All About Powerboats: Understanding Design and Performance by Marshall, Roger;

Rövid leírás:

"Clear, insightful, easy to understand. This book is a must for powerboaters."--Bill Sisson, editor, Soundings

"Roger Marshall shares three decades of accumulated boating knowledge so you can cut years off your learning curve!"--Dean Clarke, executive editor, Sport Fishing

Your plain-language guide to powerboat design and performance

What's the difference between a modified-V and a deep-V hull? Or a planing hull and a displacement hull?

Why does boat A have flared topsides and not boat B?

How can I tell if a boat is adequately powered?

How do I judge a boat's seaworthiness just by looking at it?

What are the advantages or disadvantages of twin engines or a stern drive?

Get answers to these and all your questions about powerboat design and performance in All about Powerboats.

If you want to know what makes a boat fast, slow, stable, unstable, seaworthy, comfortable, or ideal for the things you want it to do, here's a perfect place to start. Longtime boat designer Roger Marshall tells you what you need to know about hull design, engines, drive trains, steering systems, comfort factors, safety features, and construction methods. He translates the jargon, explains the key concepts, and offers a wealth of insights into what makes powerboats tick.
