In this diagram the right side of the course is shown leading
to the upwind ‘A’ rounding. All competitors in the area are
shown. Each boat is clearly identifiable and the tracker
shows live their speed and direction. One use to Alfred is
seeing what the sailors are choosing to do, for example,
who is tacking too many times while going upwind.
In this example, Arthur is rounding the ‘A’ mark at 2.25
knots while Timothée has lost some speed due to a tack.
Further back, Hanna seems in a good position to round
without tacking while Zoe and Nathan seem to have tacked
too early and will most likely have to tack again to correctly
round the buoy.
Lastly, the full race summary maybe reviewed showing
elapsed times, speeds (max. and min.) and many other
details. In our example below, Jasmine travelled the fastest
with a top speed of 4.03 knots.
All our Dragons tell us they enjoy having these and they are
great for detecting mistakes—as well as successes.
Great thanks to the DFFYS for providing such a wonderful
tool. Of course, should any keelboat sailors like to use
these, please feel free to ask the Sailing Centre.
