An anchor bra provides an easily removable and replaceable cover over a protruding boat anchor, thereby protecting other boats and people from damage by an exposed anchor. The anchor bra is preferably formed of a buoyant and pliable marine grade plastic that covers a boat's anchor when it is raised. The anchor bra is secured in place by adjustable straps that are fastened to the boat's gunwale or railing. The anchor bra is made in various sizes to accommodate various anchor shapes and sizes.
