Customer Question
My Raymarine Tridata consistently tracks...
My Raymarine Tridata consistently tracks approximately 2 knots slow. I clean the flywheel every time I go out with no result other than it beginning to count from the moment I leave the mooring. I have accurate information on my chartplotter, but everyone in the cockpit wants to know how fast we're actually going. Is there a correction I can make? Something else, perhaps?

Welcome to Justanswer!

 

You can actually calibrate the Tridata speed settings by performing the steps shown in the Raymarine Users Guide - start at page 28 to access the calibration menu, and follow the steps on page 31 to calibrate speed - since you already have one accurate instrument for speed, you can simply adjust the caibration value unitl you match speed with the chartplotter.
