Abstract: A marine anchor is described which has a shank having a leading end for attachment to a cable and a general double-bladed ploughshare shaped fluke fixed to the shank with the blades disposed symmetrically about the median plane of the shank. The leading ends of the blades terminate in a single apex and the trailing ends of each blade diverges outwardly from said medial plane, each blade having a generally inwardly dished shape. The blades can be curved or consist of at least two flat angled surfaces.

Abstract: An ice fishing device having a cylindrical sleeve that is resilient and radially compressible to enable the ice fishing device to adapt to a variety of different size holes in the ice and members on the cylindrical sleeve to vertically and securely support the ice fishing device within the confines of a hole in the ice. A small charcoal chamber attaches to the side of the ice fishing device and holds sufficient charcoal to produce sufficient heat to keep the water in the hole from freezing yet keep the ice fishing device sufficiently cool so as not to burn a fishing line located therein.
