Yes it does.
Once anchored in the Westport (Mass) River the knotmeter was sitting on a steady 5 knots!

I can usually judge my speed fairly closely by observing the bubbles off the stern. This system does not work well when in a current. It is basically opposite. If the bubbles are ripping by I am probably going slower than expected for the RPMs into a strong current. If they are slow moving I am likely moving faster than expected with the current. Does the knot meter give the same “reversed” readings? If anchored in a 2 knot current does the meter read 2 knots? Dan S/V Marian Claire
