That depends on the ships Captain and officers onboard, frankly. If those officers didn’t care, or said they cared but didn’t prioritize the work, instead having everyone run around like crazy doing other things, that’s how you get this.

The captains have enough leeway, they can get the deck stripped and repainted if they prioritized it.

Of course, their commanders provide the environment that allows or requires them to do other things instead.

Probably too many other ‘must do’s’ and other problems.
