Systems and methods for dynamic adjustment of depth indicators on marine vessel navigational charts

A navigation system for a marine vessel, comprising:

• a locating system configured to locate a global position of a center of rotation of the marine vessel;
• a transducer configured to sense at least one water depth measurement below the marine vessel, wherein the transducer is positioned at least one of a longitudinal transducer distance and a lateral transducer distance from the center of rotation;
• and
• one or more controllers configured to:
• receive the at least one water depth measurement from the transducer;
• determine an adjusted transducer position of the transducer relative to the center of rotation based on the at least one of the longitudinal transducer distance and the lateral transducer distance, and at least one of pitch or roll movements of the marine vessel;
• correct the at least one water depth measurement from the transducer based on the at least one of the pitch or roll movements of the marine vessel;
• and
• determine a chart error correction value for a depth chart based on the adjusted transducer position and the at least one corrected water depth measurement.
