In my experience with both sailboats and canoes the smaller the bailer the
better it works (I.e. works at lower speeds). Another important factor can
be the placement of the bailer. They work best where the velocity is
greatest. Normally this means at or slightly forward of the longitudinal
center of buoyancy. Keep in mind that they also work best when the speed is
nearly constant. This means that a long slow stroke with considerable speed
differential between maximum and minimum will be less effective than
quicker strokes with a more constant speed. (called a low "Check factor" by
rowers).

There is a bailer that I have not tried sold by Sea Sure (Fig 19-90) that
supposedly works at very low speeds. I hope to try one next year when it is
warmer.
