The
Data readout
panel provides a text summary of the current forecast and some sensor data.
This is shown in Figure 10.
Figure 10: The
Data Readout
panel
The readout information displays the following:
The date and time displayed is the current system time,
not
the time of the current
forecast
Position and heading as computed by the FutureWaves™ Ship Motion Sensor (SMS)
Forecast combined seas and the forecast contributions from wind waves and swell waves
updated approximately every 90 seconds to 2 minutes.
Temperature and wind speed and direction from the FutureWaves™ meteorological
sensor updated every second.
Current ship motion data updated 10x per second.
The ‘Waves’ line describes the Significant Wave Height (SWH). SWH is the “combined seas”
describing the total contributions from both wind generated waves and swell waves. The wind
and swell contributions are combined as follows:
𝑆𝑊𝐻 =
𝑤
+ 𝑠
Where:
w is the wind wave contribution
s is the swell wave contribution
The Significant Wave Height, the period and direction associated with the primary wave
contributor is what is displayed on the Waves line and in the FutureWaves™ banner area.
