A knot and a half seems extreme, but I'm guessing it's your instruments. I
usually pick up less than half a knot in reality, once I have recalibrated
the knotmeter*. *There seems to be a lot of speed trickery going on with
slime and other stuff down below, so throughout the season I keep
recalibrating the knotmeter to reflect reality (as seen by my GPS in slack
water).  Once I have a clean bottom again, I reset the knotmeter to the
base value.
