This really is a wonderful book. It is aimed as a "must-have reference for every code-loving, boat-loving, information-loving kid!" but don't let that stop you. It is a large book using slightly textured paper for each flag making it lovely to handle. On the page opposite the flag the author explains its meaning in an interesting way and adds the morse code and semaphore signals plus a little snippet about various types of boats. Although aimed at children it would be an excellent and memorable way to brush up on all the nautical codes for anyone of any age. It has just been pointed out that the flags are printed on both sides so in an emergency.......! A graphically stunning, first-ever volume of nautical codes for children This extraordinary visual reference is an introduction to maritime communication through nautical flags, along with morse code, the phonetic alphabet, and semaphore signaling. Today's system of international maritime signal flags was devel-oped in the 19th century, and is still used for communication between ships, or between ship and shore. Each flag, boldly colored for visual distinction at sea, stands for a letter as well as a phrase relevant to seafaring. The resulting code is both beautiful and functional, inviting readers to code and decode messages of their own! Created for ages 6-8 years
