High-penetration, high-holding power, stowable marine anchor

Abstract

A weighted chisel-shaped tip is attached to a generally triangular and concave fluke. Extensions are attached to either side of the fluke, proximal to the aft edge and extending outward from the centerline of the fluke. A roll bar is attached to the extensions. A shaft is attached along the centerline of the top of the fluke, extending perpendicularly from and forward of the top of the fluke. The shaft provides an attach point for an anchor rode. A plurality of fasteners enables assembly and disassembly of the marine anchor.

 a fluke having a leading edge, an aft edge, a centerline, and a plurality of holes configured to accommodate assembly and disassembly of a shank assembly to said fluke assembly; and 
 two extensions located and attached proximal to said aft edge of said fluke, one of said extensions being located on either side of said fluke and extending outward from said centerline of said fluke, each said extension having one or more holes designed to accommodate assembly and disassembly of a roll bar assembly to said fluke assembly; 
   a roll bar assembly, comprising:
 a roll bar; and 
 two flanges, one of said flanges attached to either end of said roll bar, each said flange having one or more holes configured to accommodate assembly and disassembly of said roll bar assembly to said extensions of said fluke assembly; 
   a first plurality of fasteners designed to accommodate assembly and disassembly of said roll bar assembly to said fluke assembly;   a shaft assembly, comprising:
