I consider a knot meter to be a fairly important piece of equipment, and critical if you want to learn to sail better. Why? Because it is the only instrument you have that can instantaneously tell you if your boat is speeding up or slowing down.
Doesn't matter if it is accurate. If you trim the main in a little, how do you know if that helped or hurt? The only way is by looking at the knot meter and seeing if your speed increased or decreased. Again, it doesn't matter if the speed it is reporting is accurate, it only matters that you can see how it changed. Then you will KNOW what your adjustments to sail trim are doing.
Of course, if you don't care to know how changes in sail trim affect your speed through the water, then you don't need a knot meter. As a SAILOR, though, this is something that I consider very important.
