Rare earth magnets have a much larger magnetic field than do regular ceramic magnets. If you have a magnet mounted on the foredeck for a reed switch (say, N. pole is UP), you could also epoxy another rare earth magnet in a convenient (and nearby) spot under the deck with the N. pole DOWN), and the magnetic field will largely be contained between the two magnets. Instead of interfering with a compass 12-18" away, you'll have to be half the distance or closer to notice magnetic disturbance in your compass.
