As an example, here are three things that I benefited from immediately. After you read the book, you'll have your own list.

1. The mental aspect of boat preparation. You have to do whatever it takes to KNOW that your boat is fast and ready to win. Otherwise, when you're going slow you'll be making excuses instead of finding what's wrong and fixing it.

2. A killer diagram showing spinnaker pole positioning for reaching. This diagram makes it completely obvious what to do, but it's TOTALLY contrary to the "prevailing wisdom" among most of the folks I sail with. But the first time I used Buddy's position, boy did we point with that chute!

3. A great description of "feathering" the boat upwind on the beat.

As always, the winning combination is read, then sail, read some more, sail some more, then repeat. If you don't go on the water to practice, no book can help you.

The downside is that the book was written before the new racing rules came into effect, so be sure you're fully familiar with the rules before taking Buddy's advice on tactics that rely specifically on rules for their validity. (For example, in one circumstance the advice to a leeward boat is to luff up quickly, and "tap" a windward boat, fouling them out of the race. You'll be on thin ice if you try this in the new rules, with their clear emphasis on the importance of avoiding collisions.)
