Maine, I appreciate the need for a proper deviation card in lots of situations, but I also suspect there are many sailors who are almost never in such situations. Day sailors in inland waters who never go out when there's a potential for fog, and carry a GPS... they've (we've) pretty much got it covered.
If I were to plan an extended trip I would certainly calibrate the compass first. I might do it anyway... just for the practice.
