Hi everyone. My wife and I just purchased a 1992 Beneteau 310 in Toronto & are looking forward to sailing it this summer on Lake Ontario. The boat came with a few things to fix of course: the compass on the binnacle has a broken sun shield which we'd like to fix. I know someone who has a new Ritchie Explorer Surface Mount compass which measures 2 3/4" diameter. The entire unit with case has a diameter of 3 5/8". I don't have the boat accessible right now to measure... does anyone know offhand the size of the standard binnacle compass on a Beneteau 310?
