Abstract: An anchor for small watercraft. It is extremely lightweight, and can be stored in a very small space. The anchor consists of a pear-shaped fabric ballast container. This container is made up of a number of matching side panels and a circular bottom disc. A set of four metal or composition flukes attached to the ballast container near the bottom and at the widest part of the container. Each fluke is about 9-11? long, ¾? wide, ½? thick, with an angled tip at one or both ends. The flukes are thus deployed by weighting the bag with material like gravel or sand, which forces the flukes to protrude sharp angle from the ballast bag. When filled with material, the anchor approximates the function of traditional fluke or bell anchors. The anchor can be turned inside out for self-storage, requiring no additional storage container.

Abstract: A propeller that has curved vanes attached to the blade tips and to the blade body. The curved vanes at the blade tips act as a nozzle. However, because the “nozzle” is attached to the propeller blades, there is no need to modify the boat motor to accommodate it. In this design, the nozzle turns with the propeller. A full blade ring or guard can be formed and attached to the blades, if desired. This ring not only enhances the nozzle effect, it also protect people and items from getting drawn up into the blades of the propeller. This improves propeller safety as well. The propeller blades can have a number of different vane configurations. Moreover, there is a design that allows for variable pitch of the blades.
