Understanding Boat Design
An Excellent boat design 101, all the glossary,definitions,explanations , and boat design syntax.
This is the first book u should buy if you are passionate for boats design,buidling, or owning.

Basic but effective
If you've been around boats for a while, you've noticed all sorts of shapes and hull designs. This book explains why.
Every design has strengths and weaknesses. Every hull is a compromise. Don't expect design tables or details, just good basic information

Too detailed, yet not detailed enough
I was disappointed in this book. I expected a well thought out, easy to understand description. The author starts out defining some terms, but omits others, and then describes things using undefined terms. By his initial definitions, one thinks "Good, this author doesn't assume I understand all the terms he will be using." Yet in the rest of the text he clearly considers that the reader knows a fair amount about boats and the terms used to describe them. Some drawings are missing important labels, and some explainations referring to drawings are missing important details, with a result that one is sometimes left perplexed. The book struck me as a quick gloss over of boat design with too much detail for someone in need of the grand overview. I don't think it had detail for someone actually interested in learning more about boat design. Someone interested in the quick basics would do better with other general sailing texts where simple principles of boat design are covered. Not sure what a better, more detailed text would be.

Covers the Basics..
This a great book if you are just starting to ponder the mysteries of boat design and its modern, which makes it better for beginners than Chapelle's books. IF, however, you are looking for more scientific/engineering sort of information, then you will be disappointed. Bottom line- it provides a wide survery of yacht designs, but does not delve into specifics enough for those of use who already know the basics. I would recommend it to anyone starting out in the field, but it is less technical than, say, Skene's Elements of Yacht Design.

Solid book for basics of boat design
I've have studied a fair number of books about design. This was the first I read and it's a good thing because it's not too hard to follow but it is definitely informative. It helps to understand design terminology and how a boat will perform based on its characteristics. I think I would have been frustrated had I begun somewhere else (such as Chapelle).

The focus is fairly broad. The designs are those most often seen on the water during the last 50 years (no brigatines, viking ships, or submarines). They are both power and sail, and both displacement and planing hulls. The size mostly seems to be boats of the "yacht" size (20 to 100 feet). Topics covered include styles of hull shape, line drawings, keels and rudders, layout, safety, construction materials.

This book will help you understand WHAT characteristics of a boat affect performance (and I don't just mean speed, because there is much more to it) and HOW they affect performance.

After reading and understanding this book, you will be able to better determine what to expect from a boat by just standing next to it and sizing it up. You will also figure out a few of the goofy things production companies do these days because they are focused on making boats that will be easy to sell, and not focused enough on making a boat that sails well. Make sense? Many modern designs have goofy characteristics that make a boat look good on paper and in an advertisement, but detract from performance, seaworthiness, reliability, and practicality when out on the water.

Bottom line: This book includes what I believe it should based on the title and the fact that it is ~150 pages long. It is very useful to someone want to own a boat, or get into boat design.
