I read somewhere in this forum about mounting a compass so comfort in seating was not hindered. I use a small plotting GPS on my Suncat, but my backup compass is ready. Put two flathead st. stl. screwa in drop board slibe, low on port side. screws protrude about 1/4". Then I filed the 2 mounting holes in the gimbal base to a "keyhole" shape. To mount compass, slip base over the screw heads and pull down. Works really well. I keep compass in a Crown Royal bag for safekeeping. Johnny Walker
