The icon for the waves is a circle with a number representing the height of
the waves (shown in units according to measurements preset by the user), see the left
column of Fig. A.1a. It is possible to preset an upper limit for the height of the
waves, and connect this limit to an alarm which will alert and request navigator
action (see the right column in Fig. A.1a).

The weather information received from the C-Forecast server is saved in the
chart plotter's memory. The information can be accessed and used in two ways, by
using the chart plotter in ‘navigation’ mode or in ‘browse’ mode (see Fig. A.1.1).
For every point for which forecast data have been collected, the information
saved to memory contains the data for the subsequent 6 hours from the time of
collection. The area covered by the data in each instants is determined by the maxi-
mum speed of the boat indicated at the time of subscription.
Every point for which weather data have been received, the predictions will
cover the maximum travel distance, if departure happens at the same time as receipt
of the weather data, and the travel speed is at the maximum speed for the full 6 hours.
The significance of this is that there is no need for collecting further information
from the C-Forecast server, until the end of the 6th hour covered by every circle. As
you can see from Fig. A.1b, from the time of collection, the travel time covered is
reduced by an hour until the last hour where you will have to collect a new predic-
tion covering the following 6 hours.
