During the Race

While racing, you are continually trimming the sails and making course
adjustments in order to maximise your speed towards the next mark. It
is important to know whether changes are increasing or decreasing your
performance. The Maxi Display provides Trend and Acceleration
functions to help with this:
The Speed, SOG, VMG-WIND and VMG-WPT pages can be configured
to show Trend or Acceleration indicators: arrows to the right indicate
increasing speed, arrows to the left indicate decreasing speed.
In Acceleration mode, the arrows at the bottom of the display indicate
whether the boat is accelerating or decelerating; they are not shown
when the speed is stable
In Trend mode, the arrows show whether the overall speed trend is
upwards or downwards from a reference speed. By default, the reference
speed is calculated as a rolling average of the actual speed. Pressing
will set the reference speed equal to the current boat speed (or SOG,
VMG as appropriate); the new reference speed will briefly be shown
flashing and may be edited using
return the reference speed to auto calculate mode.
In both modes, the number of arrows displayed indicates the magnitude
of the change; more arrows means a greater acceleration or a faster trend.
The sensitivity of the trend and acceleration indication can be configured
in setup, see page 21.

The Speed page can be configured to show your
acceleration or the speed trend. Use this to assess changes
in sail trim.
To get to the windward mark as quickly as possible it is
necessary to balance pointing angle against boat speed to
maximise the speed directly towards the wind (this speed is
called the Velocity Made Good to Windward).
