Abstract
A marine vessel comprises an elongated hull that extends along a center axis from an aftward end to a forward end. A first transom portion and a second transom portion are located closer to the aftward end than the forward end. A first propulsion device is connected to the first transom portion and steerable about a first steering axis. A second propulsion device is connected to the second transom portion and steerable about a second steering axis. The first and second transom portions each has a mounting face that is set at a non-perpendicular outboard angle to the center axis. A controller is configured to steer the first and second propulsion devices inwardly towards a center of pressure of the marine vessel so that during certain lateral translations of the marine vessel the first and second propulsion devices can provide thrusts along axes that intersect aftwardly of the center of pressure.
