Each line of data in a current coefficient file has the following format:
Relative floating body/current heading, Ccy, Ccz, Ccθ
This line is repeated until current coefficient values are specified for all headings. Relative floating body/current heading in this context is defined as the angle of incidence of the current relative to the floating body axes; refer to Definition of Wind and Current Directions for a more detailed definition. Ccy, Ccz, and Ccθ are respectively the current coefficients in surge, sway and yaw at a particular heading.
•*CURRENT COEFF is used to specify current coefficients used to determine the current loading on a floating body or moored vessel.
