Measured wind Speed
¼ Note: Only available via the Webserver
Measured Wind Speed is the wind speed measured by the masthead unit, no calibrations
are applied except the factory set off set and Hz/Kt values. Measured Wind is not used whilst
sailing, but is a useful function for checking the operation of the wind instruments before
additional corrections are applied to the data during the calculation of the True Wind and
Apparent Wind.

¼ Note: Only available via the Webserver
Next Leg wind information is a prediction of the conditions of Apparent Wind Angle and
Speed that the yacht will experience after altering course onto the next leg.
This data is calculated from the current True Wind and a bearing that you enter for the next
leg course. From this information the True Wind Angle on the next leg is calculated, then by
using the polar tables the corresponding Boat Speed is given and hence the Apparent Wind
Speed and Angle can be calculated.
Should the leg be upwind or downwind, rather than free, the H5000 calculates the data using
the Target TWA on the favoured tack, this situation is indicated on the display by the position
of a small bar at the top (upwind) or bottom (downwind) of the digits.
The tide calculated by the system can be applied to the calculation if required.
The tide is calculated by the Processor when a position fi xing system is connected.
