Danforth/fluke Anchors

Cqr/plow/delta/wing anchors hdg. Danforth/fluke anchors. Every boat i have ever purchased pre-owned has come with a danforth/fluke anchor. My only conclusion for why this is, is because they are the most affordable anchor around today, although this affordability is coming into question as more anchor patents expire. The fluke anchor performs quite well in mud and sand. When set correctly, the flukes can penetrate the bottom with a lot of force, resulting in excellent holding power. The downside is that outside of mud and sand, the fluke has very limited holding ability in bottoms such as kelp, rock, coral, etc.. When being set in mud or sand, these anchors do have a reputation for occassionally dragging along the bottom. For day boaters or to use as a secondary anchor, the fluke anchor is a suitable choice. For anyone boating overnight where an unset anchor has more dire consequences, another choice of anchor style should be considered.
