For years, inflatable PFDs have provided sailors with a comfortable way to stay safe without wearing bulky gear. But there are more than a few stories of unwanted deployments. And how would you pull the jacket’s back-up manual “inflate” tab if you were knocked unconscious while getting tossed in the drink? Mustang Survival’s new Auto Hydrostatic Inflatable Personal Flotation Device automatically inflates once the unit is submerged in more than 4 inches of water, but won’t deploy prematurely if it is subjected to rain, waves, or humidity. Available with or without a built-in harness. From $249.99. Mustang Survival, 800-526-0532, www.mustangsurvival.com
