Today’s bluejackets have to worry about modern 21st century problems while underway such as flakey internet signals, running out of pop, broken exercise equipment, 1980s tech in the CIC, chicken wheels, and lines for the washing machine. One thing they don’t have to fool with is the old 01 Division holy-stone train.
What is a holystone? Well here is the wiki on it and another mention here but suffice to say that this lump of sandstone, boiler brick, or even ballast weight was common to sailors from the 18th century through WWII. Its simple to use, just add seawater and sometimes a liberal coating of sand and scrub away at the teak decking of your old school battleship, cruiser, destroyer or frigate along with a dozen or so of your closest hammock mates under the close supervision of the bosun.
At the end of the day you would have a nice, clean deck that had been stripped of its top layer of grit and grime.
Of course today’s sailors much prefer nonskid.
Except for those who are assigned to the last two wooden decked ships in the U.S. Fleet, the USS Constitution and USCGC Eagle who just donated a spare one to the USS Missouri museum…However they still have plenty left over.
