One can get by without referring to charts, but they are an important tool and a part of good anchoring gear, and a skilled mariner would not choose to anchor without them. [41], In 1887, the Delta Gamma Fraternity adopted the anchor as its badge to signify hope. Bruce anchors can have difficulty penetrating weedy bottoms and grass. 4. 7.
