Clint Willis, the anthologist de l’extrème who brought us High, takes to the brine for a wide-lens collection of tales from the high seas in Rough Water. Much of it aims for the outer reach as portrayed in Sebastian Junger’s Perfect Storm. Armchair navigators will thrill to the dangers and codes of honor that intermingle in the surf, as in Robin Knox-Johnston’s stiff-upper-lip telling of his solo circumglobal sail: “I was in the lead and stood a slight chance of w (more…)

Made from hand-blown glass — The earliest barometers were simple glass bulbs with a spout that helped ancient seaman predict storms. Water moving up the spout means low pressure with potentially stormy conditions, while high pressure pushes the water down to the bottom of the spout. This style of barometer is just as effective today, and provides a decorative method for predicting weather via changes in air pressure. — When good weather approaches, the liquid in the ball is pushe (more…)
