Abstract

An aquatic vessel (500) includes a hull (20) and two engines (30, 50), the engine (30, 50) outputs being rotationally couplable to corresponding propeller units (332, 352) which are mounted so as to be angularly moveable in respect of the hull (20). The vessel (500) includes a control unit (70) for controlling operation of the engines (30, 50) and angles (.alpha..sub.1, .alpha..sub.2) of the propeller units (332, 352) with respect to the hull (20). The vessel (500) is configurable to operate in a first mode wherein directions of thrust developed by the propeller units (332, 352) are mutually substantially parallel for propelling the vessel (500) through water, and a second 'fishing' mode of operation wherein the directions of thrust developed by the propeller units (332, 352) are configured to mutually diverge with respect to a longitudinal axis from a rear end of the vessel (500) to a forward end thereof for providing the vessel (500) with a turning characteristic (160) in operation. The control unit (70) is configured to receive in operation user-instructions for commanding the control unit (70) to operate in the second mode for causing the propeller units (3320, 352) to be angularly orientated in a divergent manner in respect of the longitudinal direction. The control unit (70) controls rotation of the vessel (500) by controlling power coupled from the two engines (30, 50) and delivered to their propeller units (332, 352) and forward/reverse coupling of the propeller units (332, 352).
