Abstract: An auxiliary vehicle powered vessel. The vessel is configured to carry an auxiliary vehicle, such as an all terrain vehicle, preferably on its deck. The all terrain vehicle can be driven onto and off of the vessel. When in the vessel, the auxiliary vehicle engages a transmission that transfers power to the vessel's propulsion system. When the vessel reaches its destination, the auxiliary vehicle can be driven off the vessel. Later, the auxiliary vehicle can be returned to the vessel and used to power the vessel again. The preferred embodiment of the vessel is provided with a “mud boat” propulsion system to allow operation in shallow waters. The preferred embodiment of the vessel is also designed to overcome the stability challenges posed by the high center of gravity that will arise from carrying objects such the auxiliary vehicle in the vessel, particularly if such objects are transported on deck.
