The Barefoot Navigator: Wayfinding with the Skills of the Ancients
赤脚领航员：古人技巧的寻路
Jack Lagan
杰克·拉根（Jack Lagan）
The Barefoot Navigatorintroduces the navigation skills of the ancients--methods using the sun, sea, wind, and stars, and even the flight patterns of ocean birds.The Barefoot Navigatoralso shows today's sailors how to apply these methods to augment--and in the case of emergency, replace-their modern navigation systems. And it not just for emergencies--sometimes it is just plain fun to create a simple astrolabe or polar stick and confirm what your GPS tells you.
赤脚导航员介绍了古代人的导航技巧-使用太阳，海洋，风和星星的方法，甚至是海鸟的飞行方式。赤脚导航员还向当今的水手展示了如何应用这些方法来增强-在紧急情况下，替换其现代导航系统。而且这不仅适用于紧急情况-有时，创建一个简单的星盘或极地棒并确认GPS会告诉您的东西很有趣。
Polynesians managed to populate an area of ocean larger than North America simply by analyzing clouds, currents, and wind direction--how did they do it? In the first portion ofThe Barefoot NavigatorLagan introduces these ancient seafarers and their powerful, accurate--and seemingly simple--navigation techniques. We also learn that the Vikings routinely traveled on the notorious stretches of water between Iceland, Greenland, and Scandinavia--no charts, no GPS; it seems mind-boggling but Lagan shows us how. The second section ofThe Barefoot Navigatorteaches how to combine these ancient techniques--and even construct the simple devices if we desire-with today's modern navigational devices, especially in emergency situations (loss of power, loss of signal), to ensure a constant grasp on your vessel's location--no matter what.
通过分析云，洋流和风向，波利尼西亚人设法在比北美洲更大的海洋区域中进行人口分布-他们是如何做到的？在《赤脚领航员》的第一部分拉根（Lagan）介绍了这些古代海员及其强大，准确且看似简单的导航技术。我们还了解到，维京人通常在冰岛，格陵兰和斯堪的纳维亚半岛之间臭名昭著的水域上旅行，没有图表，没有GPS；似乎令人难以置信，但拉根向我们展示了如何。《赤脚导航器》的第二部分介绍了如何结合这些古老的技术-如果我们愿意，甚至可以构造简单的设备-与当今的现代导航设备，特别是在紧急情况下（断电，信号丢失），以确保持续不断掌握船只的位置-无论如何。《赤脚领航员》
Interlacing fascinating history with useful advice and enjoyable writing,The Barefoot Navigatoris unlike every other navigation reference out there.
