Don,

I have a stack of those magnets for my next boat. With similar concerns, I arranged them on the floor in the proper hatch arrangement. I could not see any deviation, even as close as 12". The lack of influence is due to the polarity in the magnets being vertical while the compass is horizontal. Tipping some of the magnets vertical gave 2 or 3 degrees of deflection (at 12"). I found I had more variation due to where my compass was placed on my concrete floor than due to the magnets.

You CAN influence a compass several feet away with 30 magnets stacked together and held so that the polarity is horizontal. I sense an opportunity for a little fun someday. ;)
