Construction, Philip Watts, Esq., F.R.S., LL.D., for his kindly interest in the undertaking. The book is, however, not an official publication.

Although prepared primarily for naval officers, yet it is believed that the work will prove a useful introduction to the subject of Naval Architecture for apprentices and students at the Royal Dockyards and elsewhere.
