Polars

daknecht,

Q. Where is that data used or displayed?
A. MFD's operating with LightHouse II software are not designed to display polar curves or polar tables. Per section 14.18 Laylines of the LightHouse II Release 17 Operating Instructions, the imported polar table for your vessel is one of the data items which may be used by the MFD to calculate laylines. Should Laylines Type menu list Polars, then polars would have been correctly imported into the MFD. The Laylines Type menu supports calculation of laylines from mirrored TWA, Fixed Angles, or from Polars.
