  • Patent number: 7013829
    Abstract: A semi-submersible hunting vessel is provided. A hunter can move the vessel to a designated hunting area and partially submerge the vessel to reduce the visibility of the vessel and hunter to flying game. The vessel includes a hull, at least one ballast chamber, a dry chamber, and one or more pumps for filling and evacuating the ballast chamber. In another embodiment, the vessel contains fore and aft ballast chambers for added stabilization. Additionally, the vessel may be equipped with a motor, which vertically adjusts to the level of the water by sliding up or down along one or more float guides, along with camouflaging, such as a canopy or a device for installing natural vegetation.
