When zippers refuse to zip.
In the category of things that you probably don’t think a lot about on land that make quite a difference at sea are zippers. Yes, zippers, along with just about everything else on a boat sailing in salt water, tend to corrode. And when they corrode badly, they cease to open. We have had metal zippers on multiple items seize up requiring us to either throw them away or live with the fact that they no longer ZIP. This is in spite of our applying lubricants, vinegar, heat and FORCE in a futile attempt to resurrect them.
It seems the best thing to do to prevent tragedies such as this is to apply some preemptive lubrication. That, or purchase items which only have plastic zippers. Too bad they’re not more common.
Tip: We have learned to leave dual zippers, as the bag in the pic below has, together in the middle as opposed to both at one end. This way if one side refuses to budge, we can still access whatever is in the bag.

Too bad the zippers tend to corrode down here.
