The Coastal Messenger could be mistaken for a fish boat to the untrained eye.  

Yet she was designed and built only for missionary work.  Mast is for floodlights and antennas.  

The poles you see on both sides are for paravane stabilizers.  They are in the "up" position in this photo and "down" in the picture below. 

Stabilizers like this are commonly used on west coast fishing vessels.  In the case of the Coastal Messenger, there is no fishing apparatus. Orange buoys lashed at the rail are fenders for tying to other boats or to floats.
