POWER MODEL BOATS is intended for the "average" modeller, and does not pretend to advise the expert. As such it should prove a welcome source of guidance and inspiration to the beginner, the dabbler and the not-so-expert. It is written entirely from practical experience, with a certainty that success will attend the efforts of anyone who follows the procedure described employing care, patience and common sense. Model boating has advanced tremendously in recent years, the growth of interest inducing trade support, which in turn has promoted more interest, leading to more support, and so on. The would-be model boat builder can therefore rely upon an ever-growing range of materials, parts, accessories and facilities, so that no elaborate workshop equipment is necessary for completely satisfying results. The hobby is expanding fast, and now embraces such branches as radio-control, perhaps the most enthralling of all its many departments. A wide variety of power units is available, ranging from simple electric motors to single and twin i.c. engines, and more elaborate four-strokes right up to advanced marine units in the realm of the expert. The book guides the enthusiast happily through the pitfalls of his progress. Within its covers will be found a wealth of information on all forms of hull construction; materials in common use; suitable tools; the different types of motor and their best employment; simple approach to radio control; boat fittings; couplings, shafts and propellers; superstructures; painting and finishing; unorthodox models, including submarines; and a valuable selection of "do's and don'ts."
