Congratulations to Erwin Schwartz of Juno Beach, FL who correctly explained why cruisers often put swivels between their anchor and the chain anchor rode. He emailed: ” When anchor chain runs over a bow roller and then is hauled in with a mechanical windlass, it develops a natural twist. Twisted chain falling into the chain locker can become tangled in interlocking coils so it can’t run out freely again when you next need it. A swivel lets the chain untwist as it is being winched aboard and will then fall into the chain locker neatly.”
