Revitalizing and re-galvanizing our anchor chain. We mark it every 50 feet and use a clever mnemonic; Rub Your Body With Grease representing Red @ 50′, Yellow @ 100′, Blue @ 150′, White @ 200′ and Green @ 250′ and then red/yellow/red @ 300′ which represents an imminent dive to recover the chain. Much fun is had by replacing ‘Body’ with your favorite word starting with ‘B’.
