As we're planning a significant amount of down wind
sailing soon (Mexico to the South Pacific) and I'm hoping someone can share with me a simple formula or calculator to determine Velocity Made Good. Obviously, sailing deep down wind
is slower than a broad reach but one covers more distance sailing off the rhumb line.
My new Garmin chartplotter
has a Wind Velocity Made Good field but there's no explanation for it. When I'm sailing straight to a waypoint, it shows a negative number, however, when I'm tacking or jibing to a destination
, it shows a positive number.
Perhaps some will say that after sailing for 45 years, I should know the answer to this question and I won't argue. Regardless, I'd appreciate any feedback.
Fair winds and calm seas.
