does your speedo shows correct speed ?
Mine is like this
in 4 kn understates 0.6kn
in 5 kn understates 0.8kn
in 6 kn understates 1kn
in 7 kn understates 1.2kn
I check against GPS
in flat water and drive full circle and get average GPS
speed in circle that should equal speed in water.
It is annoying because of true wind
& true angle. And cant find any instructions for speed calibration.
