Marine propulsion control system and marine vessel capable of performing dynamic positioning control

A propulsion control system for a marine vessel including at least one power source to generate thrust, the propulsion control system comprising:

• a memory;
• and
• a controller coupled to the memory and configured or programmed to:
• control movement of the marine vessel by the at least one power source;
• and
• while performing dynamic positioning control of the marine vessel, perform deceleration control to reduce a bow direction speed of the marine vessel;
• wherein
• the controller is configured or programmed to end the deceleration control when a duration of the deceleration control reaches a predetermined period of time or more, and the predetermined period of time varies according to a number of the at least one power source provided on the marine vessel.
