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 boats 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.
