In an anchor the stabilization arms transversely extending in the plane of the flukes are constructed as bars of quadrilateral cross-section having forwardly directed faces forming an acute angle with each other instead of rod-shaped. These bars are so formed that with a considerably smaller length of the stabilization arms the same stabilizing effect is obtained.
A very light-weight boat anchor includes a pair of penetrating flukes connected together, an anchor shank pivotally attached to this pair of flukes, and a mechanism for limiting the pivotal movement of the shank relative to the flukes. Both the flukes and the shank are made of light-weight alloy metal and the total weight of the anchor does not exceed 250 grams and is preferably less than 150 grams. The flukes include edge ribbing extending along upper and lower edges thereof and relatively thin metal webbing extending between this ribbing.
An anchor comprising an exterior bale and having two fluke planes in a horizontal plane that lie vertically parallel and in a horizontal plane are separated by vertical ribs uniting the horizontal planes at an angle of 90.degree. and forming with them open spaces between the fluke planes that allow the passage of marine floor material through the entire length of the fluke planes area. Stops elements are to either side of the fluke plane and control the burial angle rotation of the fluke in relationship to the bale.
