Using Polars to Optimize Your Performance
This section explains how to use Navigator’s Polars plotting
functionality to analyze and fine-tune your boat’s performance.
Intended primarily for the experienced sailor, Polars uses a group
of variables (such as apparent/true/corrected wind angles, boat speed,
heel/pitch, and so forth) to determine what heading you should set
your boat upon to achieve the best possible speed under varying wind
conditions. Analysis results are displayed using several graph plots
and data matrices, which you can modify (edit) to suit your needs.
A typical Polars plot screen is shown in Figure 5-13.
