You are partly right: The bow wave will have the same speed as the boat.
However, there is a relation between wave speed and wave length. I don't
have the exact formula handy, but a certain wave speed (the speed of the
boat in this case) dictates a certain wave length. If your speed is low, the
wavelength is shorter then your boat, so your boat will be resting on a
couple of short waves, keeping the boat horizontal. When your speed
increases, the wave will become longer, so your boat ends up completely on
the edge of your bow wave. Indeed, you will be paddling UP all the time.
