A vessel (1) comprises a hull (2) including a bow (3) and a stern (4) and has a length-to-beam ratio which is smaller than 10:1, preferably smaller than 5:1. The hull (2) has a vertical centre plane (CP) extending in a direction from the bow (3) to the stern (4). At each side of the centre plane (CP) the vessel (1) has at least two azimuth thrusters (6) including respective propellers (6a), which azimuth thrusters (6) are located next to each other in transverse direction of the centre plane (CP). Each azimuth thruster (6) drivably coupled to its own prime mover (7).

A boat includes a hull, a deck, and a bow hatch. An engine compartment is provided in the hull. The deck is mounted on an upper portion of the hull. The deck includes an air inlet port that opens rearward to supply air to the engine compartment. The bow hatch is attached to the deck. The bow hatch includes a wall that faces the air inlet port.

Example steering control systems and methods for multiple devices are provided herein. A system includes a trolling motor assembly having a propulsion motor and a steering actuator and a sonar assembly comprising a transducer assembly and a directional actuator. The system further includes a user input assembly that is configured to detect user activity related to controlling operation of the trolling motor assembly and operation of the sonar assembly. The system further includes a processor that is configured to determine a direction of turn based on user activity, generate an electrical turning input signal indicating the direction of turn, and direct either one or both of the steering actuator and the directional actuator, via the turning input signal, to adjust a direction of either one or both of the propulsion motor and the transducer assembly accordingly.

A marine vessel maneuvering support system includes a steering apparatus including a wheel portion supported rotatably with respect to a hull, mode switches provided on the wheel portion and operable to execute lateral thrust generation modes to generate a thrust that moves the hull in a lateral direction, paddles provided on the steering apparatus and operable to cause a thrust to be applied to the hull in a front-rear direction, and a controller configured or programmed to control at least two propulsion devices and execute the lateral thrust generation modes in accordance with instructions from the mode switches. The controller is configured or programmed to control at least one propulsion device of the at least two propulsion devices to generate or change the thrust in the front-rear direction acting on the hull in response to operations of the paddles when the lateral thrust generation mode is being executed.
