The conventions used in WAMIT are as follows:
•The definition of wave heading is transformed such that a 0 degree heading, which is incident on the stern in the WAMIT format, is incident on the bow in the Flexcom format.
•The order of translational RAOs is changed from WAMIT format (Surge, Sway, Heave) to Flexcom format (Heave, Surge, Sway).
•The order of rotational RAOs is changed from WAMIT format (Roll, Pitch, Yaw) to Flexcom format (Yaw, Roll, Pitch).
•The units of the rotational RAOs are changed from the WAMIT format of radians per unit length to the Flexcom format of degrees per unit length.
•The reference units of the rotational RAOs (i.e. whether the angle is specified per metre or per foot) may be adjusted if the WAMIT units differ from the Flexcom units. Typically the WAMIT units are ascertained automatically from the external file, but as this is not always possible, you are advised to explicitly state the unit system (along with the file name) in order to avoid any possible ambiguity.
•A positive phase angle in WAMIT format is converted from leading to lagging to conform to Flexcom format.
