We used to carry two spare anchors on deck. We have two on the bowsprit, ready for use.

Yes, that's four anchors. If we need to stay put, we can.
On the left is a CQR. ("Secure", get it?)
We kind of like it, but other people curse it out roundly. So we replaced it with a Rocna.
On the right is a Danforth. We've used these on other boats. They weigh nothing, and are kind of fun in that respect. But… There are places where Danforths are supposed to be ideal. As it is, it's just spare. We'd use it if nothing else seemed to grab.

There's CA, stowing them
Yes, she's standing in the lazarette. It's that deep.
Clearing the anchors off the deck reduces the visual clutter on deck. It's probably safer to have them below. It certainly makes it easier to move the mizzen running backstays without anchors underfoot.
Also.
There were things at the bottom of the lazarette that needed to come out and see the light of day for a moment. Perhaps get washed off. And also, discussed. "Do we really need this?" And "When would we ever need this?" Most things in there passed the test, and went back in.
