This book focuses on the design and engineering process for both power and sail. It look at why your boat is designed and built as you see it now; it explains why it has certain characteristics both positive ans negative; and gives formulas for finding hull design pressure and speed predictions.

Principles of Yacht Design has established itself as the standard book on the subject for practising designers, naval architecture students, discerning boat owners as well as the boatbuilding industry as a whole. The fifth edition is completely revised and expanded. It examines every aspect of the process of yacht and powerboat design. The new edition includes new findings from recent research in aero and hydrodynamics, as well as covering the most recent changes to building standards. The authors have used a newly built 41-foot performance cruiser to demonstrate the practical application of yacht design theory. This new edition includes photos of the building process and detailed explanations.

This straightforward guide is designed to take the novicestep-by-step through the stages of designing both power and sailingboats, explaining the reasons behind the procedures and using typicallines plans and working drawings to help understanding. Since it was first published, How to Design a Boat has proved itself to be a bestseller. 'A brilliant little book.' Workboat World 'Thoroughly recommended.' Motor Boat & Yachting

Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

This handbook takes the novice step-by-step through all the stages of designing both power and sailing boats so that, with no previous experience, they can produce a worthwhile design. It includes working drawings and typical line plans from a wide range of vessels. The calculations require only basic mathematical skills and the text is written in a simple and straightforward style.

Sail Performance, based on C A Marchaj's classic Sailing Theory & Practice, has established itself as the standard work on the subject and is now acclaimed as a milestone in sailing literature. From wind tunnel tests which he has conducted, Tony Marchaj describes how the factors of wind speed, sail area, sail shape, sail setting, the hull, angle of heel, wind gradient and steadiness of the wind all affect sail power, and why certain rigs are superior in power and efficiency to others. Sail Performance is a major work which is acclaimed for its analysis of the factors that contribute to an efficient sailing rig.
