Abstract: A boat hull includes a pair of spaced apart cavities formed in the bottom thereof. Mounted within each cavity is an electric trolling motor. An air purge system is provided for purging air from each cavity when the boat rests on a water surface. Additionally each cavity is closed at front and rear ends and is open from the bottom. The depth of each cavity varies from front to rear with a maximum depth occurring generally intermediately between the ends. In operation each trolling motor generates a propulsion stream of water that is directed generally rearedly and downwardly from the rear end of each cavity.

Abstract: A recreational boat comprising a boat hull having a bottom and a top deck. Formed in the bottom are two spaced apart elongated cavities that extend substantially the entire length of the boat. Disposed in each cavity intermediately between the front and rear of the boat is an electric trolling motor. Each electric trolling motor is independently controlled by a foot pedal mounted on the top deck. Hence, the boat is propelled by the trolling motor and can be steered by independently controlling each of the electric trolling motors.

Abstract: A propulsion and steering system for dual motors mounted to a boat, especially of the trolling type, which incorporates a pair of foot pedals which are electrically connected between a battery and the motors and which are operable to independently control the direction of thrust and speed of the motors so that the motors are used to both propel and steer the boat.
