The corresponding Test Parameters screen appears (Figure 5- 16). The data that you see in this screen comes from Navigator’s database, which contains data you’ve saved from various from trips. The parameter definitions are as follows:
Test – Name you choose for this set of test data.
Date – Date of test run.
Quality – Number you assign to represent your perception of the quality of the data collected in this test
(from 1 to 100).
Notes – Your comments about the test data.
HeadSail – Name/code for type of headsail you’re using.
MainSail – Name/code for type of mainsail you’re using.
Awa – Apparent wind angle, in degrees. The angle of wind as measured by your boats instruments. When the boat is stationary, Awa is equal to Twa (True wind angle). When the boat moves, Awa is always less than Twa.
Aws – Apparent wind speed, in knots. The speed of the wind as measured by your boats instruments. When sailing upwind, Aws is always greater than Tws (True wind speed). When sailing downwind, Aws is always less than Tws.
Twa – True wind angle, in degrees. The angle between Twd (True wind direction) and the centerline of the boat.
Tws – True wind speed, in knots. The velocity of the wind relative to the surface of the water.
