The commissioning strategy will be implemented by using a proprietary customer-facing software embedded within a software module of a newly installed dynamic active control system for a new marine vessel (and a new hull type). The software-controlled commissioning strategy is configured to automatically determine the appropriate feedback gains for the marine vessel by controlling the deployment of the water engagement devices while simultaneously measuring and capturing the data generated from the resulting list angle, roll angle, roll rate, and yaw rate changes associated with the deployment. The software driven commissioning strategy is further configured for auto-calibrating the following functional parameters of the new marine vessel: (1) Speed-Based Bias Adjustments (SBBAs), (2) Roll Overall Gain (ROG), (3) Pitch Overall Gain (POG) and (4) Yaw Rate Gain (YRG) of the marine vessel. ## Claims ### Claim 1 A software-based commissioning method to automatically determine a plurality of feedback gain parameters for a new marine vessel, comprising: installing a dynamic active control system having an user-interface connected to a software module; wherein the software module is communicatively and operatively connected to at least one pair of water engagement devices; prompting a user to activate and instruct the system to asymmetrically and symmetrically deploy the at least one pair of water engagement devices; measuring and processing data related to the motion of the vessel generated from the asymmetric and symmetric deployment of the at least one pair of water engagement devices; analyzing the processed data for: automatically characterizing a functional relationship between the asymmetric deployment of the at least one pair of water engagement devices and a list angle generated for a certain vessel speed, automatically characterizing a functional relationship between the asymmetric deployment of the at least one pair of water engagement devices and a yaw rate generated for a certain vessel speed, and automatically characterizing a functional relationship between the symmetric deployment at least one pair of water engagement devices and a trim angle generated for a certain vessel speed; automatically converting the functional relationships to a plurality of vessel-specific first feedback gains; and storing the plurality of vessel-specific first feedback gains within the system of the marine vessel. ### Claim 2 (depends on 1) The software-based commissioning method of claim 1, further comprising the steps of performing a series of static tests to determine;
