More Information
Summary:A watercraft propulsion system (100) includes a bow thruster (BT), at least two propulsion devices (OM), a translation/bow turning operator (8) to apply a translation command to translate a hull (2) and a bow turning command to turn a bow of the hull (2), and a controller (50) configured or programmed to drive the bow thruster (BT), and drive one of the at least two propulsion devices (OM) forward and another of the at least two propulsion devices (OM) in reverse while controlling the steering angles of the at least two propulsion devices (OM) so that propulsive force action lines (71s, 71p) of the at least two propulsion devices (OM) cross each other in the hull (2) in a translation watercraft maneuvering mode to translate the hull (2) in response to an operation of the translation/bow turning operator (8). The controller (50) includes a calibration mode in which calibration is performed for the translation watercraft maneuvering mode.
