I was recently reading a reputable boating magazine that I respect when I came across a “rule of seamanship” that simply took my breath away, it was so wrong:
Reefing line(s) and hardware should be used to set a reef, not to take the full load. An easy way to reduce load is to use an earring. This is a length of line passed through the new clew and around the boom. A 3/8-inch line passed three times and knotted with a square knot serves fine. Once the reef is set, but while the sheets are still eased, simply lash the earring to the reefed clew. Slightly easing the reef line will put the load on the earring rather than the reef line. Because the reef line doesn’t hold the load, your reef lines won’t chafe through during a long passage.
