4. Figure 6 1 Polars in Deckman are described in a special way at several wind speeds which are adjustable the curve of boat speed versus true wind angle is defined by just five points Although this may be thought to be too few to be accurate the mathematical functions work very well in practice It is important when sailing that the polars can be adjusted quickly and easily and still remain fair with so few points this is 6 1 Chapter 6 Polars certainly the case on Deckman It is better that the curve is close to the real performance rather than extremely precise in places but wildly wrong in others because it is too difficult and slow to adjust or can only be adjusted ashore Moreover performance curves are a bit of a moveable feast and super precision is not possible Deckman does allow you to get your target speeds and angles right because these are two of the points which define the curve Examples of the polars are available on the B amp G website If you select Polars from the icon bar you will be given the choice of navigation polar performance polar or startpolar as discussed in Part 1 Remember that the Navigation polar is used for the calculation of all navigation functions laylines leg calculations and so on and so it is expected that this will be adjusted on a regular basis the Performance polar is used for the calculation of target values so if the helmsman gets used to a particular set of numbers and doesn t wa
