During his multimonth cruise aboard his Fales 32 Navigator motorsailor, he didn’t tow an inflatable dinghy, even though everyone else does. Instead, he towed something much more valuable — a proton magnetometer. The towed “fish” of a proton mag is designed to detect ferrous metals — iron — and one day while cruising near an island, he got a hit — a big one. The next thing I knew, I was on a plane down-island to see what the commotion was all about. It turned out that my friend had stumbled upon not just one but several old anchors, and after further research, he realized he’d discovered the wreck site of several ships dating back to the golden age of piracy. According to the manifests, they were loaded with millions of dollars’ worth of gold and silver from the Tierra Firme, aka Spanish Main. And so the treasure hunt began.
