A portable marine anchoring device maximizes holding capacity while anchored into the ground. The device is fabricated from lightweight aluminum.

The present invention refers to a hybrid vessel with a ballast system in which the position of the cabin (102) is changed vertically, from emerged to submerged and vice versa, according to the decision of its operator. Thus, the present invention describes a hybrid vessel with ballast water system comprising at least one cabin (102) and at least one main tank (101) of ballast water, and the tank (101) is connected directly to the CAB (102) or partially above the water level.

The present disclosure describes recreational watercraft that provide a ballast system and an open platform passenger deck. An example is an aluminum hull including a ballast system to regulate displacement by the recreational watercraft and an open platform passenger deck as an integral upper surface to the aluminum hull. Multiple sides, continuous from the aluminum hull, include a stern side, a bow side, a port side, and a starboard side that surround a perimeter of the open platform passenger deck. An inboard power plant is located within a stern portion of the aluminum hull to propel the recreational watercraft.

The present invention relates to a lightweight composite propeller for an outboard motor, wherein the propeller has a separate hub and blades which are easily repaired when damaged, improves fuel efficiency because a lightweight composite material is used therefor, and is easily manufactured in large quantities.

An embodiment includes an open/non-closed hull collar assembly that is shaped to increase encapsulated volume of a hull. The hull collar assembly may include a hull collar structure and a foam module. The hull collar structure may include a gunwale, an outboard boundary, and an inboard boundary. The outboard boundary extends in an outward lateral direction from a lower hull portion and extends in a longitudinal direction from the lower hull portion such that at least a portion of the hull collar structure is at least partially included in a freeboard portion of a boat hull. The inboard boundary extends from the gunwale a portion of a distance to a deck such that the hull collar structure is at least partially open or non-closed to an inner hull volume. The foam module is comprised of a non-expansive, closed cell foam. The foam module is shaped for disposition within the hull collar structure.
