On the bow If you store your anchor on the bow, make sure it is tightly secured. One on trip we lashed an anchor down, but the boat. The anchor flew off the roller and smashed the underside of the pulpit, before dropping into the water. To secure the anchor, insert a strong stainless steel pin through the anchor at the tripping eye and at the shackle end. When choosing an anchor, make sure it can be tightly pinned down on your bow roller.
Some boats have anchor lockers, which allow the anchor to be stored below deck.
The anchor, however, should be tied down in the locker. An anchor stored loosely in the anchor locker can do a lot of damage. After it is tied down, use a small fender as a wedge to hold the anchor in place and keep it from rattling or banging as your boat heads into a seaway. An anchor locker should be located as far aft as possible, with good watertight gaskets and a drain. In a seaway, water can fill a bow locker easily.
