If you raced offshore back in the seventies and eighties you probably wore Line 7 foul weather gear and a Lirakis harness.
The less said about the non-breathing heavy PVC former—it was waterproof but that did not help much since we stewed in our own juices—the better.
But the latter was the first widely available harness that stood a chance of not breaking under load, or maiming the wearer.
Stephen Lirakis, the deeply experienced ocean race crewman who designed, and for many years made and sold this harness, has a very cool website of photos from back in the glory days of Ocean Racing between amateur crews, and some from more recent races, too.
A highly recommended way to waste an hour when you should be doing something else…I would know.
