The bow is no problem as it's usually pointy, but the stern is normally rather round and this could cause you to get a slower speed reading. For example, if you're at 10° AOB the aft-centre of the ship will have already gone past the vertical mark (though you can't see it) by the time the port/stbd aft 'corner' (depending on which side of the ship you are) crosses the vertical mark. It might only add a second or two at worst, but could slightly reduce speed readings.

Hard to explain without a diagram, but hope you see what I mean. Not a big problem but something to consider when stopping the stopwatch in certain circumstances.

I know exactly what you mean and you are correct, but it's never caused me a problem... although, I do tend to take speed measurements when the AOB is in the 45-135 range, which minimizes the error. The main thing I want people to be aware of is that they don't have to be at exactly 90 to get an accurate speed reading... anywhere to the side of the target will be accurate
