Abstract

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.
