SailGrib WR takes into account all the effects of the current on your boat course:
- drift in current
- change in wind speed and direction
An arrow displays the current strength and direction at each timestep.
The boat icon is rotated according to the Course Through Water the boat has to follow.
The true wind speed and directions (from the grib file) are displayed on the screen.
The Surface Wind Angle is displayed.
You have the choice between 3 sources of current:
- Atlases of currents: for the European coasts. It is by far the easiest to use! SailGrib WR is, as of today, the only app or software to offer such an option for no additional price.
- Grib of currents: they cover the same European coasts for the tidal ones and the entire globe for oceanic ones like the Gulf Stream.
Constant currents: if neither of the former option work and you know that you will sail with a current.
