A multi-purpose boat has both land and water propulsion. The land propulsion wheels are selectively retractable, to lower the boat into engagement with ice. At least one ice fishing portal is provided in the bottom of the boat hull, and a portal cover is coupled with the boat hull to selectively open or close the portal. In some embodiments, a plurality of motive power sources are provided, as are various low-speed rudder systems, and a variety of canopies or shelters for various sporting activities.
