"Yachters are so dependent on electronics now that a lightning strike can be an all-out disaster.
Lot of folks don't carry standard navigation gear any more and have no idea how to use a sextant or a chart, or even take a bearing."
Then they are idiots! I've made runs up and down the East coast from NS to The Keys and the Bahamas and more under sail for over 40 years. We always have compasses (plural), sextant, books of logs, dividers, parallel rulers, a chronometer (and an old $3.00 Bullseye pocket watch)charts and tide and current tables and a battery powered rdf. We've seen some bad stuff but never needed rescuing because of equipment failure or otherwise (I wonder how they lost their mainsail?).
All the old hands know better, but a lot of these new guys think that backup is a second GPS. I crewed for my sister and ex-BIL back in the late 70s/early 80s, just up and down the Intracoastal in a little auxiliary sloop, but he was an old sailor and didn't really believe in all that newfangled stuff. I was a private pilot for years, so I can do all the basic navigation stuff . . . smart pilots learn how to manage with a mag compass and a protractor, too.
