  1. After reading some of the recent topics it seems that this Compass 101 info below might be helpful. This is not a comprehensive write up, just a few basic concepts and gotchas that I have learned over time while boating. A compass by itself points to the magnetic North. To get the true North direction, the compass reading must be corrected for two effects. The first is magnetic deviation: the angular difference between magnetic North and the particular compass reading affected by nearby sources of magnetic or electromagnetic interference such as metals and electronics nearby.
  2. I bought a F-50 Ritchie Compass to replace a damaged one in my (new to me) 2005 204SSI. I assumed it was as easy as taking the three screws out... but when attempting today, it hits the window when I lift it out. Am I missing something? Do I really need to take the window out to replace? If so, is that easy to do? Any suggestions would be appreciate. thanks, John PS - LOVE my new boat, so happy to be a Chaparral Owner!!
