Small sailing boat compass : Ritchie Sport

[JIM_TERN]

I need a fixed compass for my small 21ft sailing yacht. Not for offshore navigation but enough to see which way I am pointing in poor visibility. Any opinions or experience of the Ritchie brand compass? Looking at their SportXX10 model.

is that model suitable for a yacht or only for a mobo?
