Query: THE ESSENTIAL GUIDE TO SAILING!...

If you only have time or space for one sailing magazine, this would be it! From the professional to the enthusiastic beginner, Sailing World is a must for the sailing afficianado. Where else can you find a balanced, well-written magazine that not only covers collegiate sailing, new products, America's Cup, international sailing, new boats, expert techniques, and intelligent editorials. I have found that other sailing publications try to be "too much" and they lose their focus in either large and countless advertisements to pay for their large format, or juxtapose a beginner's article against a highly technical article for experts, leaving the reader confused. This is the only sailing magazine I subscribe to and will continue to. You must have this magazine!
