More advanced instrument systems make use of additional sensors and techniques to achieve a higher level of accuracy in calculating True Wind.

Movement Correction

Heel and trim angles can be taken into account in the wind angle measurement, along with the heel and pitch of the ship. In this way, we can compensate for the movement induced at the top of the mast when the wind sensor is affected by the movement of the boat.

True Wind Corrections

The True Wind Correction Tables allow you to manually adjust the wind angle according to the deflection effect that the sail plane has on the wind immediately before it hits the boat.

Wind Performance Filter

You can use advanced filtering methods to achieve a True Wind Direction that is more statistically accurate and less susceptible to short-term errors than basic trigonometric calculations.

Polar Tables

Polar tables can be loaded into certain systems to allow an automatic search for the target boat speed and the optimal wind angle and speed based on the current wind angle and speed. This way we can compare the current performance of the boat with its theoretical optimal performance.

Tactical Software

For tactical planning, some software packages such as Deckman from B&G offer the possibility of entering data to calculate future trips: GRIB files of meteorological and current data can be loaded into the software for optimal route calculation. These software packages are connected directly to the instrument system, allowing it to receive updated data from the ship and calculate functions more advanced than those typically available in instrumentation systems.
